BS EN 12600 – Don’t forget about this important regulation!

Glass installation comes with specific building regulations that you must follow for your project’s safety. Neglecting these regulations can lead to unfavorable results. One such overlooked regulation is often BS EN 12600. To ensure a safe installation, it’s crucial to have the correct glass installed for the situation. We’re here to help you understand the basics of these regulations and avoid any mistakes that could compromise your project’s safety.

BS EN 12600 specifies that a pendulum impact testing method should be used for single flat panes of glass used in buildings. The EN 12600 has replaced the British standard BS6206.

 

A weighted pendulum is dropped from 3 heights:

190mm – Class 3 dropped is 190mm, roughly equivalent to a child running into the glass.

450mm – Class 2 is 450mm, roughly equivalent to an adult walking into a glass door.

1200mm – Class 3 is 1200mm, testing for critical applications.

This test is carried out on glass to determine which glass should be used for a specific location. The test also defines the level at which glass will “break safely” (with no large shards). Frameless glass requires extra consideration on installation.

The impact test is carried out using a 45kg weighted soft-bodied bag. It is dropped at different heights to imitate different criteria. It is graded by the height of resistance, the mode of breakage and the height of the breakage.

The glass is then split into categories of how it breaks; this is shown in the table below.

All three classes have a type B breakage which is shown by how the fragments are being held together. This is the typical breakage mode for glazing products such as laminated glass.

This test is carried out on glass to determine which glass type should be used for a specific location.

 

Types of Breakage

Type of breakageExplanationExamples
Mode ANumerous cracks appear forming separate fragments with sharp edges, some of which are largeAnnealed (float) glass, heat-strengthened glass
Mode BNumerous cracks appear, but the fragments hold together and do not separateLaminated glass, wired glass, annealed glass with applied safety film
Mode CDisintegration occurs, leading to many small particles that are relatively harmlessToughened glass (thermally toughened)

The best result is 1B1, which toughened safety glass should always achieve.

When the balustrade is used as edge protection and there is a free path to the glass of 1500mm or more, either Class 1B1 or 1C1 must be achieved whilst using at least 10mm toughened glass.

When the balustrade is used as edge protection and there is a free path to the glass of 1500mm or more, either Class 1B1 or 1C1 must be achieved whilst using at least 10mm toughened glass. This is where a minimum of 21.5mm toughened laminate glass should be used for a frameless glass installation. The 21.5mm toughened laminate uses 2x 10mm toughened glass to reach the EN 12600 and achieves the min. 0.74kN line load required for BS 6180.

Where glass barriers are used for edge protection and the glass is within 800mm of the floor level, the glass must have sufficient strength to provide containment. The glass must prevent people from falling, rolling, sliding, or slipping through the gaps. The barrier must not be designed in a “ladder” style so it cannot be easily climbed, and no gap should be larger than 99mm wide.

Although it can be useful to understand the regulations around glass and balustrades, our team will always double check this with you. Our technical team are here to help advise on what balustrade product and glass you would require for your project. Call us on 01208 261040 or email us at sales@pure-vista.com.

 

Sustainability at Pure Vista

Sustainability at Pure Vista

About our sustainability habits

Pure Vista is based in the beautiful town of Bodmin, in Cornwall. We are particularly aware of environmental issues and how small changes can make us more sustainable. Our office is close to the Bodmin and Wenford railway track and we enjoy listening to the steam train chugging by a few times a day. We are also in the middle of a busy farm, many horses and cows reside here as well as chickens, cats and dogs. Cornwall is famous for its outstanding natural beauty and good sustainability track record. In 2021 the G7 summit was held just down the road from us, where the world leaders gathered to discuss and plan global sustainability issues. This had a major impact on the tourism market and Cornwall is now in full tourist mode.

In the Pure Vista office, we are easily able to recycle everyday items, similar to any household, such as milk bottles, plastics, paper, cardboard, magazines etc. This gets collected up by the local recycling team every other week along with the recycling from the farm residents and holiday cottages.

The small things make a big difference. In the office we use a waste paper basket and open the windows instead of turning on the air conditioning. We also use plastic-free tea bags, because trust me…we go through a lot of tea bags! Our office is relatively small, but we have a selection of real plants. They help keep our air clean and increase productivity, and we know that plants make us happy!

We are as paperless as we can be, making the most of emails to send invoices and order confirmations to our customers. Being paperless has become the norm for many businesses and we have no problem continuing this. Limiting our printing use to stickers and packing notes for our warehouse team.

The Covid-19 pandemic did throw a massive spanner in the works for us (along with everybody else!). Keeping windows and doors open became a safety requirement to keep the air fresh for office employees and visitors. Many of our people ended up working from home where necessary, massively reducing travel times. One member of staff has now committed herself to walking into work each day, no matter the weather! A courageous promise in our Cornish climate. Others are able to car share, again reducing car usage. The pandemic also delayed and eventually stopped plans for new products and packaging designs, these are slowly ramping up again as businesses open and catch up with 18 months of setbacks. There has been huge growth in the domestic market for balustrade as people have the time and resources to create new gardens and take on more projects at home. We pride ourselves as being the best stockist of balustrade in the UK but even we have been tested while keeping up with demand these last few months.

Aluminium

Our products are made from Aluminium which is an infinitely recyclable metal. This means it can be used and recycled over and over again as many times as required. Aluminium is currently used in products such as drinks cans, food tins and the Pure Vista balustrade systems. The balustrade we manufacture is almost certainly made from recycled products. We are also able to recycle our off-cuts. These are created when we have to cut a balustrade to a certain size, leaving us with a small length of unusable balustrade. This can be collected and recycled back into something new for example, it could end up as a cola can or in a smart phone but it could also end up in a plane or a rocket!

What’s next?

We are working on ideas to make our packaging more environmentally friendly and recyclable. At the moment our packaging includes plastic and cardboard. In the past we tried only cardboard, which was recyclable, but was unsuitable for the job it needed to do, resulting in damaged products and packaging. But, we’ll keep trying!

The next stage for us, is to implement and use plastics which can be recycled. However, we are worried that when our package arrives on a bustling building site, the waste is disposed of without a consideration of recycling. To reduce this and encourage recycling, we are planning to add “recycle me” labels to our recyclable packaging.

Working on being more paperless, creating our emissions by changing our travel habits and continuing to work with an infinitely recycled product is helping us on the way to becoming more sustainable.

We are working on becoming a more sustainable organisation, our small changes are just the beginning. We are not perfect but we do hope to be able to make significant changes throughout our supply chain to encourage more sustainability in the future throughout our organisation and the glass industry.

Preparing for Martyn’s Law with Pure Vista

Anti-terror Glass Balustrade

For further information on our anti-terror frameless glass balustrade please contact our technical team who will be able to assist you.

BLASTguard and BULLETguard are Pure Vista’s anti-terror frameless glass balustrades. One is able to withstand a blast and the other stops a bullet. The use of these frameless balustrades in a building can reduce damage and save lives. The fully patented design is easy to install. BLASTguard has a 3.00kN loading to BSI Standards and BULLETguard has 1.50kN loading. Used in stadiums, offices, airports and train stations globally, this channel is rapidly growing in popularity.

Protect Duty has definitely increased the interest and sales of this product. Organisations and architects have become more aware of their increased responsibility to provide safe environments. Glass balustrade is a solution that protects while blending into the building design. Glass seamlessly blends into the background or it can be highlighted as a feature, whichever is chosen, the positioning is important.

If you’re considering using a frameless glass balustrade for safety aspects, you should take time to deliberate about areas that people will gather and how they can be shielded. Using glass is a clever way to increase anti-terror protection without giving the impression an area is a potential threat. This fortified balustrade is currently being installed on the HS2 project. It is used throughout the main stations and airports to add safety barriers and anti-terror protection.

Martyn’s Law (Protect Duty) is a pledge by the government to improve safety and security at public venues and places. It appears that all Publicly Accessible Locations (PALs) that have a capacity of more than 100 people will be required to implement some change. The requirements range from staff training to implementing suitable mitigation measures to PALs. The GOV website includes details of public consultations. The results show that the government would need to support, through funding and resources, any organisations that would be required to make any changes. It’s expected that by early 2024 this will become legislation.

BLASTguard was the first completely frameless, bomb-resistant glass balustrade on the anti-terror market place. Where a bomb blast is a perceived threat, 3kN glass balustrade can be used. Using screw-clamp technology, the glass can be aligned for a perfect finish. The fortified MEGAgrip is ideal for public locations where crowding is likely. Currently installed as a safety barrier in stadiums, London train stations, underground stations, airports, hospitals and large music venues around the world.

BULLETguard is typically installed in public areas, as a protective screen to ensure the safety of a particular delegate, speaker, politician or celebrity who may be at risk. Another fortified variation of the MEGAgrip channel, this variation wields a different result, safety from bullets instead of a blast.

Pure Vista supply organisations globally with quick delivery and unparalleled technical support.  Aiding on infrastructure design, the positioning of a balustrade can be the answer to containing a blast. The team at the Pure Vista offices in Cornwall, can provide expert technical advice to aid in the planning and design process.

5 reasons we love Juliet balconies

The Juliet Balcony, made popular by the famous balcony scene in Romeo and Juliet, is a unique addition to any home. It is typically installed in front of a window or first-floor door, allowing the window to open fully and transform into a balcony. You may have heard them referred to as French Balconies or Faux Balconies, and at Pure Vista, we call our system ARIA. This style of balcony, widely used throughout France and Italy, is growing in popularity in the UK. The ARIA system from Pure Vista is a sleek and modern take on the traditional Juliet Balcony. With this system, you can enjoy the fresh air and outdoor views while standing inside your home as if on a balcony. The ARIA system is easy to install and is made from high-quality materials, ensuring durability and longevity. Whether you live in a city apartment or a countryside cottage, the Juliet Balcony can add a touch of elegance to your home. Contact us today to learn more about the ARIA system from Pure Vista and how it can transform your living space.


1. Increased Light

Looking to increase the amount of natural light in your room? The Juliet Balcony is the perfect solution! By using a full-length glass door, this balcony system maximizes the amount of sunlight that enters your space without obstructing the view.

2. Safety

Our top priority is safety. That’s why the solid glass panel is installed close to the wall, reducing the chance of small items falling through gaps. Not only that, but the system is also strong and secure, tested to 0.74kNloading, making it suitable for domestic installation.

5 Reasons to Install Privacy Glass

Privacy screens are a practical solution for homeowners who value their privacy. Comprising a type of glass balustrade that is usually taller and not transparent. Privacy glass balustrade is becoming very popular for balconies. The taller screens also help add extra protection from the weather, a bonus here in the UK!

Used on one side or all sides, this method can greatly improve your privacy and create a secluded balcony area.

1. increase your privacy

Installing a privacy glass screen on your balcony, patio, or garden can significantly enhance your privacy. You can choose from a variety of design options, including tall screens, half clear and half sandblasted screens, or screens with patterns on them. The type of screen you choose will depend on where you plan to install it. With a glass screen, you can create a stylish and practical partition that will protect you from prying eyes and wind. It’s a great way to enjoy some privacy while still enjoying the outdoors. So, if you’re looking for a simple and effective way to enhance your outdoor living space, consider installing a glass screen today.

2. increase your neighbours privacy

The privacy you’ve added to your property will not only benefit you, but it will also be appreciated by your neighbours. With the addition of privacy features, you will no longer be able to see into their property, and they will no longer be able to see into yours. This increased privacy can create a more comfortable and secure environment for everyone. Your neighbours may feel more at ease knowing that their activities are not being observed, and you can enjoy your own home without feeling like you are being watched. Enhancing privacy is a great way to create a sense of separation and seclusion, which can lead to a more peaceful and enjoyable living experience for all.

privacy glass on balcony3. acts as a windbreak

When considering a privacy screen, going for a taller option can provide multiple benefits beyond just privacy. One such benefit is added wind protection. A tall glass screen, for instance, can effectively block wind and create a more comfortable outdoor space. This can allow you to enjoy your outdoor area more frequently and in more varied weather conditions. So, if you’re looking to make the most out of your outdoor space and create a more comfortable environment, opting for a tall privacy screen may be the way to go.

 

4. it’s a legal requirement

Depending on the location, your local council planning team may specify that you have a privacy screen when you install a balcony with a glass balustrade. This is typically due to the balcony’s height and proximity to neighbouring properties. You can obtain further information on this requirement by visiting your local council’s website.

5. safety barrier

When it comes to balconies and any areas with a drop, safety should always be a top priority. Installing a barrier is essential to prevent falls and accidents. Glass balustrades are an excellent option for this purpose. This type of railing is popular because it provides a strong, sleek and modern look, while also allowing you to enjoy the view or add privacy. Glass balustrades come in different designs and styles, so you can choose the one that best suits your needs and preferences. Additionally, they are easy to clean and maintain, making them a practical choice for any property. With a glass balustrade, you can enhance the safety and aesthetic appeal of your space.

By using a privacy screen, you can keep your property safe from curious onlookers while still enjoying the benefits of an open space. These glass screens are ideal for outdoor areas that are overlooked by neighbouring properties, or for balconies and decks that face onto public areas. They are also great for creating a sense of seclusion and intimacy within your property.

With a range of designs and styles available, there is a privacy screen to suit every taste and budget.

Fire ratings for glass balustrade explained

Glass Balustrade is on the (high) rise!

A2, S1, D0 EN 13501-1
Fire rated glass balustrade

Fire rating for glass balustrade can seem difficult to understand.

We have written this to help you understand fire-rating codes and the achievements of our products.

Our fire-rating test reports and rating are available here.

Pure Vista’s rating for POSIglaze and POSIone is A2, S1, D0 rating which means that means POSIglaze and POSIone will not be any contribution for spreading fire.

Why have we had our products fire rated?

fire rated glass balustrade

Why have we had our products fire rated?

In 2018 the regulations have changed to increase the requirements from products that will be used at 11m and higher. As a response the tragic Grenfell Tower fire, these regulations are mandatory to increase the safety of buildings and reduce the spread of fire.

For any project that involves residential living space above 11 meters high (or over the 3rd story), be aware that to comply with fire safety regulations, a fire-rated balustrade will need to be used throughout the entire project, not just above the 11-meter mark.

To be installed our products must now meet EN13501-1 as standard and have fire rating for installation over 11m high.

Achieving the A2, S1, D0 EN13501-1, POSIone and POSIglaze can be installed at 11+ high. We have tested each induvial component, not only the channel as a whole system, ensuring it’s the safest we could provide.

You can read more about that here (fire testing blog)

The national classifications do not automatically equate with the transposed classifications in the ‘BS EN 13501-1 Classification column, therefore products cannot typically assume a European class unless they have been tested accordingly.

— Fire Safety Approved Document B, P191.

What is the Euroclass system?

fire rated glass balustrade

The European classification standard EN 13501-1:2018 ranks construction materials in seven classes with regards to their fire behaviour: A1, A2, B, C, D, E and F. The same document also gives a classification of these materials with regards to smoke development (s1, s2 and s3) and the formation of flaming droplets/particles (d0, d1 and d2).

  1. Fire Behavior

A1 = non-combustible material

A2 = non-combustible (Scotland) and limited combustibility (England and Wales)

B, C, D = ranges from very limited to medium contribution to fire

E, F = high contribution to fire

  1. Smoke Development

S1 = little to no smoke

S2 = quite a lot of smoke

S3 = substantial/heavy smoke

  1. Formation of Flaming Droplets/Particles

D0 = no droplets

D1 = some droplets

D2 = quite a lot

Pure Vista’s rating for POSIglaze and POSIone is A2, S1, D0 rating which means our product is classed as non-combustible with little to no smoke and no droplets within the first 10 minutes of fire exposure.

That means POSIglaze and POSIone will not be any contribution for spreading fire.

The safety of Annealed glass

Is Annealed Glass safe for Balustrades?

Broken Annealed glass in a testing facility

Is annealed glass safe for balustrade?

At Pure Vista, we continue to strive for the highest level of safety from our products. All our products undergo strict in-house testing to ensure all products reach a safety level we are satisfied with. This is how we have become one of the most trusted glass balustrade names in the industry.

A couple of years ago we were approached with a new glass product which offered lots of benefits; it’s clearer, quicker to supply, strong when broken and most appealing, the cost savings for customers. One thing which was glossed over, the glass was Annealed.

The biggest disadvantages to annealed glass is that it is easy to break and when it breaks into large shards. The large shards are more dangerous than tiny pieces shattered glass.

Annealed glass will break with relatively low impact. For example, a door swinging into the glass, or an accidental kick could result in the glass breaking. Glass which breaks easily is also costly to repair time and time again!

In 2021 we began exploring if and how we could use annealed glass with our balustrade products. We saw the benefits and how this would be better for our customers. Is it too good to be true?!

We began by trying Annealed glass with our POSIglaze channel. POSIglaze is our most used and trusted product, we know it works excellently with toughened and laminated glass.

Initial in-house line load testing went well, but the glass still didn’t meet building regulations for this purpose (frameless glass balustrade). To pass and meet the regulations, we would have to carry out multiple product tests. At the time, only toughened and laminate glass types are covered by the British Building Standards for our intended use.

The next stage in our research uses a third party to perform certifiable tests. We know that Annealed glass is easy to break, so we were surprised when it passed the line loading tests.

The second test of the day was impact testing. Starting with a low height and low joule, the glass passed. However, as the test progressed the glass showed weakness and shattered. Once the glass has broken, no further testing is carried out.

Annealed glass is not suitable for frameless glass balustrade.

The images show the glass after the test which broke the glass. You can clearly see the points that were held by our balustrade channel clamps, 4 along the bottom length of the glass. The glass broke into 2 pieces when it was moved out of the channel and into a safe area. You can see this in the pictures; the glass has completely broken with large spider web pattern.

It got us thinking, if this could happen in a safe testing zone, we could only imagine the risk this poses on construction sites, homes, and public spaces.

Our products are compatible with a range of glass types and thicknesses, read about glass types here.

We will never suggest that Annealed glass is used for frameless glass balustrade because it failed the testing. We have other glass options which are readily available and surpass the regulations.

Types of Glass

Choosing Glass

There are several options when choosing glass.

Different types of laminated glass are available where the interlayer changes for example but there is also several optional extras which customers can choose from. Naturally these have pros and cons which need to be considered.

Why toughened glass?

Toughened glass (fully tempered) is far stronger than annealed glass. It is heated up and cooled to harden it. It is not only stronger but when it breaks it goes into very small fragments. These are safer than larger shards of glass.

Toughened glass requires a handrail, this significantly reduces the risk of breakage. However, should a toughened glass panel break, it’s not unheard of for glass fragments to travel over 100m from its original position. Handrail will also reduce the risk of falls should the panel break, by acting as a second barrier.

It should be noted that although a handrail is a second barrier in this occurrence there will still be a big hole between the floor and handrail. This is a safety concern, especially for small children that may not see the handrail or the missing glass panel.

In both instances, should a breakage occur, the area needs to be immediately cordoned off whilst a replacement is sourced.

Heat strengthened glass

This glass goes through a similar process to toughened glass but using lower temperatures. This means the glass is stronger than annealed, however it will break into large chunks. Typically, suppliers will only want to work with toughened glass because of the increased safety.

What is heat soaking?

Glass can have an impurity in it called a nickel sulphide crystal. These cannot be seen by the naked eye. The build ups of nickel sulphide expand in heat at a quicker rate than the rest of the glass and this can lead to spontaneous breakage.

During heat soaking glass panels are placed into a bath and heated up. That means the impurity and breakage are found in the factory, rather than in situ. Reducing mess, and expense for the customer on site.

The disadvantage of heat soaking is that the toughened glass now breaks in larger chunks. This isn’t a problem with laminated glass but with standard toughened it is more dangerous overhead. We always advise laminated glass is used in overhead installations to avoid injuries.

Low Iron

When you look at glass panels side-on you will notice a strong green tinge, this is the iron element. This also affects the clarity of the glass panel, especially with the thicker glass types which are needed in balustrade.

You can request low iron glass, giving you a noticeably clearer glass. From side on this will now look more blue than green. As expected, there are additional costs for this. For increased clarity, you should use an extra strong interlayer.

Why laminate glass?

Building regulations dictate that for a frameless glass installation, toughened laminate glass must be used. This is because when one panel breaks it remains attached to the other. No exploding! The glass would shatter is a spider web fashion and will remain in place until removed.

Should a breakage occur, the area needs to be immediately cordoned off whilst a replacement is sourced.

Different Types of Laminates:

PVB (Poly Vinyl Butyral) 

PVB is the most popular choice for laminate glass in the UK. Made up from a flexible layer of plastic between two sheets of glass. Sandwiched together and placed into an autoclave to bond the glass panels together.

The interlayer is a highly flexible sheet. So, if both glass panels broke the glass would fold over onto the floor. Should one leaf of glass break, over time, the weight would possibly break the second panel.

This is the cheapest option for toughened laminated glass.

PVB is the worst performer for water resistance and can delaminate when water is sat on the interlayer for long periods of time. We advise you to put drainage holes in the base channel to clear standing water and prevent laminate breakdown over time.

ES PVB (Extra Strong/Stiff PVB. DG41 Brand).

These are designed to cross the bridge between PVB and SentryGlas. They are stronger, clearer and more water resistant than standard PVB.

Unfortunately, the cost of this is so close to SentryGlas. It’s often more beneficial for the customer to pay the higher price and gain the far superior performance of the SentryGlas.

EVA (Etyleen Vinyl Acetate) 

Several years ago, EVA was the most common form of laminated glass, and it’s now making a comeback. Like PVB and SG laminates, the interlayer is a flexible sheet. It creates a strong bond between the glass panels. This increases the water resistance on decreases chances of de-lamination. However, this glass is more costly than PVB. Another disadvantage for EVA is that it’s not as strong under force loading, the interlayer can also become discoloured when exposed to UV for long periods of time.

Ionoplast (Most common SentryGlas Brand)

The interlayer used in Ionoplast is a rigid sheet placed between the glass panels. It has a very high tear resistance, making this the strongest type of laminate glass. Even if both sheets of glass broke, they would remain standing and able to withstand force for some time.

SentryGlas has good protection against moisture absorption, delamination will only occur after many years in situ. It also has a strong resistance to UV damage and is not likely to discolour.

The major benefit to SentryGlas is its clarity: providing the clearest interlayer. Combined with a low-iron glass, it’s nearly invisible!

Fire Rated Frameless Glass Balustrades

Balustrades safe to use 11m and higher according to BS EN13501

We are proud to announce that both our POSIglaze and POSIone have successfully passed the fire testing required for installations on projects over 11-metre-high according to BS EN13501 building regulation. After a great week of product testing in Frankfurt, we are able to confidently say that these Pure Vista balustrade channels are fire rated to A2, S1, D0, EN 13501-1 and have reached the line load of 0.74kN. 

Pure Vista Ltd is the only balustrade manufacturer who has fire tested their full systems. Giving assurance the system is going to be safe. The photos below show the system being tested at an accredited laboratory. Report available on request.

POSIone FR is able to use 1300mm high glass panels and achieve the 0.74kN line load.

How is our testing different to competitors?

Pure Vista partnered with Pyroguard to test both the glass and balustrade in conjunction. Ensuring that the system as a whole surpasses the strict requirements laid out by the UK government. Meaning we tested the channel alongside all the internal components and glass for a complete system test. It was important for us to be able to provide the safest fire-rated system available.

Other systems are solely looking at glass performance.

We also considered how we can keep this product as affordable as possible without needing to compromise on safety. We looked at the glass being used. The 19mm glass variant only just passed the line loading it was too close for comfort when considering difference between real-world and test conditions. We also decided that the 25mm would be too expensive for the majority of budgets. Therefore, the 23mm gave us a great balance of strength with cost effectiveness and more importantly, safety on both elements of line loading and fire safety.

   

What makes glass balustrade fire rated?

To meet the specified regulation both the glass used, and the balustrade channel must pass the fire testing. Traditional laminate glass has interlayers that are combustible, a different type of glass must be used. Pyroguard have developed a type of laminate glass which can pass the testing and is the safest option to use. This is the glass we will be recommending with our balustrade for projects which must meet this standard.
These 3 images show the testing process on POSIglaze base-fix balustrade. Before, during and after the test.






As you can see from these images, the channel, handrail, and glass frame has held the glass securely throughout a blaze. Even though the glass has broken from the intense heat/cooling, it has not exploded but remained contained. The channel has held strong and only shows signs of burning.

Both POSIglaze and POSIone have now passed testing to achieve the fire rating of A2, S1, D0, EN 13501-1 with line loading of 0.74kN.

Glass Balustrade for high rise buildings

POSIone is installed and adjusted on the safe side of the glass meaning any replacements can be easily carried out. Enabling a safer installation on projects with glass balustrade, including over 11 metres high. The newest product to join the world-renowned Pure Vista range of frameless glass balustrades can be used at this height due to the testing it has successfully passed.

Our testing has gone above and beyond the necessary requirements to improve the safety for homeowners. Our priority is to make the best product for our customers, even if that means higher investment in research, development, and testing.

In the end – you get the very best we can provide!

Privacy Glass Balustrades


How can I increase privacy on my balcony?

Privacy glass balustrade is becoming popular for balconies. Use of frosted glass to shield the balcony from view of neighbours and passers-by. A privacy screen should be opaque glass or screening to obstruct the line of sight.

Used on one side or all sides, this method can greatly improve your privacy.

In the gallery below you can see multiple examples of how privacy glass has been installed on the side of the balcony. Another great way is having 3/4 privacy glass so you don’t lose your view from on the balcony, but people can’t see up at you from on the street.

The taller screens also help add extra protection from the weather, a bonus here in the UK!

Privacy glass is really easy to maintain with a balustrade. Warm soapy water once in a while, helps keep the grime off the Aluminium balustrade and you can use normal glass cleaner for the glass screens.

How tall can Privacy glass be?

Most domestic installations will be able to install either POSIone, POSIglaze or the SPIG-LITEadvanced system from us. The height of the drop regulates how high your glass must be as well as the glass thickness.

For domestic frameless balustrade:

MEGAgrip Max glass height: 2000mm

POSIglaze Max glass height: 1500mm

POSIone max glass height: 1200mm

SPIG-LITEadvanced max glass height: 1200mm

If you decide to use glass stiffeners and railings, the max glass height increases.

Please check your project against your local building regulations to ensure the safest product for your project.


Where to use privacy glass screen

There are loads of places where a privacy screen will be a great addition.

Balcony & Juliet balconies, hot tubs, mezzanine layer, stairs, garden walkways, windy patios or bin stores.

Advantages of Juliet Balcony

Find out why we love Juliet Balconies and about our ARIA Juliet system


ARIA Juliet balcony
Fascia Fixed ARIA Balcony

WHAT IS a Juliet Balcony?

Named after the famous scene from Romeo and Juliet, the Juliet Balcony is placed in-front of a window or first floor door. Allowing the window to open fully and transform into a balcony. You might have heard them called French Balconies or Faux Balcony. At Pure Vista, our system is called ARIA.

You can stand inside your home as if on a balcony, letting the fresh air in. Widely used throughout France and Italy, this style of balcony is increasing in popularity here in the UK.

Using two sides of channel which fix onto the wall around the window and a solid glass panel held between them.

Due to easy and quick installation, you can have a Juliet balcony complete within a very short amount of time.

Why we love Juliet Balconies

1. Light

Juliet Balconies are a perfect way to increase light in your room. The use of a full length glass door massively increases the sunlight pouring into the room, the glass balcony will not obstruct this.

2. Safety

The solid glass panel is installed close to the wall of the house. This significantly reduces the chance of small items falling through a gap. The system is also strong and secure, tested to 0.74kN loading making it suitable for domestic installation.

3. Increased Ventilation

With a Juliet Balcony installed, you are more likely to have the door open more often. The flow of fresh air into your home will work wonders!

4. Subtle in appearance

The channel profiles used for a Juliet balcony are thin in comparison to traditional glass balustrade. They will not be seen from inside the room and are subtle enough to suit any property from the outside. They are available in a range of colours, raw Aluminium can even be powder coated to match any colour. At Pure Vista, the ARIA is supplied in Silver Brushed as standard, but is also available in Black and Anthracite Grey will be available soon.

5. Cost

In comparison to traditional balconies, the Juliet Style is much more cost-effective. Supplied in one compact box and delivered to you, this balcony system is popular for it’s simple storage. You will have a balcony without an extension. In most cases, you will not need planning permission for a Juliet Balcony, but please check with your local authority before work begins.

Mark, Pure Vista Director said “We were constantly having to help installers or architects get around the issue of having a balustrade installed on to a timber framed building. We ourselves had to come up with some interesting get arounds or simply having a total redesign. This plate opens up having balustrade fitted to timber which installers can walk away happily knowing it will be secure. The timber plate can be incorporated with our BalconySeal® system to provide a waterproof installation”.

Compatible with POSIglaze base fix this new addition will allow frameless installations onto timber safely. Adam, one of Pure Vista’s Directors said “We are excited to the launch the Timber Fixing Plate, The Timber Fixing Plate is our innovative new secure method of installing balustrade channel to timber. The plate is engineered to spread the load and minimise the risk of splitting or crushing the timber, while also preventing the fixing from pulling out under extreme loads”.

Pure Vista Product Development


Product Development at Pure Vista

Learn how we move from the initial idea to the finished product

You’re joining us at an exciting time, we are in the part-way through developing some new products! This month I’ll take you through the product development process here at Pure Vista and hopefully give you an insight into how we get things done.  Our process is much like everyone else’s in all other industries. We start with an idea, then move into design before production and finally the selling of the final item.

1. The Initial Idea

At Pure Vista we generally get our ideas from speaking to customer’s finding their needs or frustrations on site.

We receive a wide range of enquiries and have access to many building projects allowing us to see new emerging building design concepts and what the customer will be requiring. The team are always listening to what installers and customers are talking about, suggesting and requiring.

Our aim is, and always has been, to have the most user-friendly systems on the market. These come from the simplest smart ideas using strong high-quality materials but always keeping the installer in mind.


People working together at a laptop

2. Design, Concepts & testing

Now the cogs start turning for Mark and Adam as they start to bounce ideas off each other; make sketches, get louder, demand tea and biscuits and do clever things. When an agreement is made and any obvious design flaws have been fixed, the transition to CAD begins using special computer software. This irons out any weak points, adds strength to profiles where stress levels are too high and visibly seeing a 3D model helps to mold the final design.

At Pure Vista we have our own 3D printer to create first samples of products quickly, this allows us to try installation methods. Making sure the installation will run simply and smoothly in the real world is a big part of our product development.

Now everything is set, a small batch is produced from the Aluminium extrusion plant and other suppliers. In-House testing is carried out which involves the usual testing for building regulations and then the more extreme ‘what if it this happened’ testing. We can then move on to official testing which we carry out at a 3rd party laboratory.

The tests required can change depending on what the product will be used for. For example, our BLASTguard and BULLETguard have undergone extensive testing using explosions and bullets, however these tests are not necessary for a product like the SPIG-LITEadvanced which cannot be used as a blast resistant barrier.



3. Production

This is the easy part; our products are manufactured! A few select installers are shown the products and their workings which gives us an insight on how products will be received. It helps us understand their thinking and how we should approach writing the installation instructions.  Once they have been made and the products have passed our quality assurance assessments, we can happily begin to promote and sell the new product. Instruction manuals and product brochures will be created and ready by the time the product is ready for sale. Our warehouses will fill up and be ready for product launch.


4. Selling

Now everything is in place we can hit the GO button. Components have been produced to the highest standards and they are now ready to be used. Our marketing team will let you know that we have something new to try, product samples will be sent and the new product is available in the shop! We’ll wait for installation images to come back and we can use these for further promotion of the product and of the installers.

5. Little extras

We now also offer customer fabrication on some of our channels, this allows the channel to be made to perfectly fit a build without the need for cutting on site (More info here).

For the right project our channels can be powder coated to any color, allowing some wacky and fun building designs.

I also love to see our products in situ, contractors and installers send in some lovely images of finished projects and stunning houses. Not all are suitable to share on social media but it’s interesting to see where our products are. Remember to keep tagging us in your photos, glass staircases, balconies, Juliet balcony, glass railings and handrails. We love to see them all!

So, there you have it, you now know how our products are developed!

If you need help or advise on a project please do contact us, our friendly team are ready to help answer technical Q’s, look at drawings and help you make the right product decisions based on building regulations.

We also have lots of technical guidance on our website, including PDF drawings, installation guides and testing data.

As you might well already know, our online shop is quick and easy to use and it’s open 24/7 so please make the most of it! You will still benefit from quick delivery times and have access to our tech team if you need us.

January 2022


Plans for 2022
January newsletter

Well, here we go again! What does 2022 have in store for Pure Vista?

Let’s start at the beginning, January. We are back and operating from a well-deserved Christmas holiday. It’s all hands-on deck for the next busy season as development sites re-open and work resumes.

In the first quarter of the year we are hoping to release new products and extra adaptations of our current range. We have been listening to you and what you want to see and what problems arise during installation. We look forward to bringing these to market making installation life simpler. Adam will be frequently visiting the test site, preparing products and ensuring that they are suitable for use and that they do what we want them to do. Testing not only provides trustworthy results, it also gives us the opportunity to see how our products react under different pressures and installation styles; such as on steel or concrete. For those who are interested, we’ll be doing a detailed blog on product development this year too. That will focus on a new POSIglaze one-side-fit channel.


There is a huge theme running through the coming year and that is counter-terror. Martyn’s Law (protect duty) will be discussed in parliament in first half of the year. Introducing more safety measures on public spaces that may have a terror threat. These will range from extra staff training to inserting physical safety precautions, including blast and bullet resistant balustrades. Our BLASTguard and BULLETguard balustrades will feature in magazines, blogs and articles throughout the year as this is a sought-after product with the potential new legislation. Look out for us in anti-terror business magazine and the RIBA catalogue. We are also working with a local designer to create some realistic artwork renders that will show how our products can be used in domestic installations and the public safety domain. With the knowledge that Protect Duty will be discussed soon, we are expecting increased use of our BLASTguard and BULLETguard.

Team development

We are expanding our team again this year! A new business development manager will be joining the team soon and Adrian will be visiting you up and down the country showing you the new products. After the successful hire of a new warehouse assistant, we are able to get orders packed and shipped quicker than ever, thanks to the great team work from Diane, Zen, Lee and Darroyl. Ruth, the Marketing Manager continues to cover all bases from website administration, social media, article writing and everything in between as she heads into another busy year. Directors, Mark and Adam are excited to be launching the new products and happy to continue to support our customers with excellent technical support. Viv our office manager, who you all know and love, is looking forward to chatting to our regulars and developing new relationships with new ones.

Projects

Pure Vista have been fortunate enough to get specified on a range of large projects throughout the UK that will begin work on site this year. We have been working closely with designers and engineers of HS2 and other rail stations undergoing redevelopment where they are planning the use of our MEGAgrip/BLASTguard balustrade systems. Hundreds of domestic installations have already been planned and supplied by our worldwide customer base of installers.

We’ll be heading off to the FITshow22 in Birmingham, UK in May and planning to exhibit at GlassTec in Germany this September. Come over and say hello and we’ll be happy to show you our products.

As always, if you have installed any Pure Vista products we’d love to see pictures and share your work with our audience and new customers. Small or large projects, we love to share images on our social media channels and we also send people images from installers so they can see how Pure Vista products can be used for some inspiration!

We are lucky to be working in beautiful Cornwall and we are thankful for our loyal and new customers. The continued service from customers worldwide is astonishing and we work hard to provide the best quality product and top-notch customer service.

Let’s see what exciting things the new year brings…. Here we go!

A message from the Pure Vista Directors Mark and Adam.

The year 2021 has been an exceptional year for Pure Vista for product sales despite the challenges of the pandemic and supply chain issues throughout the year. We wish to thank our customers and staff for their patience during these difficulties, the staff have been committed to providing the best service possible to our customers and have gone above and beyond to do so.

Pure Vista going into 2022 hope to have new and exciting products being launched and we are really looking forward to this year and its prospects.

Avoiding Glass Delamination and its Associated Problems


VISTApedia logo 03

AVOIDING GLASS DELAMINATION

AND ITS ASSOCIATED PROBLEMS


what-is-laminated-glass

WHAT IS LAMINATED GLASS?

Glass that is being installed into a building has very specific safety standards to adhere to, particularly with respect to glass type, requirements of which vary widely according to the location and purpose of the glass. Windows for example, typically require the use of annealed glass (sometimes called float or sheet glass) but this wouldn’t be appropriate for structural glazing such as balustrade, because annealed glass doesn’t meet the line load requirements for use as a safety barrier. Heat strengthened glass is a fortified version of annealed glass, produced by heating and slowly cooling it – this extra fortification can enable the glass to be used for structural installations, again depending on the line load requirement for the specific purpose. Toughened glass is another fortified version of annealed glass, where increased strength is achieved by heating the glass to an even higher temperature before cooling it rapidly. Toughened glass is typically used for glass door panels and low-level windows as well as some structural glass installations such as balustrade.

Any of these glass types can be sandwiched together to create laminated glass and in respect of balustrade, it is normal practice to bond two panes of toughened glass. The glass is bonded using an interlayer, typically plastic or glue, although there are many main types of interlayer each with its own characteristics. The most common interlayers include PVB (Poly Vinyl Butyral), EVA (Ethyl Vinyl Acetate), SGP (Sentry Glass) and CIP (Cast in Place).

While laminating two sheets of glass together doesn’t necessarily amount to a higher force loading capability (due to movement of the two individual panes of glass under pressure), it is a much safer material to use for balustrade. With laminated glass, in the unlikely event that one pane of glass breaks, the glass shards will largely remain stuck to the interlayer avoiding further damage and potential injury resulting from displaced broken glass. Additionally, in the event of a breakage involving one layer of the laminated glass, there is still a second layer that can serve as a temporary barrier until the pane can be completely replaced.


how-can-glass-delaminate

WHY DOES GLASS DELAMINATE?

Water immersion is the primary cause of glass delamination, so when using laminated glass in an external installation it is important to consider a water drainage solution for the channel. If water is allowed to collect inside the channel, it can begin to seep in between the interlayer and the two glass panels and over time the seepage will grow, causing the layers to separate.

A secondary, but less likely, cause of delamination is the collection of rainwater in the tiny groove at the top of the laminated glass, between the two glass panels and above the interlayer. This only happens if the interlayer doesn’t finish flush with the top of the glass and in a particularly wet environment when the water caught in the groove doesn’t get a change to evaporate naturally.


effects-of-glass-delamination

WHAT ARE THE KNOCK-ON EFFECTS?

Glass delamination usually takes place from the bottom up, since the area affected by water immersion tends to be at the bottom of the glass, inside the channel. The first visible signs of glass delamination is a cloudy opaque quality to the glass, working its way up from the bottom. Opaque glass of course, defeats the purpose of using glass as a material in the first place and the discolouration can look unattractive.

Once the delamination process has started, it escalates rapidly and the glass will need to be replaced, even if the cause of the delamination is addressed. When wind hits laminated glass, it causes the individual panes to vibrate which the interlayer allows for, except when it is perished which can result in the glass panes vibrating against each other causing breakage. And when delaminated glass breaks, there is a greater risk of both panes shattering at the same time.


drainage-to-avoid-glass-delamination

AVOIDING GLASS DELAMINATION

The key to avoiding glass delamination problems in your exterior glass balustrade installation is to create water drainage points from inside the channel, to prevent water pooling and subsequent glass immersion. Although most channels are fitted with a top bead and/or gasket that lies flush with the glass, these are to prevent debris from getting inside the channel, they are not watertight.

The best place to create drainage points for the channel is at the end of the channel, and there are two ways of doing this depending on whether you are finishing the channel against a fixed feature or not. If the channel ends against a wall or other feature, leave a 2mm gap between the channel and the wall and this will enable water to drain out sideways. Alternatively, if you are fitting an end cap to the channel, drilling a 7mm+ hole into the end cap will provide water drainage. Any smaller than 7mm and you run the risk of the hole ‘self-sealing’ over time. It is also possible to drill drainage holes into the channel itself, one hole every two-metres should create sufficient drainage points to keep the channel clear of water. When drilling into the channel or end cap, it’s important to ensure that the drill holes sit below the bottom of the glass panel, to avoid water immersion.

If your balustrade is in an area prone to water exposure and you wish to protect the top of the glass from delamination, a handrail can be used to protect the top edge of the glass from the elements. For a subtler finish, try using a C-strip handrail. As well as keeping your interlayer dry, handrail creates an extra line of defense in the event of a pane of glass being broken.

Complimenting Contemporary Architecture with Beautiful Balustrade


VISTApedia logo 03

COMPLIMENTING CONTEMPORARY ARCHITECTURE

WITH BEAUTIFUL BALUSTRADE


contemporary-achitecture

CONTEMPORARY ARCHITECTURE

‘Contemporary architecture’ is a term often used interchangeably with ‘modern architecture’, although in real terms these are two very different things. Modern architecture refers to a period in history around 1920-1960, an architectural movement that celebrated functionalism and minimalism, the rejection of ornament. Contemporary architecture on the other hand, is very much about embracing the evolutionary and every changing trends in building design, taking into account modern lifestyles, the availability of new materials, construction techniques and environmental considerations.

Today, contemporary architecture has to address our densifying population, which often involves creating space-efficient dwellings within confined plots; with outside space, plenty of natural light and complete privacy. Modular construction and prefabricated homes are defining features of contemporary architecture, since they facilitate speedy and cost-efficient construction. Balconies create additional outside space whilst skylights and glass privacy screening inside and out allow light to pass through the building without making it feel like a ‘goldfish bowl’. Segmented open plan spaces are another trend within contemporary architecture, maximizing the use of interior space while letting the building to flow in a way that enhances modern-day living.

These architectural trends can be complimented with the use of a monochromatic colour palette which visually tricks the eye, giving the impression of negative space to make a building appear larger, or enhance a modular design where starkly contrasting shades produce a confident visual statement.


contemporary-achitecture-03

contemporary balustrade

In keeping with contemporary architectural trends, the use of frameless glass balustrade on contemporary structures is prominent. Glass as a material meets the needs of contemporary architecture in multiple ways, providing privacy screening that allows light to penetrate both internally and externally – and with modern glass strengthening techniques and technologically advanced balustrade systems, these practical and beautiful architectural elements also serve as safety features. In fact, in most areas glass balustrade can be installed without posts or handrails and still meet the strictest of building regulations, meaning that the days of compromising on aesthetics to achieve functionality are pretty much over.


contemporary-achitecture-02

COMPLIMENTARY architecture & BALUSTRADE

Frameless glass balustrade can either compliment, or blend into architectural design. With no posts or handrail glass can serve as an ‘invisible’ safety barrier which is achieved to greatest effect when the balustrade channel is sunken below floor level. Of course, this requires a fully adjustable balustrade system that allows for adjustment of the glass within the channel, which can be difficult to remove to adjust once fitted below floor level, but this is no obstacle today with fully adjustable balustrade systems taking the market by storm.

Alternatively, contemporary buildings today often celebrate the architectural quality of glass features, which are used to enhance the overall design. In these instances, choosing the right glass as well as the right balustrade channel can have a huge impact on the completed aesthetic appeal, with continuity of textures and colours being of paramount consideration.


contemporary-achitecture-04

POSIglaze CONTEMPORARY BLACK CHANNEL

In 2019 Pure Vista launched the first contemporary black brushed balustrade channel, an innovative alternative to traditional metallic finishes. Black channel is the perfect complement to a monochromatic colour scheme creating complete synergy between the different structural elements of building design.

Black dye is applied to the POSIglaze aluminum channel during the anodising process, which is carried out to 25 microns, marine-grade protection for a long-lasting finish both internally and externally. Pure Vista’s POSIglaze system is one of the most adjustable systems on the market, using patented screw-clamp technology that has a 4-degree adjustment capability on the glass within a fixed channel. Depending on the glass type and configuration, POSIglaze can achieve up to a 1.50kN loading capacity making it suitable for installations across the market spectrum, from domestic to commercial.

Preventing Water Ingress on a Balustrade Installation


VISTApedia logo 03

PREVENTING WATER INGRESS

ON AN EXTERIOR BALUSTRADE INSTALLATION


water-ingress-diagram

WHAT IS WATER INGRESS?

Water ingress is when water makes its way into the fabric of a building, be that through the roof from a missing tile for example, cracked wall render, poorly fitted windows or in places where the building has been modified and not properly resealed. Whatever the cause, the consequences can be severe and often worsen if left untreated. Signs that you have a water ingress problem in your home include damp patches appearing on walls or ceilings, mold growth and dripping or leaking water. The earlier these signs are addressed, the easier they tend to be to repair but of course the best way to keep your home safe from water ingress is to take appropriate measures to protect against it in the first place.


water-ingress-diagram

WHY ARE FLAT ROOFS PRONE TO WATER INGRESS?

Flat roofs are a particular weakness in respect to water ingress because they are far more prone to water pooling than pitched roofs. Ideally, your flat roof will be slightly pitched to allow for water runoff and so long as the roof has rainwater outlets, is properly maintained and kept clear of debris, you shouldn’t experience water pooling. In a perfect world, drainage of a balcony will have been drawn up and implemented prior to the installation of a balustrade. However, we know this isn’t always the case and can cause issues for installers. If water pooling does begin to occur on your flat roof, the water will find the weakest point of waterproofing to permeate, which could be through joins or fixings, flushing or damaged membrane. Once you have water ingression through one of these infiltration points, water damage begins to occur and the situation can escalate rapidly, causing damp patches internally, mold or leakages.


water-ingress-diagram

HOW TO WATERPROOF A BALCONY

In order to prevent water ingress, the are two main things to consider when installing a new flat roof or balcony on a property; firstly, how and where will the water drain off the roof (to avoid water pooling) and secondly how to ensure that all the potential water infiltration points are properly sealed. Water drainage can be achieved with a slight pitch on the roof carrying rainwater towards defined outlets such as drainage channels under your balustrade. If rainwater can flow off the flat roof, water infiltration points are much less likely to develop. Then for every corner, join, seam and bolt hole there needs to be a robust waterproofing solution applied; depending on the location this can be achieved with the use of appropriate sealant, butyl tape or bituminous paint.

balcony-seal-diagram

Pure Vista Balcony Seal®

The installation of a balustrade system on top of a flat roof inevitably creates potential weak points for water infiltration. To mitigate this, Pure Vista have created BALCONYseal®, a revolutionary product that provides a solution to both water drainage and waterproofing on a balcony. Currently this product is available for use with Pure Vista’s POSIglaze and SPIG-LITEadvanced balustrade systems. It comprises of drain blocks that sit underneath the balustrade channel. Notches on the top side of the drain blocks locate into the rebates of the channel or spigot, locking it into position before the system is bolt-fixed to the substrate through each drain block. The gaps between the drain blocks are your water drainage channels. The drain blocks are subsequently filled with sealant to create a fully waterproofed balustrade installation.
