Triple sheet laminated glass

What is Laminated Glass?

Laminated glass is one of the most popular products on the market—and for good reason. With its superior strength, variety of thicknesses and layers, and endless decorative options, laminated glass is the perfect choice for safety-first and decorative uses in all kinds of commercial and domestic applications.

That said, laminated safety glass isn’t for everyone. To help you decide whether this type of glass product is best for your project, we’ve put together a short guide. Read on as we explain some of the key features, including when to use it and how it differs from toughened glass.

How is laminated glass made?

Laminated glass is made by adhering two or more regular sheets of glass with a flexible PVB (polyvinyl butyl) interlayer. This is achieved by a heating and bonding process that conjoins the different layers to form a single glass sheet.

The main benefit of this type of glass is its strength. It is widely used for safety and security purposes, to the point where you’ll often hear it referred to as “laminated safety glass”. Because of the VB layers bonded to the glass, if the glass is somehow broken, it will still hold in place. As an added bonus, the PVB interlayer makes the glass hard to breach, even when broken.

At our glass processing plant in Portsmouth, we create laminated glass sheets using either PVB or EVA (ethylene-vinyl acetate) as the interlayer. Our technicians heat and compress the layers with a specialist machine that bonds the glass to the PVB or EVA—like a sandwich that turns into a toastie.

The beauty of this process is that it works for a variety of glass thicknesses and layers. This means we can create laminated glass for all kinds of applications, from glass partition walls and balustrades to glass staircases and floors.

How does it differ from toughened glass?

Laminated and toughened glass are both popular choices for safety. Both can be cut, shaped, and drilled (prior to toughening) to suit all kinds of safety-first applications. But toughened glass is processed differently, and as such, it behaves differently when broken.

Toughened safety glass is heat-treated not only for strength, but to ensure that, if broken, the glass shatters into extremely small pieces. UK safety standards for toughened glass dictate that the glass should break into parts no more than 5mm wide. This ensures that the small parts do not cause serious injury, unlike large shards.

Laminated safety glass is just as robust as toughened glass. However, it does not have to undergo a “toughening” process in the manufacturing stage. Instead, the PVB interlayer bonds the glass together, holding the panel in place when broken and preventing serious injury.

Laminated and toughened glass can also be combined for a maximum-strength panel. At abc Glass, we do this by laminating the glass “sandwich” in the normal way, but also using toughened safety glass either side of the PVB.

Popular uses for laminated safety glass

Frosted glass balustrades with handrail

The process of laminating glass has been widely used for safety applications ever since Henry Ford started adding it to Ford car windscreens in 1919. Nowadays, laminated windscreens are standard fitment for vehicles all over the world.

Laminated glass stair treads

As for domestic or commercial design uses, laminated glass crops up in virtually every application where safety is a priority: balustrades for balconies, swimming pools, and staircases; glass flooring; glass stair treads; glass canopies; glass partition walls; and windows and security doors. This is a testament not only to the strength of this product, but also its versatility.

Decorative mesh glass

Laminating glass with coloured, fabric or mesh interlayers also offers designers a chance to get creative. Coloured glass (usually blue, green, or grey) is popular with colour added either by using coloured glass panels or by adding a tinted PVB layer. We often recommend the latter, as a coloured interlayer provides many more colour and tint options than a regular glass panel.

Blue safety glass balustrades

Designers can also use frosting or sandblasting for a decorative effect. This comes in the form of a sandblasted PVB interlayer, which creates a layer of privacy in spaces such as bathrooms, private offices, or hallways.

Taking the decorative laminated glass theme further, our technicians can also add decorative mesh or fabric interlayers to accommodate an almost unlimited range of striking effects. This can take the form of swirling patterns, geometric shapes, nature-like textures, and more. This relatively new product allows designers to use glass panels to striking effect. Wall cladding, shower screens and glass partitions are just a few of the possible applications for this exciting product.

Examples of decorative mesh inter-layered glass

If you’re thinking about using laminated safety glass for your next project, abc Glass can help. We specialise in cutting and shaping custom laminated glass panels to suit all kinds of spaces, from glass balconies and floors to glass doors and partition walls. We also offer a decorated laminated glass service, with many patterns and textures to choose from.

A Short Guide to Using Sandblasted Glass in Commercial Spaces

Sandblasted (or frosted) glass is one of the most reliably popular glass types in the commercial design realm. It offers commercial interior designers the chance to get creative and make a real impact through glass, whether in a hotel, office, spa, retail spaces, or any other public venue.

In this article, we’ll list some of the many artistic and creative touches made possible by sandblasted glass panels. Whether you’re looking to convey a message with a frosted glass sign or add a layer of privacy to a glass-enclosed space, sandblasting offers a stylish and cost-effective solution.

What is sandblasting?

Producing frosted glass

Sandblasting involves adding a “frosted finish” to a standard, toughened, or fire-resistant glass panel. The process works by firing sand particles at the surface of the glass to roughen the surface, creating an opaque frosted finish. The more passes made using the sandblaster, the more frosted the glass becomes.  By masking off areas of the glass it is possible to create patterns, add logos or text to the glass, giving a wide range of design possibilities.

Next, the sandblasted glass is treated with ClearShield, a special polymeric coating. This helps protect the frosted glass from finger marks and dirt. As a rule, we always recommend a ClearShield coating. Unlike frosted window films, which consist of a self-adhesive film applied to the glass, sandblasting is permanent, weather proof and will not wear.

External frosted glass balustrades

As you’d expect, the transparency of sandblasted glass varies widely depending on how it’s processed. When looking through a lightly frosted panels, it should still be possible to see through the glass and make out colours and shapes. At the other end other scale, a strongly sandblasted panel effectively blocks out any view through the glass, with only bright light visible.

For commercial use, there are three main types of frosted glass:

Frosted glass signs – Ideal for corporate or commercial spaces where a company logo or branding must be displayed. Instead of fully sandblasting the glass, our technicians mask off parts of the glass to allow lettering and graphics to be permanently etched into the panel – otherwise known as partial sandblasting.

Patterned sandblasted glass – This adds a decorative touch to otherwise-boring glass office partitions and balustrades. Using patterns or motifs, we can customize your frosted glass to suit the mood or function of the space. Again, this is achieved by masking off the glass during the sandblasting process, leaving a striking frosted glass pattern.

Fully sandblasted glass – A belt-and-braces option for spaces that demand privacy, such as meeting rooms, but also require a good amount of light. Full sandblasting is also advised for glass floors and stairs, as it provides modesty while allowing light to penetrate below.

Frosted glass is just one example of the combination of human craft and technological wizardry that we use every day in our Portsmouth glass processing HQ. If you have any questions about our glass frosting service, or indeed any other glass processing service or glass products, please contact us

Shower enclosure glass treated with ClearShield

Why You Should Invest In Clearshield Glass

ClearShield is a special polymeric coating applied to glass surfaces such as shower enclosures and balustrades. Developed by manufacturers Ritec, it consists of a clear liquid resin that resists the typical blights found in moisture-heavy glass areas: limescale, dirt, stains, and so on.

When the resin is applied, water beads and runs off much more quickly. This is because the glass itself is made very slippery – almost nothing undesirable will stick to it. The upshot is that ClearShield keeps your glass looking as good as new for much longer. At abc Glass, we know from our clients just how much better ClearShield-coated glass is compared to equivalent glass without a special coating.

Depiction of glass treated with ClearShield glass coating

Why use ClearShield for shower glass?

ClearShield solves some of the most common cosmetic and hygienic issues with shower glass. These start with cosmetic benefits such as preventing water marks and generally keeping the shower easier to clean.

Another factor is hygiene: the glass coating prevents the build-up of dirt, limescale, and contaminants that tend to occur with regular use of a shower enclosure. By preventing these contaminates from sticking to the glass, ClearShield also helps to slow the growth of bacteria.

Luxury frameless shower enclosure

High-end frameless showers – typically with large expanses of glass – are especially suited to ClearShield. After all, if you’re going to splash out on a fully-fledged luxury glass shower enclosure, why not make extra-sure of its sparkle by requesting a stain-and-dirt-resistant coating?

Whatever it’s used for, Clearshield greatly reduces the amount of cleaning in your shower area. The glass panels will stay cleaner, clearer, and more pristine for much longer, without the need for tedious regular cleaning.

What other applications does ClearShield suit?

Aside from shower glass, ClearShield can be used virtually anywhere where glass is exposed to moisture, whether inside or outside. A good example is balustrades, such as on balconies or as pool fences: Although not subject to as much use as a shower enclosure, the likelihood of dirt, limescale, or bacteria from collecting is just as high.

Large balcony with stainless steel and glass balustrade

Separately, if you plan to use ultra-clear low iron glass for any application, a ClearShield coating is recommended. For one thing, it will lessen the burden of cleaning and maintenance. Why invest in crystal-clear low iron glass if it stains easily?

Another point to consider is whether your balustrade glass is being installed on the first floor or higher. The higher the floor, the more difficult your glass may be to access. This is especially pertinent for properties near the coast, where outside glass is more easily subject to damage from salt and the elements.

As for our sandblasted glass, we include a ClearShield coating as standard and at no extra cost. This is due to sandblasted glass being highly susceptible to grease.

Can I apply a ClearShield coating myself?

While it is possible to buy a home application kit for treating or topping up glass coating, for best results we recommend using a professional service. At abc Glass, we specialize in producing glass sheets with ClearShield protection for frameless showers, balustrades, pool fencing and many applications. What’s more, our glass technicians have been trained by Ritec, the makers of ClearShield, which guarantees that your coating will be applied to the highest standards.

Laminated Glass Could Be Perfect for Your Next Project

What makes laminated glass such a popular choice for commercial and domestic spaces? Put simply, it comes down to two core features: safety and style.

In this article, we explore what makes laminated glass so robust, and why designers and architects trust it for a wide range of safety applications. We’ll also look at how to add a decorative touch to laminated glass to ensure your interior or exterior space excels on a stylistic level.

Why is laminated glass used for safety applications?

You sometimes hear laminated glass referred to as “safety glass”. The safety aspect comes from the laminating process used to give the glass structural integrity. When a laminated panel breaks, the glass keeps its shape – whereas standard glass may shatter into hundreds of shards. All laminated glass sold in the UK must meet these requirements, labelled the EN 14449 safety standard.

To understand why laminated glass is so robust, look at its structure. Laminated glass consists of three or more bonded layers, the most important of which is a plastic interlayer. This is usually made from polyvinyl butyl (PVB) or ethylene-vinyl acetate (EVA) layer. At abc Glass, we stock float glass in 4mm to 19mm sizes and this allows us to produce laminated glass in thicknesses to suit projects ranging from internal glazing to laminated glass floors.

What other benefits does laminated glass offer?

Aside from safety, laminated glass offers several key benefits for both domestic and commercial use. The first is protection from solar and UV rays – up to 99%, in fact, compared to just 65% for tempered glass. Second, laminated glass is better at blocking out noise, so much so that it’s used on professional recording studios.

Third, there’s the fire-proof aspect of laminated glass. While not quite as high performing as fire rated glass (which uses a gel interlayer instead of plastic), laminated glass is nonetheless recommended by engineers as “effective… for  architects and building occupants.” The fourth advantage is one that will hopefully never be needed: laminated glass is bullet-proof.

Last, but not least, is decorative laminated glass. Our glass technicians can create beautiful patterns of almost any texture and hue, all using modern digital printing methods. We can also add a sandblasted effect to your laminated glass, as well as custom back painting in any RAL colour.

What are the best uses for laminated glass?

Examples of laminated glass products

  • Balustrades and balconies – We’ve supplied laminated glass panels for dozens of clients’ balconies and balustrades. Many opt for frosted or decorative glass for a touch of privacy. No matter the style, laminated glass ensures safety while you enjoy the views.
  • Internal glass balustrades – It’s not just balconies where laminated safety glass is needed. Internal balustrades, such as those used in staircases and landings, call for robust safety glass.
  • Glass floors and stairs – Designers can liven up the most mundane floor or staircase area with laminated glass. From spiral glass stair treads to glass balcony floors, glass can be used to bring a wow-facture – so long as you’re not scared of heights.
  • Interior glass partitions and doors – Last month we explored why glass office partitions are going nowhere after the pandemic ends. Laminated glass partitions and doors offer extraordinary strength as well as style – ideal for workspaces as well as the home.
  • Glass shelves and table tops – These sleek units are commonplace in shopping malls, hotels, and other luxury spaces. But with recent trends towards home bars, glass bathroom counters, and glass table tops, designers of home interiors are starting to jump on the bandwagon. Glass shelving and tops can also be produced from thick toughened safety glass.

Waste cullet glass ready for collection and recycling at abc Glass Processing

How We’ve Reduced Glass Waste by Investing in Technology

At abc Glass’s Portsmouth HQ, we process thousands of square metres of float glass every year. But like any manufacturer operating on this scale, we’ve had to solve some practical and environmental challenges along the way.

Waste cullet glass ready for collection and recycling at abc Glass Processing

The first challenge relates to our manufacturing methods: How can we use the most efficient technology and processes to reduce consumption and waste? The second challenge is simpler: What to do with the waste glass?

In this article, we’ll show how abc Glass has invested in better glass processing tech to boost efficiency and reduce waste. We’ll also explore how several of our partner companies are leading the charge in glass recycling schemes to help reduce the glass industry’s carbon footprint.

More efficiency = less waste

Most of our glass processing relies on sophisticated glass-cutting machines. Over the last 20 years, we have invested heavily in cutting-edge digital machinery to reduce waste, increase accuracy, and perfect the quality and tolerance of our glass products.

Computerised automated glass cutting line at abc Glass Processing

One such machine is our computer-controlled and -automated glass cutting lines (seen here in this factory tour video). This extraordinary kit calculates the most efficient use of glass by digitally laying out separate glass orders across a single 4-metre sheet of float glass. The aim is to minimise waste by intelligently maximising the amount of glass used on every sheet. We simply couldn’t achieve this level of waste-reduction without help from automation.

Several other computer-controlled machines help to reduce our glass waste. These include three high-tech CNC (Computerised Numerical Cutting) machines, which we rely on daily to create extremely complex and accurate glass shapes. CNC machines can be programmed by our technicians. Such easy-to-use technology drives accuracy and reduces waste as we process glass for customers.

How is our waste glass recycled?

In a perfect world, improved efficiencies in the manufacturing process would result in no glass waste at all. However, despite all our progress, abc Glass still ends up with a small amount of waste each day. Rather than consign this glass to landfill, we have launched several partnerships with outside companies who specialise in recycling glass waste.

One of these companies, Saint-Gobain, recycles around 55,000 tonnes of glass waste each year. A small fraction of this glass consists of waste from the abc Glass factory – we collect the off-cuts (or “cullets”) from our glass processing machines and store them in large bags for collection. Once delivered to recycling plants, the cullets are sorted using smart digital machines before being processed into brand-new float glass.

Last year we recycled over 300 tonnes of waste glass through various Cullet Return Schemes. This works out to 25 tonnes a month – a figure we are proud of. The vast majority of this glass waste comes from off-cuts of float, coated, and mirror glass sheets used to process our wide range of glass products.

If you have any questions about glass recycling, or want to know more about how we’re improving our carbon footprint through efficient processes, please get in touch. Our glass processing experts will also be happy to lend advice on your next project and explain how our range of services could help.

What is Decorative Laminated Glass?

We hear this question a lot from our clients. And no wonder: decorative laminated glass is growing in popularity year-on-year. By combining the toughness of laminated glass with the beauty of customised patterns, textures and colours, decorated laminated glass offers a robust yet stylish solution for livening up a home or commercial interior.

In this article, we’ll show you how decorative laminated glass is actually made in our Portsmouth factory. We’ll also explore the glass’s unique properties and reveal how laminated glass can be decorated with a choice of hundreds of artistic features. Finally, we’ll run through some of the best uses for decorative glass both indoors and outdoors.

How is decorative laminated glass made?

At abc Glass, our process of making decorative laminated glass differs only slightly from that of standard laminated glass. The key thing to remember is the extra mesh or fabric “interlayer” sheet added during the laminating process. This sheet, made from either polyvinyl butyl (PVB) or ethylene-vinyl acetate (EVA), can be decorated in a myriad of ways, as we’ll explore later.

The step-by-step process is simple. First, our technicians insert the decorative interlayer between two toughened or untoughened glass sheets. Our state of the art glass laminating machine bonds the three layers together to form the final product. And bingo: your decorative laminated glass is ready.

Tougher stuff

 

example of shattered laminated glass

 

To the untrained eye, decorative laminated glass may seem a purely stylistic choice. But as we’ve seen, it’s also an extremely robust product. In the UK, all decorative laminated glass must meet EN 14449 safety standards to be considered legal. This ensures that, when shattered, the glass sheet keeps its original form, displaying a trademark “spiderweb” crack pattern. Contrast this with untreated regular glass, which breaks into a handful of unsafe sharp shards – disastrous in the event of breakage or a fire.

Further benefits of decorative laminated glass include better sound insulation as well as blocking out harmful UV rays. What’s not to like?

A layer of personality

 

Decorative laminated glass examples

 

The most exciting aspect of decorative glass is, of course, the decoration. You can add an incredible array of patterns and colours to your mesh or fabric interlayer. Our website showcases just a few of the patterns we offer, from cool metallic to sandy textures.

Putting decorative glass to use

In theory, anywhere that normal laminated glass is found can be kitted out with decorative glass. Popular uses include for glass balconies, glass partitions, glass balustrades, glass table tops and shelves, glass staircases, glass flooring, frameless glass shower enclosures, and much more.

Bear in mind, however, that certain spaces may not lend themselves to added decoration. In some cases a simple clear or frosted laminated glass sheet will work better – far be it from us to judge!

Before ordering any decorative laminated glass, we recommend speaking to one of our in-house glass experts. We’ll explain the process for processing and supplying glass for your specifications and show you the many patterns and colour options available.

Fire rated glass in an office environment

What is Fire Rated Glass?

When designing a building, architects must always plan for the worst. An out-of-control fire can destroy buildings and put lives at risk – which makes fire rated glass a great solution both inside and outside a building.

Fire rated glass

Fire rated glass (also known as fire-resistant glass) is a specialist product that offers a robust barrier against heat, flames, and smoke. Unlike regular or toughened glass, its fire resistance is determined by a controlled test. But what else separates fire rated glass from its cheaper, but less safe, cousins? Let’s explore.

A place of greater safety

Fire rated glass in an office environment

With its ingenious design (see next section), fire rated glass can withstand heat in excess of 800°C whilst keeping flames and smoke at bay. A matter of life and death, in other words.

Building regulations are strict when it comes to fire safety-specific glass. As a legal requirement, all fire rated glass must pass a Fire Resistance Test to be considered usable. This test is used to measure the performance of a glass panel at different levels of fire intensity.

Fire Resistance Tests look for two kinds of performance. These are:

  1. Integrity – The length of time that the glass remains intact whilst keeping out flames and smoke. This is indicated in the rating itself – E30 means the glass keeps its integrity for at least 30 minutes.
  2. Insulation – The level of heat protection offered by the glass. The non-fire side of the glass should stay at a safe temperature for the length of time indicated in the rating.

Layer upon layer

Fire rated glass comes in two types: laminated and non-laminated. The secret to laminated fire rated glass is found in its intumescent layer. This baffling word has a rather simple meaning: a substance that expands when it heats up.

Laminated fire rated glass uses multiple layers of toughened glass sheets with an intumescent gel layer in between. (Non-laminated versions use just a single sheet, which is toughened after the process.) When a fire breaks out, the first glass sheet will shatter, activating the first intumescent layer. This causes the gel to expand, creating a more effective barrier against flames and smoke.

These individual layers are extraordinarily thin. Indeed, abc Glass’s stock fire rated glass boasts a thickness of only 7mm. But for the glass to work, it must be installed within a fire-resistant frame or surround. This not only secures the glass but prevents the intumescent gel from leaking out at the perimeter. Manufacturers install a spacer around the edge of the glass to prevent such a mishap.

What fire rated glass do we offer?

At abc Glass, our expertise lies in cutting and shaping laminated fire rated glass. We do not manufacture the glass itself, nor the framing system. However, the extent to which we can process fire safety glass for your specific requirements is nearly unlimited. Our technicians can drill, polish, bevel, and paint your fire rated glass, as well as shape it to precise measurements using our state-of-the-art CNC machinery.

Our go-to fire rated glass is Pyrobelite 7, a popular product that meets the European standard (BS EN 13501-2). This popular glass is kept in stock all year round and is by far our best-selling fire-resistant glass. We can also order in other types of fire rated glass at a 2-3 week lead time. These include thicker glass sheets better suited to internal partitions and balustrades.

If you’re interested in our fire rated glass services, feel free to contact our friendly and knowledgeable team. We look forward to answering any questions you may have about fire-resistant glass and to discuss your next project.

Electronic windows for the home of the future

Is Smart Glass the Future of Home Design?

With bad news arriving each day, it’s easy to forget that we live in an age of innovation. From driverless cars to robots that deliver food, dozens of exciting products are poised to enter the market in the coming years. The home design world is no different, with new glass technology posed to transform our homes.

So, what are these technological wonders that await? In this article, we pick out the most exciting glass products set to enter our homes over the next 10 to 20 years. What’s more, many of these innovations promise to save us money while reducing our carbon footprint.

 

“Chameleon” glass

Colour changing glass

Colour-changing glass is set to revolutionise how we think about interior colour schemes. Scientists in the US have made astonishing breakthroughs in this particular field, with early samples yielding amazing results. The idea is simple: by flicking a switch, molecules bounce around in the glass to turn into a new colour.

Does this new tech require lot of electricity to make work? Quite the opposite. The amount of energy used to switch from colour to colour is minuscule. Indeed, 100 panes of colour-changing glass uses the same energy of an  incandescent lamp for this simple task.

 

Smart glass for your appliances

Kitchen of the future with appliance touch screen

Smart glass is coming soon to a fridge near you. Soon enough, current features such ice dispensers and digital clock faces will look rather quaint by comparison. Future fridges will instead boast a plethora of integrated gadgets to make life that much easier. Chief among them is a tablet-style smart glass screen built into the face – great for flicking through recipes, checking the family calendar or playing music.

 

Windows, but not as we know it

Electronic windows for the home of the future

Glass windows aren’t supposed to do anything complicated. For most homeowners, letting in light whilst keeping out noise and foul weather is all that’s needed. Researchers, however, have spotted a potential new benefit for glass windows: helping to saving the planet. Solar panel collecting windows use the sun’s energy to charge nearby devices, such as smart speakers and TVs.

By 2040, most homes will have obscure glass that deflects up to 98% of outside light. A great substitute for blinds, obscure glass also removes the need for expensive air-conditioning costs. Homeowners will have smart-home systems installed to adjust their window’s light-to-dark settings, whether at home or out and about. Smart glass apps will soon be commonplace, just as modern gadgets like Hive and Ring let us remotely change our home settings.

 

A frosty reception

Frosted glass shower screen with smart technology

Frosted glass is an always-popular choice, especially in the bathroom. However, users are currently restricted to a binary choice: frosted or clear? This is all set to change with smart glass. With the flick of a switch, you’ll be able to enter “privacy mode” by changing your clear glass shower screen to frosted – and back again. Shower areas will also boast waterproof touch screens to adjust the controls, from water flow and timings to temperature.

Unfortunately, at least some of these exciting glass innovations are still very much in the future. In the meantime, abc Glass offers a market-leading range of services to create inspirational glass doors, splashbacks, mirrors, and much more. Get in touch to discuss your requirements with our team, who are working remotely until the Covid-19 restrictions are relaxed.
