Bespoke structural glass systems in the UK

There are many ways to implement structural glazing, with exterior curtain walling and shopfronts being some of the most popular. Durable yet transparent structural glass maintains the security of your building while creating a beautiful aesthetic and increasing the amount of natural light.

Or how about walk-on glass floors, constructed from 33mm thick toughened glass supported by a framework of stainless steel? Widely used in commercial and residential buildings alike, a glass floor provides a creative interior design option while also being extremely strong and completely safe.

For the ultimate elegant entranceway, your building could even have a glass atrium, with a wonderfully open structural glass roof and facades. If you like the aesthetic of glass but drastic alterations aren’t viable, glass barriers are a great alternative. With our industry knowledge behind us, we can help you to successfully design and install your ideal structural glazing system.

Curtain Walling & Shopfronts

Overview
Curtain walling systems provide the perfect solution for the external cladding of any building capable of allowing in large amounts of natural light through large expanses of clear glass. This creates a feeling of space and provides the perfect interface with the outside world, all while maintaining the safety, security, and comfort levels of the building’s internal environment for the benefit of its occupants. Our aluminium system offers both single and double-glazed options and is based around a box and plate configuration while creating a thermal barrier. Our frameless glazed system uses structural spider fixings to create seamless configurations.

Walk-on Glass Floors

Overview
We provide walk on glass floors for residential and commercial application.1.2 U-Value can be achieved using our offset double glazed system. The 33mm thick glass is supported by a stainless steel framework with glass support beam. We work closely with architects and contractors to design our systems to suit each individual project. We can also provide structural calculations and drawings to satisfy building control requirements. Framework is powder coated to any RAL colour and perimeter profile is kept to a minimum to maximise visibility of the glazing.

Atrium Glazing & Glass Barriers

Overview
Design & installed glass barriers and atrium glazing up to 3kN line load. We use a combination of toughened laminated glazing panels and our aluminium glazing shoe. We supply full structural calculations for each project. The atrium glazing can also be fire rated up to Ei60 to compartmentalise office space and escape routes. Please contact our design team for more information.

FAQs

One of the biggest benefits of structural glazing is that the lack of framing systems gives architects and designers more opportunity to create truly stunning installations of glass for their buildings. This allows a much wider scope and greater flexibility in creating a completely bespoke design.

The only factors restricting the maximum size of structural glass panels are your budget and site access limitations. The thickness of the glass will help to increase the building’s energy efficiency, with thermal technology maintaining an ambient temperature instead of trapping too much heat.

Large expanses of glass are eye-catching from the outside and offer unrivalled open views of the surrounding area from the inside. Not only does it physically increase usable interior and exterior space, but it also tricks the eye into thinking it’s even more spacious due to the flood of light.

There’s a lot of in-depth engineering involved in a successful structural glazing installation. The physical performance of each glass panel is far more important than how it looks, which is why so many calculations go into ensuring that your bespoke glazing is structurally sound.

Factors that require extensive consideration when selecting structural glass qualities include:

  • Thermal insulation

Structural glass is given a ‘Ug’ value according to the amount of thermal energy that can pass through the centre of the pane itself. The lower the value, the better the insulation; you should never go for glass with a Ug value of more than 1.2 W/m2K for structural glazing.

Th ‘Uf’ value refers to the thermal performance of the framework, while ‘PSIG’ indicates the performance of glazing spacers. These can all be combined into an overall ‘Uw’ value, sometimes referred to as simply the U value, using test methods standardised by BS EN 673:1998.

  • Acoustic reduction & fire rating

You may be familiar with seeing sonic insulation ratings in decibels, but acoustic reduction values are represented by an ‘Rw’ figure for structural glass. Decibels measure acoustic power, and hertz measure vibration frequency; both go into the calculations for Rw standardised by EN ISO 717-1.

As for fire-rated glass, it needs to be fire-tested at its full size as per the intended installation before it can be used for structural purposes. Any fixings will also need to be fire-rated. You can find out more about how fire ratings for glass work on our Fire Rated Glass Partitions & Doors page.

  • Line load & maintenance load

Since the glass is expected to bear a heavy structural load, your design must be tested to ensure that it meets all the necessary load-bearing requirements. You cannot legally install structural glass that is not fit for purpose due to the obvious safety risks, which is why prior testing is mandatory.

Vertical glass panels must be able to withstand a particular line load – like the weight of a person leaning on a glass barrier. The glass specifications and fixings must bear the appropriate load for its intended purpose. The same applies for horizontally installed panels, which must be able to bear an adequate maintenance load – such as the weight of a person accessing a roof for repairs.

Exterior walls and facades will also need to withstand a wind load of no less than 0.5kN to ensure that the structural glass won’t crack, bow, or break under the pressure of strong winds. Buildings by the coast or at high altitudes are likely to have much higher wind load requirements.
