Structural Glazing - IQ Glass International

Structural Glass and Glazing

The unmatched versatility of structural glass lies in its ability to create completely frameless glass installations on a large scale with little to no restrictions on size, shape, or structure.

Our years of experience designing and installing glass as a structural element have forged our expertise in providing frameless glass solutions that address architects’ main concerns with bespoke structural glass.

Some of the applications structural glazing can be utilised within include, but aren’t limited to glass-walled swimming pools, double-height façade designs, frameless glass walls, structural glass roofs, glass box extensions, oriel windows, frameless windows, glass floors, and minimalist glass links.

Structural Glazing Systems

Our in-house developed structural glazing system, Invisio, is the UK’s first thermally broken structural glazing system, which we now install all over the world. Designed with an inbuilt thermal break, Invisio systems achieve high levels of thermal insulation, ensuring that the glass is not a source of heat loss.

With pre-tested scenarios, we are able to provide standard testing data as well as design details, reaching far beyond the possibilities of traditional steel angle systems.

Most importantly, the Invisio system grants architects the freedom to create entirely bespoke structural glass installations with confidence, thanks to a thoroughly tested and validated system.

Structural Glass Wall

Using our Inviso thermally broken structural glazing system, IQ can design entire walls of glass using panes of structural glazing and offers the option to incorporate opening elements such as a slim sliding door. 

The neat silicone joins allows the structural glass wall to offer panoramic views of the outdoors whilst allowing in a vast amount of natural light.

Structural Roof Glazing

Glass roofs that utilise panes of structural glazing are an excellent way to maximise natural light and give an indoor space a strong bond with the outdoors. 

Support need for structural roof glazing will depend on the size of the roof and panes used. Glass beams and fins can be used, or steel T sections may be better suited depending on the project. 

Similarly to all structural glazing solutions, any performance values will need to be calculated on a project-by-project basis.


Structural Glass Façade

With completed glass façade projects all over the UK and internationally, we are the unparalleled leaders in bespoke glass façade design.

Our vast collections of completed projects have included glass facades that feature curved glass, screen printed glass, shaped glazing, heated and privacy glazing.

All our structural glass projects are delivered and installed to tight programs and in some of the most challenging site locations in the world.

To create a bespoke structural glass façade we like to start at the beginning and work with you, offering a consultative service, to create a bespoke glass façade design in keeping with your design intent, budget and performance requirements.

Structural Glass Floor

Structural glazing can be utilised for a wide variety of glass floor options. Some applications include internal glass floors that provide views between two different floors of the building or to get light into basement spaces. 

Walk on glass floors must be specified with structural glazing for it to be safe to walk over, this will include a toughened and laminated out pane, as well as inner is there is a living space below. 

Curved Structural Glazing

Incorporating curved glass into structural glazing solutions offers clearer views of the surrounding with not even a silicone join disrupting the views. 

This also means that the flow of natural light is completely uninterrupted. Curved structural glazing is most used in glass walls or for internal glass courtyards but can be used in a wide variety of applications.

Structural Glass Balustrade

IQ use structural glazing to manufacture our frameless glass balustrades, with two panes of toughened glass laminated together using a strengthening interlayer. 

Toughened glass is five times stronger than float glass making it less likely to break upon impact, and in the event of breakage, the interlayer helps to keep the balustrade upright.

This means that the safety barrier will still provide a certain level of protection, even when broken.
