IQ’s unique Invisio system - the UK’s first thermally broken structural glazing system - enables architects to work with unrivalled flexibility when designing bespoke structural glass solutions.

Structural glass products range from eaves windows to structural glass bridges, however, frameless shaped windows are arguably the most sought-after structural glazing solutions. This is because completely frameless glass installations are not hindered by limitations experienced with other systems.

The freedom afforded when specifying the Invisio system means that a wide variety of shapes of structural glass windows can be engineered. IQ’s frameless picture windows require absolutely no visible frame or fixings, can be specified in bespoke shapes and are beneficial for multiple reasons.

Not only can a frameless window be specified in specialist large sizes, but arched heads, angled bases, cut out notches and curved window solutions are achievable, making them the perfect option for contemporary designs.

Moreover, rooms with frameless shaped windows are seamlessly merged with the external environment, resulting in uninterrupted views of the surroundings and an increased the perceived size of the space. Natural light is welcomed into any home with these bespoke windows, transforming poorly lit rooms into more habitable spaces to relax and appreciate both the internal and external environments.

Gable end structural glass windows are also extremely popular amongst clients seeking to create top floors engulfed with natural light. Gable end windows are extremely popular for loft conversion projects, following the structure of any roof shape or size.

When paired with other slim framed window systems, such as sliding doors or entire walls of glass, an oversized statement window design can be achieved.

The inbuilt, thermally broken nature of the Invisio system ensures comfortable living temperatures are achieved all year round, by removing the common thermal bridging issue of structural glass – this is an aspect of IQ’s structural glass windows that is unmatched by other structural glazing solutions on the market.  

The list of specification options for shaped structural glass windows is seemingly endless, with triple glazing, curved, low iron glass, bird protection glass and acoustic reduction glass, to name a few.

Acoustic reduction glass is an ideal extra for those looking to reduce external noise in urban areas, whilst decorative finishes can be achieved by including coloured interlayers or sandblasted glass in any desired pattern. 

Solar control coatings are also available for frameless shaped windows and are recommended for south facing windows to reduce solar gain. Furthermore, IQ Glass are able to incorporate laminated and thicker glass panels where required, whilst maintaining a completely frameless design.
