Invisio® Structural Glazing System

Frameless Structural Glazing

Invisio is a thermally broken structural glazing system, offering a range of fixing details designed for modern architectural projects.

Fully tested for thermal performance and weather resistance, the complete system provides architects and specifiers with proven performance calculations. Invisio was a Jury Winner in both the Archello Awards 2024 Window Frame of the Year and For the Planet categories.

Designed by the IQ team, its fixing details are concealed within the surrounding building finishes, creating a frameless appearance. Installation and glass replacement are also considered to minimise disruption where replacement is required.

Acoustic performance can be tailored through different insulated glass unit (IGU) configurations, including specialist acoustic laminated glass, to help reduce external noise transmission. Achievable performance depends on the glass specification and project requirements.

Applications include frameless glass walls and roofs, structural glass floors and glass boxes.

The CAD Details for the Invisio System are available to request here. 

The Next Evolution: Invisio+

Invisio+ is the next generation of thermally broken structural glazing fixing technology, accommodating deeper glass units, triple glazing and advanced configurations for demanding thermal, acoustic and environmental requirements.

Fully tested at architectural scale, it achieves a verified Uw value of 0.5895 W/m²K with a Ug 0.7 W/m²K triple-glazed unit. Tested on a 3m × 6m assembly, it accommodates structural glass panels up to 6m tall without internal mullions. Its profiles use 100% post-consumer recycled aluminium, with an embodied carbon of 0.89 kgCO?/kg.
