Invisio+ Structural Glass for Commercial Projects | IQ Projects | 14th July 2026 | IQ Projects News | Latest Architectural Glazing Updates

Invisio+ is the next evolution of IQ Glass’ award-winning Invisio structural glass fixing system. Designed to accommodate deeper glass units, Invisio+ enables the inclusion of triple glazing and advanced glass configurations for high-specification architectural projects, from commercial façades and heritage refurbishments to cultural buildings, hospitality spaces and mixed-use developments.

Developed in-house by IQ Glass, Invisio+ advances the original Invisio range with improved thermal performance, greater specification flexibility and a fully tested approach to large-scale frameless structural glazing.

What is Invisio+?

Ultra-Slim. Ultra-Efficient. Ultra-Low Carbon.

Invisio+ is a thermally broken structural glazing fixing system designed to support triple-glazed structural glass at architectural scale. The value of Invisio+ lies in the engineered fixing system behind the glass, allowing large-format structural glazing to be installed with no visible framing, capping or supporting structure.

Invisio+ opens up new opportunities for expansive frameless glass where performance, visual clarity and buildability must work together. From glazed entrances and atria to glass links, roof-edge details and structural façades, Invisio+ allows ambitious glazing designs to be realised with a fully concealed fixing approach.

Structural glass has become one of the defining features of contemporary architecture, creating transparent façades, panoramic fixed glazing, frameless glass walls, eaves glazing and bespoke glazed connections between spaces. By eliminating visible framing, it allows architecture to be defined by light, proportion and uninterrupted views

The Fixing System Behind Invisio+

The fixing profile is fully concealed within the surrounding building finishes, allowing the completed installation to appear as continuous glass. A thermal break is integrated directly within the fixing, reducing thermal bridging at one of the most critical junctions in the glazing assembly while helping to maintain long-term thermal performance.

This concealed fixing approach is particularly valuable on complex projects where glazing must integrate cleanly with the surrounding building fabric, structural interfaces, internal finishes and project-specific installation requirements.

Exclusively available through IQ Glass and delivered by IQ Projects as part of complex commercial glazing packages, Invisio+ combines architectural freedom with verified thermal and structural performance, helping project teams achieve ambitious frameless designs without compromising performance, buildability or long-term reliability.

Built for Complex Project Delivery

Commercial glazing packages often involve multiple stakeholders, challenging site conditions and detailed coordination between architects, main contractors, façade consultants, structural engineers and specialist subcontractors.

Invisio+ has been developed to support this workflow by providing a tested and repeatable structural glazing system that can be considered early in the design and specification process. By establishing the glazing strategy at concept or technical design stage, project teams can better coordinate structural interfaces, surrounding finishes, access requirements and installation sequencing.

The system’s full glass removability also supports long-term serviceability, allowing individual glass panels to be replaced independently of the primary fixing system if required in the future. This helps reduce disruption during maintenance or replacement works, which is particularly valuable on high-traffic commercial, hospitality and public-sector buildings.

Product Performance at Scale

Exceptional design demands equally exceptional performance. Invisio+ has been engineered and extensively tested at architectural scale, providing architects, specifiers and contractors with verified performance data rather than theoretical calculations.

The Invisio+ profile has been designed to accommodate deeper glass units, enabling the inclusion of triple glazing and advanced glass configurations for projects with demanding thermal, acoustic and environmental performance requirements.

When used with a Ug 0.7 W/m²K triple-glazed unit, Invisio+ achieves a verified Uw value of 0.5895 W/m²K, tested on an assembly measuring 3 metres by 6 metres. Testing at this scale reflects the real demands of contemporary architecture, where large-format glazed elevations are increasingly specified across commercial, residential, hospitality and public-sector projects.

The system is capable of supporting 6-metre-tall structural glass panels with no internal mullions, enabling uninterrupted glazing with the clean, minimalist detailing expected from frameless architectural design. With the fixing system concealed within the surrounding building fabric, the façade reads externally as a seamless expanse of glass with no visible supporting structure.

Invisio+ has been developed with long-term durability, serviceability and maintenance efficiency in mind. Its full glass removability allows individual glass panels to be replaced independently of the primary fixing system, supporting future maintenance without compromising the original fixing strategy.

By combining verified performance, engineered durability and simplified maintenance, Invisio+ delivers a structural glazing solution designed not just for installation, but for decades of building performance.

Applications for Commercial Glazing Packages

From heritage renovation projects to high-specification commercial developments, Invisio+ supports a wide range of structural glazing applications where expansive frameless glass is central to the architectural vision.

By combining a concealed fixing system with verified thermal performance, Invisio+ enables project teams to deliver ambitious glazing concepts without compromising performance, efficiency or buildability.

The system is suitable for a broad range of commercial project types and glazing applications, including:

Commercial façades and glazed elevations
Cultural buildings, galleries and public spaces
Hospitality, hotel and leisure developments
Premium workplace and office projects
High-end residential developments

With the fixing system concealed within the surrounding building fabric, each application maintains the clean, uninterrupted appearance expected from frameless structural glass while delivering the performance required for modern commercial projects.

Sustainability at the Core

Exceptional thermal performance is only one part of the Invisio+ story. Sustainability is fundamental to the engineering of the system, ensuring environmental performance is considered alongside structural integrity, thermal efficiency and architectural design from the outset.

The structural fixing profiles are manufactured from 100% post-consumer recycled aluminium, achieving an embodied carbon of just 0.89 kgCOâ‚‚/kg. By reducing the carbon impact of one of the system’s primary components, Invisio+ provides a lower-carbon solution without compromising structural integrity, durability or design freedom.

Alongside its verified thermal performance, Invisio+ supports projects seeking to reduce both operational energy demand and embodied carbon. The system is also compatible with low-carbon glass substrates, offering architects, contractors and developers greater flexibility when designing and delivering buildings that respond to increasingly ambitious sustainability targets, ESG requirements and environmental performance standards.

Rather than treating sustainability as an optional feature, Invisio+ integrates environmental performance into the core of the system. The result is a structural glazing fixing system that combines minimalist architecture, proven thermal efficiency and lower-carbon material specification in a single engineered solution for high-performance commercial projects.
