Launching Invisio+: Frameless Structural Glass for Triple Glazing in Private Homes

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 private residential projects.

Developed for luxury private residences, coastal villas, private estates and contemporary new-build homes, Invisio+ allows large-format frameless glass to be specified with improved thermal performance, refined detailing and fully concealed structural support.

Understanding Invisio+ for Luxury Residential Design

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.

For private homes, this opens up new opportunities for expansive frameless glass in demanding residential environments, from coastal villas and tropical residences to cold-climate homes where comfort, thermal performance and clean architectural detailing must work together.

Structural glass has become one of the defining features of contemporary residential architecture, creating transparent facades, hurricane-resistant windows, frameless glass walls, eaves glazing and glass links between spaces. By eliminating visible framing, it allows homes to be defined by light, proportion, landscape and uninterrupted views.

Concealed Fixing for Frameless Glass

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 important for private homes where glazing must respond to local climate conditions, building performance expectations and project-specific glass requirements. Whether the home is located in a coastal, tropical or colder climate, Invisio+ provides a tested structural glazing system that can be considered as part of a wider high-performance facade strategy.

Exclusively available through IQ Glass and specified through IQ Glass International for homes across the US, Caribbean and beyond, Invisio+ supports architects, designers and homeowners seeking large-format frameless glazing with verified performance, low-carbon material specification and fully concealed structural detailing.

Thermal Performance for Large-Format Residential Glazing

Exceptional design demands equally exceptional performance. Invisio+ has been engineered and extensively tested at architectural scale, providing architects and specifiers with performance data that reflects the demands of large-format frameless glass in private homes.

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 triple-glazed unit with a glass unit U-factor of 0.12 Btu/h·ft²·°F, Invisio+ achieves an approximate system U-factor of 0.10 Btu/h·ft²·°F. The system was tested on an assembly measuring approximately 10ft by 20ft, reflecting the scale of contemporary residential glazing where large glass elevations are increasingly used to create open, light-filled living spaces.

The system is capable of supporting structural glass panels up to approximately 20ft in height with no internal mullions, enabling uninterrupted glazing with the clean, minimalist detailing expected from high-end frameless glass design. With the fixing system concealed within the surrounding building fabric, the facade 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. A key feature of the system is full glass removability, allowing individual glass panels to be replaced independently of the primary fixing system. For private homes, this offers a valuable long-term maintenance benefit by reducing disruption if a panel ever needs to be replaced in the future.

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

Where Invisio+ Can Be Used in Private Homes

From coastal villas and super-prime residences to contemporary new-build homes and major residential renovations, 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 high thermal performance, Invisio+ enables architects and homeowners to achieve ambitious glazing designs without compromising performance, comfort or buildability.

The system is suitable for a wide range of private residential applications, including:

• Super-prime residential homes and private villas

• Coastal and tropical residences

• Contemporary new-build homes

• Major residential renovations and extensions

• Private estates and second homes

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 contemporary residential architecture.

Lower-Carbon Structural Glass for High-Performance Homes

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 thermal performance, Invisio+ supports residential projects seeking to reduce both operational energy demand and embodied carbon. The system is also compatible with low-carbon glass substrates, offering architects and design teams greater flexibility when creating homes that respond to increasingly ambitious sustainability targets 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 residential architecture, proven thermal efficiency and lower-carbon material specification in a single engineered solution.
