Triple Glazed Structural Glass
Bespoke Flushglaze Eaves Windows
IQ Glass designs and manufactures bespoke flushglaze eaves windows that create a seamless connection between vertical glazing and roof glazing. Using specialist structural glass engineering, these frameless glazing systems maximise natural daylight while maintaining a clean architectural appearance.Ideal for contemporary homes, extensions and commercial buildings, flushglaze eaves windows can be designed in a variety of sizes and configurations to suit the requirements of each project. Available with high-performance double or triple glazing, they provide excellent thermal insulation whilst delivering uninterrupted views and minimal visible structure.
The CAD Details for the Invisio System are available to request here.
Structural Glass Supports
Every flushglaze eaves window is individually engineered according to its size, structural loading requirements and roof configuration. Depending on the span and glazing specification, additional support elements may be incorporated while maintaining a minimal visual appearance.
If the glass slope is directed back towards the connected building a specialised structural gutter can be utilised to drain water away, connect the Eaves Window to the building and support the building edge of this structural glass rooflight.
The structural glass assembly can be made from multiple glass panels for extremely long Eaves Windows. If the Eaves Window width is below 1.3m then no visible supports will be needed to the horizontal roof panel. If over 1.5m IQ Glass can design slim steel supports of near invisible glass beams to support the structural glass assembly.

Strengthening Interlayers for Eaves Windows
Specialist strengthening interlayers allow the vertical glazing element to support the roof glazing above, reducing the need for visible steelwork and helping to maintain a frameless flushglaze appearance.
Using specialised strengthening interlayers within the vertical glass these clear panels of glass can effectively carry the load of the above glass unit, creating a glass boxed rooflight with no visible supports of frame.
Weather Sealing & Drainage For Flushglaze Eaves Windows
Where the glass units meet at the horizontal connection the only sightline on view will be the spacer bars of the highly insulated glass units and a slim structural silicone seal, effectively weather sealing and adhering this glass to glass connection.
The flushglaze detailing creates an elegant glass-to-glass connection while providing reliable weather protection and long-term durability.
Effective drainage design is critical to the long-term performance of any flushglaze roof glazing installation. Each eaves window is engineered to manage rainwater efficiently while preserving the clean aesthetic of the glazing system.
Depending on the slope of the horizontal element of the Eaves Window IQ Glass can design a small and discrete drip off ledge to the glass, draining water away from the surface of the vertical panel to reduce water marks and pooling.
Benefits of Flushglaze Eaves Windows
Enhanced Natural Light
The glazed junction between wall and roof allows additional daylight to enter the building compared to conventional window designs.
Minimalist Architectural Design
Flushglaze detailing creates clean lines and a frameless appearance that complements modern architectural design.
Bespoke Structural Glazing
Each eaves window is designed specifically for the project, allowing for a wide range of angles, dimensions and glazing specifications.
High Thermal Performance
Double and triple glazed units can be specified to achieve excellent energy efficiency without compromising aesthetics.
Specification
Specification Information
The structural glazing used to create eaves windows have a maximum size of 6m x 3m per glass pane. Depending on the size of the glazing and the weight, glass beams or steel sections may be necessary to provide structural support to the glass to glass connection. Glass beams or steel sections are required if the glazing is over 1.3m wide in size.
The construction and fixings used for eaves windows are all different and specific to each project. Contact IQ Glass for more information.
Triple Glazed Structural Glass
Eaves windows can be constructed with triple glazing for enhanced thermal and acoustic performance. IQ Glass uses the Invisio+ structural glazing system, whose deeper profiles allow for high-performance triple glazed units while maintaining a minimal, frameless appearance.
