A Thermally Broken Rooflight System
The Invisio thermally broken rooflight system is the latest advance in modern roof glazing. Highly insulated glass units can be installed with a frameless appearance using our unique thermally broken rooflight section and silicone jointed panes. Thanks to the advanced design of our thermal break technology these frameless rooflights can be made to very large sizes, allowing lots of light to enter spaces below.
Sightline: frameless finish
Thermal Insulation: Uw values from 1.2 W/m2K
Snow Loading: up to 2.02 kN/m2
Max. Size: recommended max size 1.5m x 3m per unit
Pitch: 0 to 45 degrees
Glass Specification: up to 37.5mm thick double glazed unit with toughened laminated inner pane for safety
Shapes: square or rectangular as standard, other shapes available on request.

The unique thermally broken design of this rooflight system eliminates the normal cold bridging issue you get with normal flat rooflights. With a thermal break within the aluminium profile the internal and external faces of metal are completely thermally separated. This provides a much better thermal performance as well as better environments for the built space (reduces energy loss and no condensation/frost on the frames).
There are two external design options with this rooflight system; first of all, you can choose the glass to end flush with the frame, alternatively you could choose for the glass to be stepped over the edge of the frame. Both options are possible. The panes can also be silicone jointed, in keeping with a frameless finish.
We have this rooflight system available to see at our showroom in both built structures and hand-held samples to see the integral technology. Contact us for quotes or showroom appointments.
