GLOW HEATED GLASS by TuffX – heated glass for bi-fold doors
Using advanced infrared heating and complete thermostat control, Glow transforms aluminium bi-fold door units and roof infill panels into powerful, invisible heat sources.
This game-changing innovation from TuffX is not just heated glass – it’s heating, in the glass. Installed just like standard bi-fold doors and fully compliant with EN 12150 and EN 1279, Glow delivers 35–40°C radiant warmth with U-values as low as 0.7 W/m²K, offering a high-performance, plug-in alternative to traditional radiators for extensions, garden rooms and conservatories.
Glow provides primary heating at around 9p per hour per bi-fold panel, while reducing condensation, keeping sightlines clear and freeing customers from bulky wall-hung heat emitters. Glow also reduces condensation, inhibits mould growth and maintains clear views. Plus, with no routine maintenance and only a simple electrician connection to 240v, Glow elevates functional glass and unlocks new layout possibilities, all while looking identical to standard bi-fold doors and glazing.
