Thermalight Flat Fixed Glass Rooflights |
.jpg) |
The Thermalight concept is based on an innovative design that delivers maximum daylight due to no internally visible framework. This low profile, high performance system is not prone to the 'water ponding' effect that rival glass products are prone to, due to it's intelligent use of flush external metalwork.
Thermalight rooflights are suitable for both flat and pitched applications, they are available in many shapes and sizes and even come in a walk on variant.
The Thermalight rooflight system is supplied with a complete fixing kit which includes concise fitting instructions for installation by construction tradesmen or DIY enthusiasts.
Single flat fixed Thermalights have a limit of 6 square meters or a length of 4 meters, anything above these limits should be treated as a Multi Pane Thermalight.
