Thermal efficiency

Thermlock Technology

Prestige casement windows combine the clean lines of aluminium with exceptional thermal performance. An innovative Thermlock multi-chamber thermal design is hidden within the aluminium frames, helping to insulate against any kind of weather.

The closed-cell insulating chamber acts as a thermal break and works in conjunction with high-performance glazing to create leading thermal performance, far superior to traditional polyamide thermal breaks. The window’s cills also feature this technology, coupled with built-in weather sealing to protect against draughts and rain.
