Truly warm aluminium windows

WarmCore is 25% more thermally efficient thanks to a unique, full-width thermal core

WarmCore Windows

WarmCore has redefined expectations of aluminium window and door systems with customers no longer having to choose between aluminium aesthetics and impressive thermal performance.

WarmCore windows are available in both anthracite grey and crisp white for a contemporary look. With casement, tilt & turn and flush window styles as part of the range, thermal performance comes as standard.


Built around a belief that beauty doesn’t have to compromise performance, WarmCore aluminium windows were created out of a desire to combine the desirability and durability of aluminium with unparalleled features...



It's all in the thermal core

At the heart of WarmCore products is a thermal core which significantly out-performs the polyamide thermal breaks commonly used in other aluminium systems. The fully concealed, bright orange, multi-chambered core maximises the use of lower conductivity material to improve thermal performance by up to 25%.
