Tradesmith Ltd are now manufacturers of Warmcore Aluminium

Traditional aluminium systems can force you to choose aluminium aesthetics and finish over thermal performance. WarmCore gives you both, with its innovative full width thermal core.

Arguably the defining product of 2016 for the fenestration industry, WarmCore folding sliding, French and residential door system has been adopted by housebuilders and homeowners with equal enthusiasm and our newly introduced WarmCore aluminium window is built around the same full width thermal core concept.
