Arguably the defining product of 2015 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.
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 insulation. The unique, full width thermal core is key to why WarmCore windows are 25% more thermally efficient than traditional aluminium systems. Strong and secure, WarmCore windows come with multi-point locking, internal beading and are backed by a 10 year product guarantee - helping keep you and your home safe. Available as casement or tilt and turn windows, and with a flush sash option that brings the outer frame perfectly level with the opening part of the window - WarmCore windows are the perfect warm, secure and beautiful addition for your home.
