Warmcore Windows & Bi-Folding Doors

This new window and door system is designed to be as thermally efficient as possible, built around an innovative full width thermal core, with an aluminium outer frame, keeping your heat in your home yet not compromising on strength as the outer profile is made from high grade aluminium.


Strong and secure, Warmcore windows and doors are 25% more thermally efficient than traditional aluminium systems and come with multi-point locking, internal beading and a 10-year guarantee.

Available with a flush sash option that brings the frame perfectly level with the opening part of the window or door.


Warmcore aluminium was created to combine desirability and durability out of aluminium with insulation, the bi-folding doors come with ERA five star security built in.

Inwards or outwards opening doors up to 6m wide, with as many as 7 opening sashes that glide along custom tracks.

A range of colours and configuration options help you choose the perfect door for your home.
