Bi-Folding Doors

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 efficent than traditional aluminium systems.

Built with a revolutionary thermal core at its heart 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 you home.

Warmer By Design

WarmCore has been designed from the ground up to offer market-leading thermal performance, and comfortably meets the requirements of Building Regulations - Part L. Traditional aluminium doors struggle to meet current legislation, forcing you to choose aluminium aesthetics and finish over thermal performance. WarmCore gives you both, with its innovative full width thermal core.

This unique composite construction creates the most thermally efficient folding sliding door in its class. This design philosophy has produced a folding sliding door that has exceptional thermal performance, helping keep fuel bills lower and heat in your home, while retaining the sleek and architectural look of aluminium.
