Folding Sliding Doors & Aluminium Windows
WarmCore folding sliding doors and windows feature unparalleled insulation, using a hidden orange thermal core in the frames which is 25% more thermally efficient than traditional aluminium systems. Strong and secure, WarmCore doors and windows come with class leading security built in, backed by a comprehensive 10 year product guarantee.
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.
Choice of Styles
Whatever the style of your home, WarmCore folding sliding doors have the options that enable you to create the door that matches your needs.
Available in a choice of 4 hard-wearing powder coated finishes, WarmCore’s unique composite construction enables you to choose a different colour for the interior of your door from the outside, at no extra cost.
There is also a choice of 4 external aluminium designs for the door sashes, 4 threshold options and a choice of 3 handle finishes, Matt Black, Brushed Graphite and Satin Silver.
