New Windows With A Thermal Core At The Heart

Warmcore, The Warmer Choice

WarmCore offers market-leading thermal performance. Traditional aluminium windows can force 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 windows in its class. With exceptional thermal performance, new Warmcore windows help stop heat escaping, lower your heating bills while also retaining the sleek and architectural look of aluminium.

Fresh, Clean Design

With clean, modern lines, WarmCore creates windows with a refined and understated beauty. Perfectly suited to modern architecture as well as replacement projects, from large fixed pane ‘picture windows’ to windows with multiple openers, WarmCore has it covered.

Colour Options

Available, as standard in a choice of 2 powder coated colours with other colours available to order, WarmCore also allows you to pick a different colour for each side of your window. Want a colour outside with white inside? – no problem.

Style Options

A choice of 2 external sash and outer frame designs enable you to personalise WarmCore windows to suit the style of your home.

10 Year Guarantee

All fixings used are chosen to resist corrosion. WarmCore windows carry a 10-year guarantee – covering material, profile integrity and surface finish.

Bi-Fold & Patio Doors

The WarmCore system is also available as wide-span folding sliding doors, as well as single or French doors, ideal for keeping a consistent look with WarmCore aluminium windows. Built to the same exacting standards as the windows, this range brings all the benefits of Warm Aluminium to the doors in your home. Folding sliding doors are available in inward or outward opening configurations up to 6m wide, with as many as 7 opening sashes gliding along custom designed tracks.
