Warmcore; The beautiful, strong and secure door that is 25% more thermally efficient than the competition

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.

Precision engineering

From the sturdy quad-wheeled rollers, to the multiple weather-seals, every element of your door is precisely manufactured to exacting standards. Performance, reliability and ease of use comes from a meticulous attention to detail.

Custom high-strength rollers with a 200kg load capacity are at the heart of ensuring the smooth operation of the WarmCore door. Tested to over 50,000 cycles, these precision components ensure years of trouble-free, reliable operation.

From the anodised finish of the hardware – suitable for coastal use – to the 60-80 micron powder coat finish on the aluminium (marine grade is 40 microns thick), WarmCore folding sliding doors have been designed to stand the test of time. All fixings used are stainless steel – chosen to resist corrosion – and tough extruded aluminium hinges, along with the quad-wheeled track rollers are precision engineered to perform consistently every single time, year on year.

In keeping with this attention to quality, WarmCore doors carry a comprehensive 10 year guarantee – covering materials, surface finish and operation.
