Warmcore, the warmer choice that saves you money
The traditional weakness of aluminium doors has been the aluminium itself. While a beautifully strong and hard-wearing material, aluminium is a good conductor of energy. Meaning that the warmth from your home finds an easy path outside, leaving you colder and with higher heating bills. Most aluminium folding sliding doors try to overcome this inherent weakness by replacing a section of aluminium with a small thermal break of less conductive material to lessen this heat loss.
WarmCore took a different approach, from inception this revolutionary folding sliding door was designed to be as thermally efficient as possible. Built around a full-width thermal core - maximising the use of low conductive material - WarmCore is 25% more efficient at keeping heat in your home than traditional aluminium doors. Yet it doesn’t compromise strength as the outer faces of the profile are high-grade aluminium, positioned to add the greatest structural rigidity.
