The Traditional weakness of aluminium windows and doors has been the aluminium itself. While a beautifully strong and heard 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 systems 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 window and door system was designed to be as thermally efficient as possible. Built around a full width thermal core - maximising the use of lower conductivity material - WarmCore is 25%* more efficient at keeping heat in your home than traditional aluminium solutions. Yet it doesn’t compromise strength as the outer faces of the profile are high grade aluminium, positioned to add the greatest structural rigidity.
Robustly designed to take the weight of triple glazed units as standard, choose this option for the ultimate thermal performance at 75% better than standard double glazed aluminium windows. Opting for 44mm triple glazing rather than standard 28mm double glazing reduces the whole window U-Value rating from 1.3 to 0.8. Triple glazing is ideal for WarmCore windows installed in exposed locations
