The traditional weakness of aluminium windows 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 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 completely 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 aluminiumm, positioned to add the greatest structural rigidity.
WarmCore double glazed windows have a Uvalue of U1.3 and triple glazed they are at a value of U0.8. These beautiful, strong and secure windows are 25% more thermally efficient than the competion. In addition a full 10 year warranty is provided.
