WarmCore Windows

Fresh, Clean Design - the perfect window

Built around a belief that beauty doesn’t have to compromise performance, WarmCore aluminium windows were created out of a desire to combine the desirability and durability of aluminium with unparalleled insulation. The unique, full width thermal core is key to why WarmCore windows are 25% more thermally efficient than traditional aluminium systems.

Strong and secure, WarmCore windows come with multi-point locking, internal beading and are backed by a 10 year product guarantee - helping keep you and your home safe. Available as casement or tilt and turn windows, and with a flush sash option that brings the outer frame perfectly level with the opening part of the window - WarmCore windows are the perfect warm, secure and beautiful addition for your home.

Technical Information

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. Attention has even been paid to how the window sashes look when open, with the black full-width thermal core creating a neat and thought-through appearance.

Beautiful, strong and secure
windows that ARE 25% more thermally
efficient than the competition

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 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.
