Warm Core

Strong and secure windows that are 25% more thermally
efficient than the rest.

The unique, full width thermal core is key to why WarmCore windows are 25% more thermally efficient than traditional aluminium systems.
They come with a multi-point locking system, internal beading and corrosion resistant fixings.

They are available as casement windows, tilt and turn windows, and there is also 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.

With clean, modern lines, WarmCore creates windows with a refined and understated beauty. 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.
