Built with a revolutionary thermal core at its heart…

Strong and secure, WarmCore windows come with multi-point locking and internal beading – helping to keep homes 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.

Whether you are tucked up inside watching TV with your WarmCore windows protecting you from the elements, or have your windows flung wide open on a hot summer’s day you can be assured your high performance aluminium windows will look pristine.

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. 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.

Tilt & Turn

For the ultimate in versatility the WarmCore system is available as a tilt and turn window.

Ideal for use in upstairs locations, tilt and turn windows can be tilted inwards for ventilation – helping keep your home aired and fresh, alternatively they can be swung inwards for cleaning, or for when the day is too glorious to be locked out.

Using the latest multi-point locking, and custom-designed hinges, tilt and turn windows are as safe and secure as the rest of the WarmCore range.

Flush sash – clean and contemporary styling

WarmCore casement windows are available in a ‘flush sash’ option for the ultimate in clean, modern aesthetics. Using a stepped outer-frame, the sash – the opening part of the window – sits on the same plane as the rest of the window, creating a pure, cutting-edge look to this high performance window system. In addition where two flush sashes meet, WarmCore uses a feature mullion – which echoes the flush sash feature, creating a precise bead line in-between the two windows.

Colour options

Available, as standard in a choice of two powder coated colours with other colours available to order, WarmCore also allows you to pick a different colour for each side of your window. Want a colour outside with white inside to leave you free to change your interior in the future? – with WarmCore that’s no problem.

Style options

A choice of two external sash and outer frame designs enable you to personalise WarmCore windows to suit the style of your home. The pencil round styling helps to give a softer aesthetic, while the square styling creates a precise contemporary look.
