Origin Aluminium Casement Windows

Origin Casement Windows can be fully customised to your requirements, with left-, right-, or top-openers, as side-hung, top-hung, or fixed dummy sashes. Every window is bespoke, so we combine different opening types and fixed frames into one seamless unit to suit your home’s ventilation and architectural needs.

The aluminium profile offers exceptional thermal efficiency, with U-values of up to 1.2W/m²K. Our casement windows also offer some of the slimmest sightlines on the market, like the OW-70’s 65mm profile. Even with the windows closed, you get maximum light penetration and the best view of the outside world, improving your home’s energy performance.

The OW-80 Casement Window features an industry-first flush casement on both the inside and the outside, for a sleek, modern finish. The seamless design can be manufactured in any bespoke configuration, so it’s a stunning addition to any modern home.

Our casement windows can accommodate large maximum sizes; for example, the OW-80 side-hung casement can be up to 1,800mm high and 1,000mm wide. Windows can also be coupled together, so we have a complete window solution for any size aperture or complex overall configuration your project may require.

Choose from a range of modern handle styles, available in premium metallic finishes or Origin’s colour-coded options to match the window frame. The handles, like the OW-70’s Hardex Electro finish, are smooth and of the highest quality, so that you can choose the perfect finishing touch.

For a touch of classic yet modern style, you can add Georgian bars to your window design. This popular style, often referred to as a steel look, can be customised with bars running horizontally, vertically, or both so that you can tailor the window to your traditional or industrial look.
