Origin OW80 Side-Hung Casement Window

Origin OW80 Side-Hung Casement Window

The Origin OW80 Side-Hung Casement Window is a side-hung casement window, made to measure on the Origin OW-80 thermally broken aluminium system. Slim aluminium sightlines let in more glass and more light, while the polyamide thermal break keeps the warmth in. Every window is cut to your exact size, finished in the colour you choose and delivered ready to fit.

This configuration

A single sash hinged at the side, opening outward, with a choice of left or right hinge. Simple, secure and easy to operate. Ideal for living rooms, bedrooms and general rooms that need everyday ventilation.

Engineered for real British weather

Aluminium does not warp, swell or rot, and the OW-80 profile is built to shrug off wind and rain on exposed elevations. The thermally broken frame with a warm-edge, argon-filled double-glazed unit meets Part L, so rooms stay comfortable and running costs stay down. For coastal homes we can specify a marine-grade finish and corrosion-resistant hardware, guaranteed for salt-air locations.

Your window, your way

• Any RAL colour. Anthracite, jet black, white and the full RAL range, powder coated, with a dual-colour option so inside can differ from outside.
• Glass to suit the room. Standard 28mm energy-efficient double glazing as standard, with acoustic, solar-control, self-cleaning, privacy and triple-glazed options.
• Made to measure. Priced live by the millimetre, so you are never forced into a standard size.

Secure as standard

Security is built into the frame, not bolted on. Rigid aluminium profiles with fabricated corners give the window its strength, and multi-point locking is designed to meet PAS 24 where the configuration allows. Toughened and laminated glass upgrades add a further layer of protection.
