Introducing Multifold Doors Casement Window

Windows bespoke to your exact requirements and delivered with all the benefits of style and security.

The Multifold Doors Casement Window by Origin

Casement windows are an excellent way of allowing natural light into your Buckinghamshire and Home Counties home and creating a sense of space. Origin Casement Windows are available in either our OW-70 or OW-80 ranges.

Our OW-70 offers the thinner sightline, which facilitates more glass and better views. However, the OW-80 can be manufactured in a larger size, up to 7.0 square metres.
