Open up your home and entertain in a different way with the Origin Bi-folding window…

This means you can have the same slim sightlines, large openings, functionality, configuration options and opportunity to make your window bespoke to your needs, as you would with the industry-renowned Origin Bi-fold Door.

Made for your needs…

Bi-fold windows fold back on themselves and create a totally uninterrupted view once opened. With such slim sightlines, even when shut, you can still enjoy a spectacular view.

Created completely bespoke to your needs, each individual sash can be made between 400mm and 1200mm wide, opening inward or outward, and folding to left or right. The configuration can be split down the middle or all folding in one direction – however works best for you and your space. The look and functionality of your bi-fold window can be completely customised to your needs, right down to the handles.

Styles tailored to your home…

To add an element of classic yet contemporary elegance, you also have the option of adding Georgian bars to your window design. Often referred to as a steel look, it’s a design that is right on trend that you can have placed however you prefer – horizontally, vertically, or both.

Safety for all the family…

Our bi-fold windows feature special finger-safe gaskets, which protect little fingers from getting trapped, and a magnetic catch to hold the windows in place once open.

Smooth to use…

The track and slimline carriage are the secret to how the Origin Bi-fold Window moves so smoothly – it’s quality in every movement, as they work together to allow the window to move quietly and efficiently.

Handled just right…

Elegant and modern handle styles are available, as the ultimate finishing touch. Offering the ultimate level of design, functionality and strength, our handles are available in stainless steel, or can be colour contrasted or coded for a complete chic finish.
