Continental Folding Doors Overview

Continental Folding Doors

Continental Folding Doors

Unlike ordinary sliding patio doors, bi-folding doors give over a 90% clear opening. The opening creates extra room for entertaining and lets the outside in. We are able to produce these folding sliding doors in many different configurations in order to make the panels slide and fold away to an unused part of your garden or room. We can manufacture doors with between two and seven panels as standard.

This door system can achieve wide and tall doors panels, this results in less panels in wider doors and therefore more glass, more light and less frame.
