Bi-Fold doors are the perfect partner to maximising the light intake and access to any exterior facing room, particularly a garden/patio facing room. In contrary to sliding doors a bi-fold door can remove almost all evidence of the door, and make it as if the room is part of the garden/patio. At Prime Aspect Windows we make sure our understanding of the benefits of each type of door is clear so our customers can make informed decisions and get the most out of their home. We have the widest range of bi-fold doors in the North East and Darlington. We carry out Bi-Fold new installations, repairs and maintenance.
