Bi folding doors are a great way of bring the outdoors into the room. They open up any room and have far more  versitility of patio sliding or French doors. Bi folding doors come in a range of designs and are produced in uPVC and aluminuim - both of which come in a large colour range. Here at Polar Bear Windows we offer the supply and installation of uPVC and aluminuim bi fold doors- all made to measure and fitted by our highly trained and experienced craftsmen.
