Alexander Windows has over 26,000 square feet of manufacturing space to fabricate our uPVC window and door frames. We don’t buy our frames; there is no middle man and we have full control over everything from start to finish.
All windows and doors are made on-site using the Kömmerling Connoisseur 70mm section. Windows have multi-point reverse action in-line locking, with key lockable handles and a night vent position. Doors have a minimum of 6 point locking, with kitemarked anti-pick and drill cylinders to British Standards. All of the upvc frames we manufacture are internally glazed for maximum security as standard.
