We have been manufacturing uPVC windows and doors for over 20 years now, and have built up a wealth of both knowledge and experience. Our fabricators are time-served, and any apprecntices are trained to the highest possible standard by some of the best in the industry.
Alexander Windows has over 26,000 square feet of manufacturing space to fabricate our uPVC window and door frames, which are made to order for both our Supply Only Division and our Domestic Division. 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 five-chamber, Kömmerling Connoisseur 70mm section. Windows all have multi-point reverse action in-line locking systems, with key lockable handles and a night vent position as standard. Doors have a minimum of 6 point locking, with kitemarked anti-pick and anti-drill cylinders to British Standards. All of the upvc frames we manufacture are internally glazed and fully steel reinforced for maximum security as standard.
