GT Glazing's UPVC doors are manufactured using the market-leading British Profile 22 PVC-U System extruded in the Midlands. Our external UPVC Doors are reinforced with a unique high strength Recycled Composite Material wherever possible, as opposed to carbon inefficient steel or aluminum reinforcing members.
All GT Glazing doors are virtually maintenance-free, with insulation figures up to six times better than timber frames. Not that advanced PVC−U is only a substitute for timber. If you have aging PVC−U or aluminum products, then you'll enjoy similar improvements and cost savings by upgrading your UPVC doors.

GT uPVC doors have been expertly designed to keep out unwanted noises and draughts, so your home stays warm and quiet.
