uPVC Windows & Doors System
Why use uPVC?
uPVC (unplasticized polyvinyl chloride) is a rigid, non-plasticized form of PVC engineered specifically for window and door frames — a different formulation from the flexible PVC used in pipes. It doesn’t rot, corrode, or warp, has no organic material for termites or moisture to attack, and its multi-chamber profile traps air inside the frame to cut heat transfer — a real factor in Karachi’s humidity, Lahore’s temperature swings, and monsoon-driven rain. On wider openings, the frame needs a galvanized steel core to resist wind load and its own weight; without it, “uPVC” from one supplier can differ by 40% in price and lifespan from another’s. WinGlass fabricates every frame to this standard — fusion-welded corners, multi-point locking, EPDM gasket seals, and steel reinforcement where the span demands it — drawing on 40+ years of combined experience in windows, doors, and glass.
