UPVC CASEMENT WINDOWS have frames made of UPVC, a rigid, and durable plastic material. UPVC is resistant to corrosion, rot, and moisture making it an ideal choice for window frames. These windows feature SINGLE OR MULTIPLE SASHES that are hinged on one side and swing outward to open, the hinged design allows for a full and unobstructed opening, providing EXCELLENT VENTILATION and an unobstructed view when the window is open. Modern UPVC casement windows often come with energy-efficient features, such as DOUBLE – -GLAZED or LOW E- E-GLASS and THERMAL BREAKS. These features help improve insulation, REDUCE HEAT TRANSFER, and lower energy consumption for heating and cooling.
