White PVC Double Hung Window Frame 1000x1500mm Vertical Sliding Sash

Description

• Traditional vertical sliding sash design re-engineered with modern PVC profiles, offering the classic aesthetic of a double hung window with the durability and low maintenance of uPVC construction.
• Both upper and lower sashes slide independently within the frame, allowing flexible ventilation control — open the top for warm air extraction or the bottom for cool air intake.
• Tilt-in sash design enables both glass panels to be tilted inward for convenient cleaning of exterior surfaces from inside the room, eliminating the need for external access.
• Built-in spiral balance system provides smooth, controlled sash movement with the ability to hold the window at any position without additional hardware.
• Compatible with double-glazed units up to 24mm; includes integrated weather seals and a concealed drainage system to manage condensation and rainwater effectively.
