VELUX WHITE Polyurethane TOP-HUNG Roof Window GPU
The top-hung window is manufactured in high quality pine with the option of a white painted internal finish (GPL) or white polyurethane internal finish (GPU). It is suitable for installation into roof pitches between 15° and 55°. For installations between 55° and 75° special springs will be required.
Not advised for high level (out of reach) installation. The bottom edge of the window should be placed approx. 0.90 – 1.20m above the floor for ease of operation.
- Ventilation bar with dust and insect filter – Allows fresh air to enter the room while the window is securely closed
- Sash rotates 180° from inside – Allows easy and convenient cleaning
- Barrel bolt – Allows the window to be locked in to position at 180° for secure cleaning of the exterior pane internally
