Welcome a world of light into your home with the VELUX Top-Hung White Polyurethane Windows.

With the white polyurethane finish you can give the ultra-modern look within your home. We recommend placing these windows at eye-level and take full advantage of panoramic and unobstructed views.
The VELUX Flashings are required to install roof windows and are suitable for these roofing materials:

  • Tiles up to 120mm in profile (EDW)
  • Plain Tiles 15mm thick (EDP)
  • Slate 8mm thick (EDL)
  • Uncertain on flashings you need – use this guide to help you find out or contact us.

The VELUX Top-Hung White polyurethane (GPU) window suits almost any modern home and living area and will create an ultra-modern, sleek finish in your home.

With a hinge from the top of the window, the top-hung roof window can open outwards to a maximum angle of 45º maximising the panoramic and unobstructed views out of the window. The GPU (white polyurethane) is available in 15 different sizes starting from the CK04, measuring 55cm high x 98cm wide, to the UK08 at 134cm high x 140cm wide.

The top-hung windows feature the ability to rotate 180º allowing for easy cleaning from inside using both hands. The ventilation flap means the room can be ventilated even when the window is closed. The new VELUX ThermoTechnology™ means these roof windows have a low U-Value of 1.3 W/m2K and a high performing energy efficiency.

The white polyurethane top-hung VELUX window, as ever, comes with the VELUX 10-year guarantee and are quick, easy, and safe to install. They are suitable for roof pitches between 15º and 55º. This roof window can also perform as a recognised and approved fire escape.
