Opening Roof Window – Dual Action

Opening Roof Window – Dual Action


Transform your attic or loft

Roof Windows let you transform attic spaces into beautiful living areas filled with Daylight and Fresh Air. The Vent Flap adds the extra convenience of controllable passive ventilation – even when it’s raining! The Pivoting Roof Windows are made of treated pinewood and pre-coated with clear acrylic lacquer. From the outside, they are protected by maintenance-free aluminium cappings.


In addition to opening, the Roof Windows have the added benefit of a Vent Flap. The Vent Flap allows you to have passive ventilation in your home all day long and can be left open while the roof window is closed.

Easy to use

VELUX Roof Windows are purpose-built for manual, in-reach operation, this makes them perfectly suited for a converted attic or loft. Opening for ventilation is a breeze, a simple pull of the top control bar opens the window completely in a matter of seconds.
