Benefits of roof access windows

Fresh air and a better indoor comfort

Sleeping, showering and cooking all increase the overall humidity levels in our homes. Poor indoor air quality seriously affects our general well being, but a few daily routines can have a great effect on your indoor comfort. Let VELUX roof windows give you a helping hand. Simply use the pre-defined ventilation programs and enjoy automatic airing.

No chance for leaks

All VELUX skylights and roof windows come with our "No Leak" promise, which means with proper installation, you can live worry-free when it comes to leaks inside your home.  Please see the warranty page for full details.
