What is the difference between skylights, rooflights and roof windows?

Frequently mistaken for the same product, skylights, rooflights and roof windows are not, in fact, the same. 

A rooflight and skylight are the same roofing product though, just alternative ways to refer to an opening in a roof that’s covered with translucent or transparent material to let in natural lighting. Whereas a roof window is completely different as it can be opened or closed to regulate ventilation in the room, this product is most popular for residential attic spaces. Find out which product will be most suited to your building refurbishment below.

Roof window 

A roof window must be installed in the same orientation with the surrounding roof, to give a subtle and blended in appearance. They have a similar look to skylights and rooflights as they both have a glazed glass unit that lets in natural lighting into a residential or commercial building. Although a roof window differs as it can be opened or closed when desired, to regulate air flow and ventilation. A roof window is typically smaller than a roof light, so if you’re looking for an addition that increases the natural lighting and airflow in your building, a roof window is perfectly suited to your needs!
