At Cambridge Skylights, we often get asked about the difference between a 'roof light', a 'skylight' and a 'roof window'. The truth is that there is little difference between these terms, but nuances do exist due to the industry's continuous evolution. In this blog post, we aim to clarify these definitions and end the confusion once and for all.
What is a roof window? How does it differ from a rooflight or skylight?
Roof windows are outward-opening windows integrated into a roof's design, usually with standard sizes and specifications. Velux is one of the most recognizable brands of roof windows. In contrast, rooflights/skylights are products installed in flat roofs or pitched roofs that stand out from the roof line more than roof windows do. They are typically installed on an upstand or kerb system that ensures water runoff, and they can be installed within listed buildings where new window openings are not permitted.
