If you’ve been in the skylight game for a while, you’ve likely got the difference between skylights and roof windows down pat. If you haven’t, it might be surprising to hear there are differences at all.
While they both allow daylight and fresh air to flow through the roof of a home, there are a few slight differences between skylights and roof windows. And it’s important to know which to install when to ensure everything is up to code when you’re done.

Difference between Skylights and Roof Windows
The main difference between skylights and roof windows is that skylights are slightly more versatile. Skylights can be mounted to a curb, which offers more installation options. Roof windows, on the other hand, must be installed in the same orientation and plane as the surrounding roof at a minimum 15˚ pitch.
When we get VELUX-specific, roof windows and skylights have a few more nuanced differences. Our skylights, for example, are compatible with a wider range of blinds compared to roof windows. And our roof windows, since they’re all manually operated, are not compatible with VELUX ACTIVE with NETATMO.

Roof Windows provide high intensity, direct light
Roof windows provide that bright daylight we enjoy so much. Actually, not only it is enjoyable, but it turns out it’s so important to our overall health!
“Daylight has been used for centuries as the primary source of light in interiors and has been an implicit part of architecture for as long as buildings have existed. Not only does it replace electric light during daytime, reducing energy use for lighting, it also influences both heating and cooling loads, which makes it an important parameter of an energy efficient design. Additionally, recent research has proved that daylight provides an array of health and comfort benefits that make it essential for buildings’ occupants.” DEIC Book, Velux
