What’s the difference between the two? Skylights install flush to the ceiling. No wood is visible. They are stationary, which means they don’t open for ventilation. Only Andersen® skylights feature a snap-in sash that makes installation much faster and easier.
Roof windows, like the windows in your walls, are set back from the interior surface with jambs. Ours are made of clear pine, which adds the beauty of natural wood -- as well as natural light -- to your home. Roof windows can be either venting or stationary.
