Fixed skylights are very similar to ventilating skylights overall. The biggest difference is simply that they don’t provide ventilation. If you don’t necessarily need ventilation in the room where you want to add some lighting, then looking into a fixed skylight would be smart. There are those who prefer the fixed skylight option simply because these are perfect for installing in hard to reach areas.
If the ceilings in your home are quite high, then you could easily have one of these installed to provide some dramatic lighting. Being able to enjoy looking up at the night sky is going to feel really nice if you get one of these installed. They work well even on cathedral ceilings, so you will certainly be able to make use of a fixed skylight. The view will look great and the amount of light it will bring into the room is significant.
