Dome skylights are useful in many ways to the homeowner. Since they are light weight, they are easy to install, operate and maintain. These types of skylights are best for areas where climate conditions are extreme as they keep energy transfer to a minimum. There are different varieties of these skylights. You can purchase them as a single, double, or triple dome. If you want more energy efficient ones, then you should only consider a double or triple dome. Dome skylights are suitable for any type of roof, including flat roofs. In fact, they are more suited for flat roofs because of the fact that they shed water quickly due to the "self-cleaning" aspect of the dome. Usually, the dome's height is around 25% of the width of the skylight that allows the water to quickly flow off the surface. These skylights also have the ability to gather light from different angles. Unlike flat skylight, they allow in more light. If you want to illuminate a room, then a clear acrylic dome is the best option. If you are looking for a more lighting effect then a white or bronze acrylic dome is the best choice especially for light-sensitive people. Finally, these are very strong kinds of skylight and hence offer better safety.
