Dome skylights offer many advantages to the homeowner. They are lightweight and require little to no maintenance. They are the best choice for a skylight if you live in a climate with extreme temperatures, as they keep energy transfer to a minimum. They can be purchased as a single, double, or triple dome, but if it’s energy efficiency you’re after, consider only a double or triple dome.

A dome skylight is suitable for any roof, including flat roofs. In fact, they are particularly suitable for flat roofs due to the fact that they shed water quickly due to the “self-cleaning” aspect of the dome. Typically, the height of the dome is approximately 25% of the width of the skylight, allowing water to quickly flow across the surface.

The ability to collect light from many angles is another big advantage of the dome skylight, as opposed to a flat skylight that only allows direct light in. If the main concern is lighting a room, then a clear acrylic dome is the best option. If you are looking for a softer lighting effect, a white or bronze acrylic dome is the best alternative, especially for those sensitive to light. The white or bronze skylight has the effect of softening the light entering the room and tends to eliminate glare.

Finally, a big advantage of an acrylic dome skylight is that its shape is much stronger than a flat acrylic skylight. Flat plastic sheets typically have a much greater tendency to expand and contract, which can lead to earlier material failure.

In general, the choice of a dome skylight will be determined by your individual needs, but in general, it will be one of the best options if you are looking for a skylight with energy efficiency, lighting capacity and longevity.
