What is an acrylic dome skylight?

An acrylic dome skylight is a rounded, bubble-shaped unit made from acrylic plastic and set into a roof opening. It is most often found on flat or low-slope roofs, where a traditional pitched skylight would not sit correctly. The dome sits above the roof surface and lets daylight into the room, hallway, or commercial space below.

These skylights come in two common versions. A single dome has one layer of acrylic. A double dome has two layers with an air gap between them, which slows heat transfer and reduces condensation on the inside of the glazing. Single domes are simpler and less expensive to make, while double domes are more typical where heat gain or winter condensation is a concern.

Acrylic is used because it is light, resists impact better than standard glass, and can be formed into a curved dome. Those traits make it practical for flat-roof buildings, where added weight and fragile glazing can be harder to manage. Acrylic can yellow or cloud over years of sun exposure, so the condition of the dome is a common reason these units are inspected or replaced.

For property owners, the dome matters because it affects daylight, energy use, and roof leaks. The curb and flashing around the dome are the usual points of failure, not the plastic itself. Licensed skylight contractors in Citrus County and nearby areas handle inspection, repair, and replacement of these units. You can find them in the skylight replacement providers listings.
