Fixed skylight
A fixed skylight is a roof-mounted window unit that is sealed shut and admits natural light only, with no ability to open for airflow. It is the simplest and most common skylight type for rooms that need daylight but not ventilation.
A fixed skylight is a roof-mounted glazing unit that does not open. The glass or acrylic sits in a sealed frame, so the only thing that passes through it is daylight. Because there is no operating hardware, no crank, no motor, and no hinge, a fixed unit has fewer moving parts to wear out or fail.
The main reason homeowners choose a fixed skylight is simple: it brings light into spaces where opening the roof is not needed. Hallways, stairwells, bathrooms with an exhaust fan, and interior rooms with no exterior wall are common examples. In Citrus County, where many homes are single-story ranch or block construction with long roof runs, a fixed unit is often the practical way to add daylight to a center hall or kitchen without making the roof more complicated.
Fixed skylights also tend to be the most airtight option. Venting models need a weatherstripped operable sash, which is one more place where water or air can get in. A fixed unit only needs a good flashing and curb seal to keep water out. That is one reason they are often specified where leaks are a concern.
The term is used to separate fixed units from venting skylights, which can be opened manually or with a remote or motor. When someone asks for a fixed skylight, they are asking for light only. If ventilation or heat release is also a goal, a venting unit is the better fit, and the two are usually compared on that basis.
If you need a fixed skylight installed or replaced, you can find local providers in the skylight installation category.
