To add a little light to the inside of your shed, a dome skylight is an economical and easy solution. This 22" square skylight installs easily to the roof. Be sure to follow the manufacture’s installation instructions or discuss it with your project advisor. Improper installation may result in leaking around the skylight. Made of a heavy Polycarbonate, this skylight lets in the light, but blocks out the harmful UV rays. It is slightly tinted as well. Polycarbonate skylights are very durable, and will hold up to harsh weather conditions.
