Solar skylights are also called sun tunnels, light tubes, and tubular skylights, but they are all structurally similar. an acrylic or poly-carbonate dome installed on the home’s roof catches the sunlight, which is reflected down a rigid or flexible sheet metal tube in the attic before shining on the diffusing lens in the room’s ceiling. they can be 10-inch, 14-inch, or larger. both skylights and solar tubes shine light from above the home into the interior. therefore, they can only be used on the building’s highest floor.
Installing a solar skylight is easier than it sounds, given that it is done by a professional. the whole job can take as little as two hours but certainly no more than a half day. The solar skylight/dome is installed on the roof with the proper flashing, and the tube is extended from the dome to the room’s ceiling. The diffuse is then set into the ceiling without needing to do more than minimal interior finishing work.
