Abstract
A tube assembly of a tubular skylight is formed with upper and lower notches for respectively snappingly engaging tabs of upper and lower support rings to promote ease of installation. The upper support ring has a flange that overlaps the edge of a roof-mounted flashing such that the upper support ring rests on the flashing with the tube assembly suspended from the upper support ring. A transparent cover covers the tube assembly, and an upper seal is sandwiched between the top edge of the flashing, the cover, and the upper support ring to keep moisture and dust from entering the upper end of the skylight. Screws secure the flashing to the upper support ring, with spacers being disposed around the shanks of the screws between the heads of the screws and the flashing such that thermal expansion can be absorbed. On the lower end of the tube assembly, a dress ring supports a light diffuser, and the dress ring includes spring clips that snappingly engage receptacles on the lower support ring. Thus, the principal components are snapped together to assemble the skylight. A hollow lower seal is sandwiched between the tube assembly, diffuser plate, and dress ring such that only a single seal is required to seal the lower end of the skylight from moisture and dust.
