Abstract
A tubular skylight is supported in a building between the ceiling and the roof of the building by a support ring that is connected to the ceiling joists or to the ceiling dry wall. Specifically, a tube ring is engaged with the tube of the skylight to in turn engage the support ring and thereby support the tube. Also, the skylight includes a cover seal that establishes a seal between the roof dome of the skylight and the tube, and that also spaces the flashing of the skylight from the tube to prevent galvanic corrosion and to inhibit heat transfer between the flashing and the tube. The tube includes an upper segment that receives a lower segment, and an expansion seal is positioned between the segments such that the segments can move relative to each other to absorb thermal stresses, with the expansion seal maintaining a seal between the segments.
