Solatube® Daylighting Systems feature unique telescoping tubes that can be easily installed even when access to the attic or plenum is limited or there is no space between the ceiling and roof at all. We can also install most products in an open ceiling application where no ceiling exists and the underside of the roof deck is exposed.
One exception to this is the Solatube Smart LED™ System, which requires a minimum height of 16 in. (406 mm) between the base of the ceiling and the roof line. With the Solatube SolaMaster® Series 330 DS-C and 750 DS-C units, the transition box requires approximately a 12 in. (305 mm) depth between the ceiling and the roof.
We recommend you consult your local Solatube daylighting expert for specific details.
