Rigid Sun Tubes (RST)
Source of natural lighting where regular skylights can’t be installed. Quick, simple installation for any shingle or shake roof. Ideal for interior rooms, closets and bathrooms. Available in sloped and flat roof models. Elbows and tube extensions are available. Columbia Sun Tubes are available in three different sizes. Columbia’s Rigid Sun Tube skylight provides a tunnel that is highly reflective and maximizes the illumination in your room below. As rays of light bounce or bend, their intensity diminishes. The Columbia system is designed to access as much direct sunlight with as few bends as possible.
