How are the extension tube sections fastened together?

Most Solatube® Daylighting Systems feature tubing with a specially designed notching system that allows one tube to telescope into the next, so they rarely have to be cut to length. High-quality foil tape is used to seal all tubing seams. This keeps bugs and dust from entering the system, ensuring maintenance-free operation. Tube sections are further reinforced by fastening them with provided self-tapping screws for structural integrity.

One exception is the Solatube SkyVault® Series, which features a patented Tab-Lock Connection System that guarantees proper assembly. Additionally, Tube Belts ensure structural integrity by cinching the tube connection to prevent gaps and provide a tapeless, self-sealing joint. This combination of features simplifies installation and reduces labor costs.
