The Solatube® International, Inc. roof components have been designed for installation at the roof level, not on a vertical wall. By installing the roof components on a vertical wall, the product warranty would be voided. However, installations of this type have been done successfully. We recommend a warranty from the installer to cover this type of application.
An application where the roof components are mounted on the roof and the tubing makes a 90 degree turn to allow the diffuser or Decorative Fixture to be mounted on an interior wall are within the bounds of the warranty.
For more information, please contact your local Solatube daylighting expert.
