Velux commercial SUN TUNNEL™ skylights are the most economical way to bring natural light into your business space, whether it is a commercial office, school, or large warehouse.

The natural daylight from the SUN TUNNEL™ skylight in commercial buildings can improve worker productivity while lessening energy costs through reduced heating, cooling, and electricity expenses.

The TCR model consists of a curb-cap style flashing to accommodate the preferred flashing method on commercial roofs. It is installed on top of the site-built curb just like any other skylight. The 22″ diameter rigid tubing reflects up to 98% of the sunlight entering the round roof-mounted acrylic dome.

The amount of interior space illuminated by the TCR SUN TUNNEL™ skylight will depend upon the length of tubing, the sun orientation, and the geographical location of the installation. It is estimated that it can adequately light up to 150 – 400 square feet per unit.

Commercial-Sun-Tunnel2On large commercial projects, St. Louis Skylights and Velux can produce renderings and lighting simulations, resulting in a photometric analysis of the commercial space.

The commercial SUN TUNNEL™ skylight model is designed to be used in the following applications:

  • Commercial Offices
    • The commercial SUN TUNNEL™ skylight can be installed in suspended or hard ceiling systems on either flat roofs or low-slope roofs up to 30 degrees.
    • Round-to-square converter boxes can transition the round tubing into a square mounting within the ceiling structure.
  • Warehouse Spaces
    • A perfect solution to light large warehouse space using TCR SUN TUNNEL™ skylights by suspending them in open warehouse ceilings.
