What is the installation process for a Sun Tunnel®?

1 min. readlast update: 10.17.2023

Installing a VELUX Sun Tunnel® happens in three phases.

  1. The Attic First, your installer will go into the attic to check rafter locations, take measurements, and mark off where the ceiling and roof holes will go.
  2. The Rooftop Up on the roof, your installer will cut a hole and install the top collar, the upper portion of the tunnel, lens, and flashing. 
  3. The Interior Back inside, your installer will cut a hole in the ceiling and install the lower portion of the reflective tunnel to connect the two holes and seal the tunnel seams. Next, they'll install the diffuser and trim ring in the ceiling. 

Then, if the sun is out, your new light will be on!
