Also called light tubes or solar tubes, VELUX SUN TUNNEL skylight windows bring natural light into even the darkest and most isolated spaces through a specially designed tunnel that passes from roof to ceiling. Our solar tubes are great for homes and businesses in the Chicago area.

Adding a SUN TUNNEL™ skylight window is a cost-effective way to add natural light to small spaces such as powder & laundry rooms, kitchenettes, hallways, or other tight spaces that need a brighter, more vibrant appearance. Their low-profile design creates a sleek appearance on any roofline, and their pre-fabricated solar tubes makes them quick and easy to install. Not to mention, they come with a 20-year tube warranty.


Flexible Solar Tubes

Flexible solar tubes are recommended when installation around obstacles within the loft space is required. They are the easiest product to install because of the maneuverability of the material.

  • Excellent for ease and speed of installation
  • Easily bends around attic obstructions

Rigid Solar Tubes

Rigid solar tubes are recommended when there is a straight, unobstructed path from the roof to the ceiling, although they can be maneuvered slightly.
