Product details
Optimal transmission and distribution of light in space
The TCR commercial SUN TUNNEL skylight provides optimal transmission and distribution of light in commercial spaces by providing:
- 98% highly specular reflective rigid tunnel
- Excellent distribution of light by the prismatic diffuser at ceiling level
Easy and fast installation
The Model TCR can be installed quickly and easily:
Unique telescopic design of rigid tunnel (no vertical seam assembly required)
- Upper elbow designed to be adjusted from the roof
- Flexible bottom elbow allows for easy installation even at sharp offsets (flex elbow bends and does not significantly reduce aperture when offset)
Affordability
The commercial SUN TUNNEL skylight is the most cost effective way to light interior spaces.

Photometric analysis of commercial space |
- On large projects, VELUX offers assistance to architects with renderings and lighting simulations.
- Lighting software produces photometric analysis of commercial space
What to order?
The TCR SUN TUNNEL skylight is constructed as a modular system that allows you to purchase only the required components for your individual project.
- Distance is from roofline to ceiling. 12" have already been subtracted for curb height and flashing overlap with collar.
- Run length calculated based on vertical drop.
- Run length accounts for standard 2" overlap between components.
