A Velux Sun Tunnel is an inexpensive and great way to light up your home. The installation time is about a half day for a standard job and a full day for a very difficult one. I recommend installing either the 10 inch ridged sun tunnel or the 14 inch ridged tunnel. The 10 inch tunnel brings in about 150-200 square feet of diffused light and the 14 inch ridged brings in about 325 square feet of diffused light. Take a look below at some of the specs that Velux has on their web site!
Highly reflective rigid tunnel
The TMR rigid Sun Tunnel Skylight features a highly reflective tunnel that provides brighter, whiter light output in any application. This makes the Model TMR great for most applications, even those with long tunnel runs or those in areas with less sunlight.
Pitched metal flashing
The TMR features an innovative one-piece pitched metal flashing that is designed to keep out the elements while providing the optimal angle for gathering light from all directions.
The TMR comes with a pre-assembled ceiling ring and paintable ceiling trim ring to complete any look.
Integrated flashing system
The standard Model TMR Sun Tunnel is designed for low profile roofing materials such as shingles and shakes. Tile flashing is also available.
The TMR Sun Tunnel installs on roofs with slopes between 15° (3:12) and 60° (20:12).
Warranties you can trust
Comes with a ten year warranty against manufacturer's defect, rust corrosion and deterioration.
