What size do they come in?
14-inch diameter fits between 16" on center.
22-inch diameter fits between 24 " on center.

What's included in the kit?
The dome, flashing, tubing, hardware and everything needed for a complete roof-to-ceiling installation (including step-by-step instructions.)

How much tubing comes with each unit?
Each unit comes standard with six feet of tubing. If you need more tubing, please contact your dealer.

What is the tubing and dome made of?
The tubing is a double layer of metalized polyester film with a double inner layer of reinforced aluminum Sola-film with a highly reflective ultraviolet-proof laminate. The dome is made of UV Stabilized Grade-One Acrylic. By improving upon the flexible tube technology used for years in the heating and air-conditioning industries, we've created a way of bending sunlight around attic obstructions and the most cost- and-energy-efficient skylight system available in the United States.

What is your warranty?
The Sun Tunnel comes with a seven-year manufacturers warranty.

Will The Sun Tunnel fit all roof types?
Yes, but tile roofs require a special order through your dealer.

How much light does The Sun Tunnel produce?
The 14-inch diameter is best for lighting up bathrooms, halls, walk-in closets and areas up to 10' x 10'. The new 22-inch diameter Sun Tunnel is perfect for lighting kitchens, bedrooms, living areas and other rooms up to and over 25' x 25'.

What are the advantages of the Sun Tunnel's patented Flexi-Tube?
The Flexi-Tube combined with The Sun Tunnel's larger diameter channels light for longer distances and more economically than non-flexible tube skylights. Every Sun Tunnel comes with six-feet of flexible tubing. Additional tubing, if you need it, is available by calling your dealer.

Is the Sun Tunnel energy-efficient?
Yes! Thorough testing indicates that there is no appreciable heat gain or loss with the Sun Tunnel. Complete test results are available from your local dealer.

How does the Sun Tunnel look on my roof?
We think The Sun Tunnel is the most beautiful thing you can put on your roof. Then again, we're kind of biased, aren't we? The Sun Tunnel's low-profile plastic dome installs on your roof and catches sunlight from all directions -- even on cloudy days. A circular diffuser softens and evenly distributes the light coming into your house.

Will the Sun Tunnel help my plants?
Full-spectrum sunlight has been growing forests and flowers for millions of years.
Because it captures sunlight from all directions and provides it all day long, the Sun Tunnel is the best gift you can give to your plants. (Besides talking to them.)
