What is a tubular skylight / Sun Tunnel, solar powered sky light
tube?
A Tubular skylight is a product that transfers natural sunlight
into useable light that lightens up dark rooms. The technology used to
accomplish this is a super reflective light shaft and precise engineered
diffusers.

Why use a sun tunnel tubular skylight?
A sun tunnel tubular skylight efficiently provides pure natural light
while effectively minimizing heat gain and heat loss since it is a
sealed system. Tubular skylights eliminates dark rooms. There are many
benefits of living in rooms illuminated with natural light. Get rid of
those dark room blahs for good! Plants thrive in rooms lit with natural
light as well.

Will the sun tunnel tubular skylight work on cloudy days?
Sun tunnel tubular skylights reflective system transfers light
down to the room with minimal light loss on cloudy days. The engineered
diffuser and state of the art optic technology incorporated into the
light pipe allows light coming from any direction to be transferred down
the tube, allowing the best light output possible.

Is the dome material durable?
The sun tunnel tubular skylight dome is extremely durable. In fact, it passed the most
stringent skylight test in the country-the Florida hurricane
impact test! The dome had to endure a direct hit from a 9 pound 2x4
traveling nearly 40mph and not leak one drop of water when subjected to
130mph winds and gushing rain water! The modified acrylic dome does not
fade and weaken after years of exposure to the sun's UV rays.

Is placement on the roof important?
The best location for any solar device would be on the southwest facing
side of the house. Remember to take into consideration chimneys,
adjoining roof structures or trees-anything that can cast a shadow over
the dome is going to effect the light output. There is so much light
energy in sunlight and the Natural Light Tubular Skylight does work well
on the north side of a house. Just keep in mind that the best light
output is obtained by exposing the dome to direct sunlight. Therefore it
performs better where it receives as much direct sunlight as possible.

How long can the tube be?
In general, the ideal length of tube is about 6 feet. However, lengths
over 15 feet are routinely installed with very favorable results. We
recommend increasing the unit to the next size for runs longer than 14
feet.

Are sun tunnel tubular skylights energy efficient? Do they allow heat in or out
of my home?
Sun tunnel tubular skylights are extremely efficient; with virtually no heat gain
or loss, they are also Energy Star rated and qualify for both state and
federal tax credits.

Do sun tunnel tubular skylights leak?
Sun tunnel tubular skylights are seamless, therefore, providing that
they are installed in accordance with the manufacturer's directions,
they will not leak!

How long does it take to install a sun tunnel tubular skylight?
Typical installation by a homeowner is about 2 hours with common
everyday tools.

Can I install a tubular skylight if I I have a cathedral ceiling?
Yes! Natural Light manufactures a tubular skylight flashing designed
just for cathedral ceilings making the installation a breeze. Please
order a "FLAT" flashing for this purpose.If you are purchasing
a VELUX sun tunnel please order the "TGR" model.

Do I have to insulate my light pipe? Condensation?
No you do not have to insulate the light pipe. The system
is designed to weep out any condensate that occurs and it works very
effectively. In northern states please use the free optional soft
diffuser which creates a double insulated diffuser and further protects
the unit from large temperature differentials thus less condensation.

Do I need a thermostat on my solar attic fan?
Typically you do not need a thermostat for the proper operation of your
solar attic fan. The solar attic fan exhausts the moisture that is
trapped in your attic space that comes from the heat sources in your
home as well as the environment. Moisture does far more damage to your
roof structure than heat; ice dams and mold formation are the two major
problems. I recommend using a thermostat if you live in a dry area, like
the desert.
Back to Top
Where should I install the solar attic fan on my roof?
The solar attic fan should be installed on a south or west facing roof.
It should be located in the center of the roof and about three feet from
the ridge of the roof.

Will the solar attic fan make noise?
The solar attic fan is so quiet you will not hear it run from a distance
of about three feet!
