An
effective attic ventilation system is a fundamental concern
every
month of the year.
Most homeowners believe the principal purpose of attic
ventilation is to remove heat from the attic in the summer. That’s true.
But attic ventilation also removes damaging moisture in
the winter.
During the heat of the summer, ventilation helps keep
attics cool. During the cold winter
months, constant airflow in the attic reduces potentially damaging moisture. Properly ventilating attics is an essential
precaution to protecting the long-term well-being and value of your home.
The
integrity of roofing and insulation performance is directly related to the
effectiveness of attic ventilation:
When inadequate attic ventilation exists, insulation no
longer can compensate effectively for temperature extremes. Studies have shown that the dynamics of air
movement throughout a house usually produces moisture in the attic, where it
condenses on rafters and roof decking.
Left unchecked, this condensation can saturate the roof, attic
floorboards, insulation, and even walls and ceilings.
A high-efficiency ventilation system helps
solve attic moisture problems by allowing a uniform flow of air to sweep the
underside of the roof sheathing. In
higher heat, this ventilation system will exhaust hot air from the attic
reducing the temperature in the home’s living spaces. In colder weather, it exchanges warm, moist
air with cooler, drier air. In both
cases, the result is greater living comfort, less energy use and less structural
damage.
Efficient
insulation increases the need for effective ventilation.
Heavier
insulation holds and absorbs more heat resulting in overwhelming attic heat
buildup. On hot days the upper rooms
of a home are always warmer. In most
homes, the lack of adequate attic ventilation actually causes the downward flow
of heat. With an unventilated or
inadequately ventilated attic, the longer the hot weather persists, the more
uncomfortable (or unbearable) the home becomes because the heat loss overnight
insufficiently compensates for the heat gained during the day. Ultimately, this heat accumulation costs
homeowners more to operate their air conditioning units and fans, a problem
further magnified during these times of rising energy prices and black out
periods.
Homeowners today have a variety of choices for
ventilating their attic. The three most predominate systems are:
passive systems
electric-powered systems
solar-powered systems
Solar-powered
systems are the most versatile and efficient ventilation system. Solar-powered units do not need breezes, but
do require locations that receive adequate sun exposure for peak operational
performance.
Like
traditional attic fans, solar attic fans remove hot, stagnant air from your
attic which allows your air conditioner to more efficiently cool your house –
cutting your energy costs up to 30% while extending the life of your HVAC. What
makes solar attic fans even better is that they require no electricity. That
means not only are your operational costs zero but installation is wire free
and a breeze!
As the inventor of the original solar attic fan,
SunRise Solar has proven to be an industry leader for over 10 years.
SunRise Solar attic fans are almost undetectable. With a sleek design
for every rooftop, solar attic fans blend seamlessly into your roofline. And
unlike an electric attic fan, they are extremely quiet. If it wasn’t for the
energy savings, you might forget it’s there.
SunRise
Solar's fans have been named "Best Product" by BUILDERnews Magazine
and "Most Valuable Product" by Building Products Magazine two years
in a row.
SunRise
Solar attic fans are made out of UV stabilized ABS plastic - the same material
used on car bumpers, kayaks, motorcycle helmets, playground equipment and much
more. It's completely noncorrosive, heat and flame resistant and can withstand
environmental abuse that metals cannot.
