Duct leakage may be causing your
indoor air quality problems.
A good transmission gets
power to all the wheels of a car. Just like a good air
duct system gets air to all the rooms of your home.
The problem with leaky
ductwork is that air can not only leak out of
you HVAC system and air ducts -- untreated and unclean air and
contaminants from the crawlspaces, attic and other place can
actually be pulled in to the air you and your
family breath.
Since so many air duct
systems leak and pull bad air in (we find 20 to 40% leakage in
3 out of 4 homes we visit), poor air quality is a problem that
many homes have.
Here's what independent
utility companies, researchers and government officials are
publishing about how Aeroseal fixes the problem of leaky ducts
and poor airflow ...
Improved Duct Sealing
ASHRAE Journal (Oct
2003)
"Nothing is certain but death and taxes - and perhaps leaky
ducts."
A New Comfort Remedy
Built Green® Articles (July 26, 2002)
"This time of year the airwaves are filled with ads urging you
to get your ducts cleaned. Your ducts are your home's lungs,
they say, so why wouldn't you clean them? Yet if comfort is a
problem in your home, its more important to seal your ducts
than it is to clean them up.
Virtually every home's
ductwork leaks. According to LBNL, typical duct systems lose
25 to 40 percent of the heating and cooling energy put out by
the furnace or air conditioner. Field observations by
contractors working with Energy Rated Homes of Colorado
generally support LBNL's claim."
Do a Spring Cleaning on Your Energy Bills
The Street.com (April 2002)
"For those who want a perfect seal in hard-to-reach places,
EPA's Rashkin recommends a brand-new product called Aeroseal,
which seals ducts from the inside out, just as the sprays used
for flat tires do."
Duct Tightening
California Energy Department (2001)
"Innovative materials and
processes are being introduced to the marketplace by Aeroseal,
Inc. Testing techniques and qualified contractors to verify
leakage levels are becoming more available due to demand
created by the residential duct sealing provisions in the
standards and the inclusion of duct sealing in the AB 970
process."
Weatherization Test Drives Spray Sealant
Home Energy Magazine Online
(Nov/Dec 2001)
"Until recently, duct-sealing
methods have not gotten enough attention from building
scientists. Aerosol spray sealant offers a relatively new way
to seal ducts--one that is becoming commercialized in some
parts of the United States (see "Aerosol Spray Technology").
One advantage of this technology is that it reduces diagnostic
and repair times, because the location of small leaks does not
need to be visually identified, and wall, ceiling, and floor
cavities do not need to be opened to gain access to the leaks.
Aerosol spray can seal small or unreachable leaks that cannot
be sealed in other ways."
Las Vegas Contractor Tackles Leaky Ducts
IAQ News (Oct 2001)
"WHY TAPE DOESN'T WORK -
For three months, LBNL researchers tested a variety of sealing
materials -- many kinds of duct tape, clear plastic tape,
foil-backed tape, mastic, and injected aerosol sealant --
under conditions similar to those encountered in installed
hvac systems. Of all the products tested, only duct tape
failed. In fact researchers said that "It failed reliably and
often quite catastrophically."
