Q: Can I see the MSDS
sheets that relate to Aeroseal air duct sealing?
A: Yes,

Q: Is
the sealing material used by the Aeroseal air duct sealing system safe?
A: The vinyl polymer is
safe, using the same base material as used in chewing gum
and hair spray. Aeroseal's sealant is UL tested and approved.
In the over 10,000 seal jobs we've completed to date and have
not had an issue with safety. As a conservative
precaution, we do recommend that people with chemical
sensitivity to vinyl, pregnant women and people with serious
medical conditions to leave the building when sealing is being
performed.
Q: Tell me more about safety. Has a
study been done by scientists?
A: In
December 1998, Lawrence
Berkeley National Laboratory (LBNL) published a study
regarding Aeroseal's process.
Here is an excerpt from the LBNL
report on Aeroseal safety:
"The material typically used in Aerosol sealing
techniques does not appear to present a health or safety
hazard."
The LBNL report goes on to say:
"Assessment of duct sealant health and
safety hazards (EPA)...
This project
looked at the potential health and safety hazards associated
with the Aeroseal product ... This report concluded that the
materials used in the Aeroseal
system are not a significant health or safety hazard."
Q: Does
the sealant leave an odor?
A: The Aeroseal air duct sealing
process leaves no lingering odor, and since the material does
not put off gas over time, there will be no odor for the life
of the product.
Q: Can
the Aeroseal air duct sealing system reduce the amount of dust in my
home?
A: Ductwork runs through
attics, crawlspaces, basements, garages, and walls. Leaking
return air ducts pull in dust and other indoor air pollutants
and sends them to the central heating and cooling system.
From there they sent to the living areas of your home. The
Aeroseal air duct sealing system can reduce the amount of leakage by
as much as 90%, reducing dust and other indoor air pollutants
from the conditioned air in your home.

Q: Is the sealing
guaranteed or can I get my money back? What if it doesn't
work?
Aeroseal provides a 10-year
warranty on the seals
created with our process. We have enormous confidence in the
quality of our seals since they are based on Lawrence Berkeley
National Laboratory research and a patent through the
University of California. The EPA has endorsed Aeroseal, as
have numerous local energy utilities. Note: the warranty is
for on-site seal failures and does not cover additional damage
(e.g. an electrician that steps on a duct while running
wiring), wear or tear (i.e. the shelf life of a plastic duct
is passed, rodents eat into a duct, or a duct rusts out), and
subsequent replacement of failed ducting.
Overall, in the 9000 plus seals done to
date, we have yet to receive any warranty claims.
