For a Better Environment--Inside.
According to the EPA, indoor environments can be 3-5 times
more polluted than the outdoors--and
Americans are spending 90% of their time indoors on average.
The EPA has also listed poor indoor environmental quality as a
top-five health threat.
Now for the good news. You can improve your IEQ (Indoor
Environmental Quality) by installing insulation.
Air Quality
Many fiber glass building insulation products are
certified by the GREENGUARD
Environmental Institute as low emitting building materials,
providing independent third-party assurance of their low Volatile
Organic Compound (VOC) emissions.
Less Indoor Noise
Did you know an efficient way to reduce noise in a home or
building is by adding insulation? Insulation is one of the best
building materials on the market today to absorb sound and reduce
outside or room-to-room noise.
Condensation Control
Fiber glass insulation with a vapor retarder facing helps
prevent condensation. The vapor retarder acts as protection against
the flow of moist air through the insulation, where it can condense
and lead to mold and corrosion problems within the structure. Fiber
glass insulation can help minimize potential condensation problems
in attics, floors, and walls.
Controlling moisture is critical to a healthy indoor
environment. In addition to insulation: sufficient ventilation must
be designed into the home to reduce excessive water vapor build-up
within the home.
Ventilation of building sections is necessary so that
excessive water vapor is dissipated to the outdoor air.
Construction materials should limit water vapor transmission
into building cavities.

Think about breathing easier.
Insulation significantly reduces energy consumption, as
discussed elsewhere in this site. This impacts our pocketbooks and
our environment - but also our health on a personal level. Energy
saved greatly reduces the amount of sulfur oxide, nitrous oxide and
fine particle matter that is released into the atmosphere from
power plants. So, increasing insulation levels means thousands of
fewer asthma attacks and respiratory ailments each year according
to a recent
Harvard
study.
These emissions reductions would also result in fewer
restricted activity days per year (days in which an individual is
not able to do their normal activities because they are feeling
sick due to pollution-related illnesses).
