Installed Insulation Frequently Asked Questions
10-25-2016
Q: How important is it to properly insulate my house?
A: More than 90 percent of homes in America lack adequate attic insulation and wall insulation, which
can increase monthly energy bills and reduce comfort. Adding house insulation with the right R-value
can make a big difference.
Q: What is the R-value?
A: R-value refers to the insulation's ability to resist heat flow and keep your home's temperature better
controlled. As the R-value increases, the strength of the insulation also increases. Recommended R-
values change based on where in the house you're adding insulation, if the area of your home has been
previously insulated or not, and where you live. For example, an uninsulated attic in Alaska should have
insulation installed with R-values 49-60, whereas an uninsulated attic in Hawaii only needs insulation
with R-values 30-49 installed.
Q: Does insulating the ceiling force more heat to leak out of the windows?
A: Adding insulation to one part of a house won't increase the "pressure" on heat losses through other
parts, but poorly insulated areas will continue to be major sources of temperature fluctuation in a home.
Q: Will stuffing thicker insulation into a smaller space increase its R-value?
A: Fiberglass insulation works like trapped air pockets. Compressing the insulation actually decreases the
amount of air trapped and reduces its R-value and effectiveness.
Q: Will fiberglass insulation promote mold growth?
A: Fiberglass doesn’t hold water very well unless it is soaked and it does not provide food for biological
growth. Fiberglass becomes dirty when unclean air and dust flows through it, not because of mold.
Q: Why do I need Attic Insulation?
A: More than 90 percent of homes in America lack adequate attic insulation and house insulation. But
here’s the good news: according to the Department of Energy, a properly insulated attic can save you
anywhere from 10 to 50 percent on your energy bill, so we’re not just blowing hot air. Adding house
insulation with the right R-value also makes a big difference, be well worth the cost savings, and help
you enjoy more comfort year round.
Q: What do I need to do to get started?
A: Determine the amount of insulation you need by measuring your square footage and the R-value for
your area, then make the purchase. One of our representatives will call to schedule your installation at
a time convenient for you.
