Insulation for Attic

The two guys did an excellent job and allowed me to review and look at each step of the process - great workers! After a horrible experience with flooring installation my faith is restored in Home Depot Installs.

Polite installers; timely completion of job

It seems that the insulation has improved the efficiancy of the A/C unit. We are able to achieve the desired temperature now in a shorter period of time and the A/C has not frozen up on us on these 100 degree days.

Frequently Asked Questions

Answers to common attic insulation questions

How important is it to properly insulate my house?

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.

What is the R-value?

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.

Does insulating the ceiling force more heat to leak out of the windows?

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.

Will stuffing thicker insulation into a smaller space increase its R-value?

Fiberglass insulation works like trapped air pockets. Compressing the insulation actually decreases the amount of air trapped and reduces its R-value and effectiveness.

Will fiberglass insulation promote mold growth?

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.

Attic Insulation Helps Reduce Cost

More than 90 percent of homes in America lack adequate attic 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. Installing insulation with the right R-value can also make a big difference, be well worth the cost savings, and help you enjoy more comfort year round.

Ready to stop wasting energy but don’t know how to install insulation?
