Benefits Of Spray Foam Insulation For Your Attic

Fiberglass batt insulation was often a traditional choice for attic insulation in older homes. Today, you have a wider variety of choices that provide superior insulation. Spray foam is one option that is a good choice for new construction and older homes too. If you want to improve the insulation in your attic and hopefully lower your power bills too, then you may want to replace your fiberglass insulation with spray foam. Here are some benefits of switching.

Foam Insulation Is Waterproof

There are two types of spray foam insulation. Closed cell foam is the most dense, and it provides the best barrier against water leaks. When spray foam is sprayed onto your attic floor, it expands and then hardens. If your roof develops a leak, the insulation won't be ruined, and it may even prevent the water from dripping on through to the ceiling below. Fiberglass on the other hand, is destroyed when it gets wet. It compresses and loses a lot of its insulating ability. Plus, it takes a long time for it to dry out, so it may stay damp all the time, which leads to the growth of mold and musty odors wafting from the attic.

Foam Blocks Air Leaks

Foam insulation blocks air leaks and drafts. The problem with fiberglass batt insulation is that it has a defined shape that can't fit snugly against corners and uneven spaces. Spray foam goes on like a liquid so it flows into all the nooks and crannies in your attic. It molds itself around pipes and other protrusions so all the air leaks are sealed. If you have tiny cracks or other leaks in your attic floor, the foam will seal them so frigid air won't leak into the lower floors in the winter to create cold drafts.

Pests Aren't Drawn To Spray Foam

There is nothing in spray foam that attracts insects. It doesn't contain any wood or natural fibers, and it dries to a hard surface. Therefore, you won't have to worry about rats, insects, and other pests tearing up the insulation. Pests don't eat fiberglass insulation, but it makes perfect bedding for them. Rats and bugs will build nests in the fiberglass if they get in your attic. Squirrels may tear the fiberglass to shreds so they can take pieces out of the attic to their nests in the trees. What's worse, when rats, squirrels, or raccoons get in your attic and nest in the fiberglass insulation, it holds onto their droppings and urine. This makes your attic smell bad and the foul odor can spread throughout your home. You can eliminate all these problems and make your attic less attractive to pests by going with spray foam.

Applying spray foam insulation to your attic is quick and easy for a contractor to do. It is similar to spraying on paint or using a pressure washer. After it is sprayed on, it will expand for several minutes and then begin to harden. It will take about a day for it to fully dry and then your attic will be ready to protect your home from frigid winter weather.
