When you want to add new insulation to your home, you have different options to consider. After looking at the advantages and disadvantages of each type of insulation, you might decide that spray foam is the best choice for your needs. Spray foam not only insulates, it also seals gaps without harming pipes or electrical wiring. Here are some ways you can use spray foam insulation to improve the energy efficiency of your home.
Add Foam Insulation To Exterior Walls
It's possible for a spray foam installation contractor to insulate your home's exterior walls without having to take drywall down to access the wall. Instead, the contractor can drill holes in the wall and inject the spray foam through them. The foam will expand inside the wall cavity and form a barrier that prevents air leaks. Spray foam insulation on exterior walls can also help with sound control to muffle outdoor noises, and since the foam isn't an organic food source for mold, you don't have to worry about it getting wet and moldy when it's hidden between the walls.
Use Spray Foam To Seal A Crawlspace
If you have problems with a wet crawlspace, then sealing the space could be a good solution so moisture, odors, and bugs don't enter your home from below. Sealing can be done with spray foam on the walls and ceiling and using a vapor barrier on the floor. By keeping the crawlspace dry, you'll reduce the risk of musty odors rising through the floor of your home. You might also reduce the risk of mold and mildew in your house as well as the crawlspace below.
Apply Spray Foam In The Attic
One of the most common uses for spray foam insulation is in the attic. Spray foam is ideal for attic insulation because the foam can spread over surfaces to fill cracks that allow rain to drip in. Foam also prevents gaps around the edges of the insulation so your attic floor has the best coverage. Foam lasts a long time, too, and if your roof develops a leak, you don't have to worry about the rain affecting how well the insulation works like you do with fiberglass or cellulose.
Installing spray foam insulation is not a disruptive process either. The contractor usually keeps the chemical tanks on a truck parked outside your home and pumps the solutions through hoses to your attic or other work area. The foam is sprayed on through a nozzle, much like spray painting your house. However, applying the foam requires training and experience so the right thickness and uniformity is achieved.
Spray foam insulation might cost more than fiberglass, but it also provides better insulation for your home, so the expense is usually worth it. Improving the insulation in your home could make you more comfortable in the winter or on a hot summer day.
