Spray Foam Insulation Makes Your Home More Energy Efficient And Comfortable

Having the right amount of insulation in your home is important for your comfort and to keep your power bills low. If you live in an older home, it might be time to add new insulation. There are a few options for home insulation, and foam is a popular choice. Here's why foam insulation is a good choice for your home and how it can be used. 

Why Spray Foam Is A Good Choice

One of the main advantages of spray foam is that it can spread out as it swells to fill in holes and gaps. This helps prevent air leaks, which is one important function of insulation. Closed-cell foam insulation can also double as a vapor barrier and reduce the risk of water damage where it's installed.

Spray foam is even good for blocking sound, and it can be used on walls in home theaters to improve sound quality and block outside noise. When the foam expands and hardens, it can even add structural support to the surface it's on.

Where Spray Foam Can Be Used

Your insulation contractor can apply foam insulation to ceilings, walls, and floors. It can be used in your attic, in exterior walls, and in the crawlspace. Foam insulation is used in new construction and it can also be used in older homes without opening walls since it can be sprayed in wall cavities.

How Spray Foam Is Applied

The foam is sprayed out of a canister using a spray nozzle. It's a liquid at first, and then it turns to foam and expands. The foam has a noxious odor, so the contractor has to wear safety equipment when installing your new foam insulation, and you will probably need to leave the house while the work is being done and for several hours afterward.

The foam can be spread on walls because it gets hard so fast that the foam doesn't have time to slide down. If the foam is being applied to an exterior wall, the contractor will drill small holes in the wall and spray the foam in the wall cavity. After the foam fills the cavity, the holes are sealed. This saves you from having to tear open walls and replace the drywall.

Foam insulation is easy to install since it's similar to spray painting a wall or floor. The work should go quickly depending on how much insulation you're adding to your home. You may want an energy audit done before getting new insulation so you know exactly where it should go and how much you need.
