Your home needs to be insulated well when you want your HVAC to perform efficiently and keep the temperature in your house comfortable. The insulation you already have may not be adequate. Even if your attic has plenty of insulation, the crawlspace and exterior walls may need more, especially if your house is old.

When you compare options for new insulation, you may find spray foam is the ideal choice. Here are some advantages of foam insulation and a look at how it's installed.

Advantages Of Getting Foam Insulation

Foam insulation is sprayed on, so the liquid can flow into odd shapes, expand into foam, and harden to form a blanket-like barrier on walls, floors, and ceilings. The foam plugs air leaks and blocks heat transfer, so it performs the two important tasks of home insulation with a single application.

Some types of spray foam are watertight, and all types become hard as they dry to add structural support to walls and floors. Since the foam is hard and not made of fluffy materials, there is nothing to attract rodents or insects, so you may find you have fewer problems with pests in your attic when it has foam insulation.

Installation Methods For Foam Insulation

Foam can be sprayed between walls, so it isn't necessary for the wall to be open to have the insulation installed. This requires holes drilled in the walls, but the holes can be filled and painted so they disappear when the work is done. This type of insulation is only used on exterior walls unless you want to add it to interior walls to muffle the sound for a media room.

Foam insulation can also be used in a crawlspace. It's a good accompaniment for crawlspace encapsulation that keeps your crawlspace dry while improving insulation. Foam is also a popular option for attics where it can be sprayed on the floor, walls, or ceiling of your attic to help control humidity and heat transfer.

The spray comes out as a liquid. The liquid comes from two separate tanks, and when the liquids mix together, a chemical reaction forms that causes the liquid to turn to foam. The installer can control the thickness of the insulation so that you have the amount of insulation needed for your climate.

Spray foam isn't as easy to apply as it may look, so you'll want a professional to install your new insulation. Plus, the fumes can be toxic until the insulation is dry, so it's essential to take precautions when applying the insulation. You might even need to leave your home until the work is done and the odors have left.
