If you live in a home that has a crawl space instead of a basement, you may be planning on cleaning up the space and sealing the entry points to help keep air and water out from underneath your home. As part of your efforts, you may be planning to install insulation but are uncertain as to what type of insulation you should use. If so, consider a couple of the reasons why you should choose spray foam to insulate the crawl space under your home.

1. Creates a Tight Seal along the Walls of the Crawl Space, Keeping Drafts from Coming up Through the Floorboards

One reason why you should choose spray foam over other types of insulation for your home's crawl space is that it will create a tight seal along the walls. This tight seal it creates will be airtight, unlike fiberglass or blown-in insulation that often leaves openings.

Because the spray foam creates an airtight seal, the outside air will not penetrate the barrier and flow underneath your floorboards. This helps to keep drafts from coming up through the boards and into your home, helping to keep the temperature inside more consistent and reduce the strain on the heating and air conditioning systems.

2. Acts as a Barrier to Keep Moisture away from the Floorboards and Wooden Posts, Preventing Rot, and Termite Infestation

Another reason why spray foam should be your choice for insulating your home's crawl space is that it creates a moisture-resistant barrier. Unlike other types of insulation that can soak up water infiltrating through the foundation, spray foam will block it.

Because of this barrier, your home's floorboards and their supporting wooden posts stay dryer, which helps to keep them from rotting. Keeping the wood dry and preventing deterioration also prevents conditions that can attract termites, which can help protect your home from an infestation.

When you insulate your home's crawl space with spray foam, the airtight barrier it creates can keep your home cooler in the summer and warmer in the winter by keeping drafts from coming up through the floorboards. The foam also acts as a barrier from outside moisture that helps to preserve the structural integrity of the floorboards and their support posts and helps prevent termite infestation that often comes with wet, deteriorating wood.
