How We Spray Foam Insulation Under a Floor Without a Lot of Space

The floor of your home can be a source of comfort issues ranging from the obvious of cold floors to drafts in your home. You’re ready to add spray foam insulation to your home to eliminate moisture and/or improve the efficiency of your HVAC system, but there’s a catch – there’s not enough space under the floor for an installer to crawl inside. This happens if your crawl space is less than 18-inches in height or your home sits on a slab. 

The method to install spray foam floor insulation requires some pulling and cutting. It sounds scary, but it’s okay and the best way to ensure the floor cavity or small crawl space below is insulated properly.

There are two scenarios possible and they depend on whether you have carpet, tile or hardwood floors. Let’s talk about carpeted floors first. In order to insulate the space below your floor, the carpet will need to be pulled up. The installers will then cut one-foot access points to ensure the foam can be sprayed into the cavity below. Those strips are replaced, and the carpet is put back in place. We recommend having a carpeting company come back out to secure the carpet to the floor.

If there are wood floors in the home, then the process is slightly different. 

In this instance, the crew will cut at the tongue and groove of the wood floor to be able to cut the one-foot strips for access. The foam is sprayed into the cavities and the flooring is temporarily replaced. A flooring contractor should be hired to secure the flooring.

It’s important to note that while guests won’t notice the floor has been cut, the homeowner will notice a slight difference. While there could be this aesthetic difference, it solved the problems of cold floors and uncomfortable rooms.

Sealing up the space below your floor or tiny crawl space is just the start of taking back control of the comfort of your home. If you create an air seal by insulating the entire building envelope, not only will your home be more comfortable, it will also save you money on your monthly energy bills.

How you ask? It’s simple really, it’s because the air seal you create with foam insulation will prevent outside air from getting inside and the air you pay to treat will stay in your home.
