Our Underfloor Insulation Services

Insulation is seldom a “one-size-fits-all” project, and underfloor insulation is no exception. We can install many insulation varieties in your crawl space, including:

Spray Foam Floor Insulation

Polyurethane spray foam insulation is quick to install and highly effective for insulating crawl spaces. As you may expect based on its name, the installation process for spray foam insulation involves spraying it in areas that need to be insulated. After we’ve sprayed this foam, it expands to a much larger size.

Blown-In Floor Insulation

Often (but not always) made from cellulose, blown-in insulation is ideal for floor insulation. That’s true whether you’re insulating an attic floor or the crawl space under floors in your home. Our team has access to industrial blowing machines, allowing us to install this insulation before you know it.

Batt Floor Insulation

Fiberglass insulation is another viable option for insulating your crawl spaces. Batt insulation, which takes the form of pre-made panels, is perfect for this job. We can put these panels in while using the proper protective gear to prevent any health risks.

Ventilated And Unventilated Crawl Space Insulation: Know The Difference

In the process of installing crawl space insulation, there’s another factor to keep in mind beyond the type of insulation you prefer. Your crawl space’s ventilation can affect where you need insulation.

For ventilated crawl spaces, it’s best to install insulation under subfloors and between floor joists. Meanwhile, unventilated crawl spaces don’t need quite as much insulation as ventilated spaces do. However, you’ll still want to have their walls insulated.

Are you unsure whether or not you have a ventilated crawl space? If so, there’s no need to worry! The employees of SATX Spray Foam Insulation will be able to figure this out for you well before the job starts.
