Crawl Space Spray Foam Insulation for Your Home or Commercial Building

Crawl spaces are often easily forgotten about and even avoided as they can be dirty, cramped, and even full of bugs and other critters. However, when it comes to your building or home insulation, crawlspace insulation is essential. At KC Spray Foam & Coatings, LLC, our expert commercial and house insulation technicians understand how essential proper crawlspace insulation is in keeping your home or building efficient and comfortable. We are proud to provide our customers with quality crawlspace spray foam insulation services.

The Importance of Crawl Space Insulation

Adding proper crawl space insulation is one of the most effective ways to improve your home or commercial building’s energy efficiency. A poorly insulated or uninsulated crawl space will allow cold air in the winter and warm, humid air in the summer to enter your home or building, forcing your HVAC system to work harder, costing you more in utility bills. Installing spray foam insulation to your crawl space is one of the best places to add spray foam and will yield the most noticeable, instant results.

In addition, adding crawl space insulation will help prevent moisture from being drawn up into your home or building, reducing the chances of mold, mildew, or fungi growth.

Why Use Spray Foam Insulation in a Crawl Space?

Crawl spaces have historically been difficult to insulate until spray foam insulation came along. The traditional thought has been to insulate the floor of a crawl space with fiberglass insulation and then to vent the crawl space area. The idea was to give moisture, mold, and radon a way to vent out. However, using this method allows moisture to enter the house through fiberglass insulation and creates a perfect environment for mold growth.

Building science and years of testing has now taught us differently. The best crawl space insulation practice is to insulate the exterior walls of the crawl space and to install a 6 mil vapor barrier plastic on the floor, sealing the edges, and overlap with spray foam insulation. This is what is called a conditioned crawl space, essentially turning into a conditioned space.

Benefits of Crawl Space Insulation

In addition to improving your home or commercial building’s energy efficiency and lowering your utility bills, crawl space spray foam insulation also comes with a variety of other benefits including the following:

Thwarts Pest Infestation

Since crawl spaces are often dark and unoccupied, they make for a perfect home for ants, cockroaches, wasps, mice, and numerous other pests. An uninsulated crawl space makes it extremely easy for these pests to enter your home or building. While crawl space and home insulation will not completely get rid of pests already occupying the space, it can help prevent future pest infestations.

Improves Indoor Air Quality

A poorly insulated or uninsulated crawl space can allow pollen, dirt, mildew, and other outdoor contaminants to spread throughout your home or building, compromising your indoor air quality. By adding proper crawl space and building/house insulation, you will enjoy enhanced air quality and a cleaner indoor environment.

Prevents Pipes from Freezing

Frozen pipes during cold winters are a common occurrence for home and building owners throughout the greater Kansas City area. Not only are frozen pipes a hassle to deal with, but they can also end up costing you a good deal of money. Adding sufficient crawl space and building/house insulation can help save you the headache of burst pipes and water damage.

FAQs About Crawl Space Spray Foam Insulation

What type of spray foam is best for crawl space insulation?

Due to its moisture-resistance and high R-Value, closed-cell spray foam is often the best insulation choice for dark, damp areas, and therefore works exceptionally well in crawl spaces.

Instead of adding crawl space insulation, can I just add spray foam insulation to the underside of the floor?

At KC Spray Foam & Coatings, LLC, we always recommend adding crawl space insulation. Insulating the floor underside with spray foam insulation does nothing to add to the thermal performance in your home or building, plus it adds unwanted costs to the project.
