Crawl Space Insulation

Crawl Space Insulation & Encapsulation Solutions Throughout North America

Ward off mold & moisture damage and boost indoor air quality with the right crawl space insulation

Crawl space insulation is important. A number of comfort and energy problems can be caused by poor quality crawl space insulation.

In addition to installing the right type and correct amount of insulation, it is also important that the insulation be installed correctly. The crawl space can be wet and damp, so the insulation installed must be able to hold up in these conditions.

The experts at Spray Foam Comfort will inspect the crawl space, seal air leaks, and install high-performance insulation to help improve the comfort and energy efficiency of homes large and small, from Southern California to Florida. 

crawl space

Crawl spaces, especially those with dirt floors or moisture problems, are wet in summer and cold in winter! Crawl space wall and floor insulation can solve all that!

Indicators of crawl space insulation issues:

  • The floor above the crawl space is unpleasantly cold in wintertime.
  • During cold weather, you have to keep the heat going nearly all the time to be comfortable in rooms directly above the crawl space.
  • Mice or other pests have taken up residence in fiberglass insulation installed between joists in the crawl space.
  • Fiberglass batt insulation has fallen out of place from between floor joists in the crawl space.
  • The crawl space smells moldy or has visible signs of mold.
  • The crawl space is damp all the time.

Many homes all across America, have the wrong type of crawl space insulation, if any at all. The old-fashioned way to insulate a crawl space was to install fiberglass batt insulation between joists and vent the crawl space so outside air could circulate beneath the house.

Unfortunately, this combination generally leads to the problems listed above. Fiberglass insulation doesn’t respond well to the moist conditions that can be found in a crawl space. It can be like a sponge, and soak up the moisture, making it near worthless as an insulator.

The cotton-like material absorbs moisture, gets soggy, compresses and loses R-value. Fiberglass batts often end up on the crawl space floor in a soggy mess. The main advantage of fiberglass insulation –low cost—is totally negated when the material ceases to perform its main function.

Benefits of Rigid Foam Crawl Space Insulation In Your Home

  • Secure and dependable. Unlike fiberglass insulation, rigid foam won’t compress, fall out of place or lose its R-value over time. It’s definitely a “once-and-done” improvement.
  • Efficient air sealing. When joints between foam panels are taped, rigid foam stops air leaks that can waste energy. Fiberglass insulation can’t stop air movement.
  • Moisture-proof. Rigid foam won’t absorb moisture or be damaged by it.
  • Resistant to mold. Mold can’t take hold on rigid foam because it contains no organic food source and it doesn’t hold moisture.
  • Improved ductwork performance. Ducts located in the crawl space benefit from rigid foam installed against crawl space walls.

Versatile Energy-Saver 2-part spray foam expands after it's applied, creating an effective thermal and moisture barrier. Due to its unique properties, it can be used to solve comfort & energy problems in many areas of the house.

Rigid foam panels exceed fiberglass performace in the crawl space

Rigid foam insulation performs exceedingly better than fiberglass in a crawl space. Rigid insulation is manufactured in panels of different thicknesses. Installers cut the panels to fit against the interior face of crawl space foundation walls. Panels are attached with adhesive or mechanical fasteners.

We typically insulate crawl space walls with foam board insulation. This brings the crawl space inside the building envelope, which improves overall home energy performance. This will also help make rooms above the crawl space more comfortable and can help lower heating and cooling bills.

Although rigid foam insulation is more expensive than fiberglass insulation up front, it’s actually less costly over time when you consider that you’ll never have to clean up or re-install a jumble of damaged, ineffective installation. Rigid foam will deliver the same performance and benefits years down the road as it does on day one.
