Crawl Space Insulation

Greater Charlotte's Premier Crawl Space Insulation Contractor

In this video, Dr. Energy Saver solves home comfort problems caused by an unsealed, uninsulated crawl space. Watch to see how to make your crawl space more energy efficient!

Many homes have the wrong type of crawl space insulation

Signs of crawl space insulation problems:

  • 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, has visible signs of mold, and/or is damp all the time.

At GSM Services, we can improve the condition of your crawl space and the living space above with products that are durable, long-lasting, and made especially for the crawl space environment.

Spray Foam Insulation Has Several Advantages

Spray foam insulation in Clover

A versatile energy-saver. 2-part spray foam expands after it's applied, creating an effective thermal and moisture barrier. Thanks to its unique properties, it can be used to solve comfort & energy problems in many parts of the house.

Air barrier: Spray foam air-seals and insulates in one step. Its ability to expand and fill gaps and cracks make it an ideal air-sealing material, and it stays in place because of its super-adhesive qualities. Spray foam is often spot-applied as an air-sealing treatment prior to filling an attic with blow-in insulation. But when applied in more generous amounts, it can eliminate the need for other types of insulation.

Waterproof: Moisture will soak its way through fiberglass and cellulose insulation, but polyurethane spray foam stops it cold. Its closed cell structure means that water can't migrate from one tiny cell or bubble to a neighboring one.

Foolproof: Did you know that a void (missing insulation) of just 5% of an insulated area can diminish overall insulation performance by as much as 50%? It's very difficult to install fiberglass insulation perfectly, so voids are not uncommon. But spray foam's expanding, super-sticky characteristics just about eliminate the possibility of voids. And once the foam cures, it's not going to settle or shift like fiberglass or cellulose can.

Rigid Foam Insulation Panels Outperform Fiberglass in The Crawl Space

Long-lasting. Rigid foam insulation can’t be damaged by moisture and won’t degrade in appearance or R-value over time. In a crawl space, it’s usually installed against the interior face of foundation walls.

Rigid foam insulation performs much better than fiberglass in a crawl space. This type of 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 secured 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 costs more than fiberglass insulation, it’s less expensive when you consider that you’ll never have to clean up or redo a mess of damaged, ineffective installation. Rigid foam will deliver the same performance and benefits in 15 years as it does on day #1.

Installing TerraBlock™ insulation on a crawl space floor

Top performance. Covering the crawl space floor with TerraBlock™ insulation creates a durable thermal and moisture barrier.

TerraBlock™ Insulation is Flexible and Strong for Use on Crawl Space Floors

Does your crawl space need insulation on the floor as well as on the walls? TerraBlock™ insulation has what it takes to handle tough crawl space conditions. It’s made from a special type of rigid foam insulation that is flexible enough to install over rough, irregular crawl space floors. Faced on both sides with durable vinyl, TerraBlock™ insulation has excellent puncture and abrasion resistance.

In addition to providing extra insulation value, TerraBlock™ creates a clean, comfortable floor for homeowners and service pros who need to move around in the crawl space.

Benefits of insulating your crawl space with rigid foam

  • Stable and reliable. 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.
  • Effective 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.
  • Unfriendly to mold. Mold can’t take hold on rigid foam because it contains no organic food source and it doesn’t hold moisture.
  • Better ductwork performance. Ducts located in the crawl space benefit from rigid foam installed against crawl space walls.
