Crawl space insulation is important. A number of comfort and energy problems are caused by inadequate or incorrect crawl space insulation.

Any crawl space can be wet and damp, so the insulation must hold up in those conditions. We recommend installing a vapor barrier along with proper insulation to prevent mold and moisture problems and keep your home comfortable year-round.

Our options for crawl space insulation

The crawl space insulation materials that we install are compatible with our crawl space encapsulation and drainage systems to ensure a dry, healthy, comfortable crawl space!

Our crawl space insulation was developed to meet the challenge of insulating rough, uneven floors. However, this innovative insulation is versatile enough to be used on foundation walls as well. The ¾-in.-thick sheet material is covered on both sides with a durable moisture barrier that makes the insulation resistant to puncture and abrasion damage.

When you install our thermal insulation, you get insulation and moisture protection from a single product. When installed over a crawl space floor, our insulation also provides a cushioned surface that service professionals and homeowners will appreciate when moving around in the crawl space.

Thermal floor insulation specifications

  • Padded, Insulated Design -- This floor insulation is made of ¾" of foam insulation. It's padded, puncture-resistant, and durable enough for access by servicemen and homeowners.
  • Installs On Walls & Floors-- Our floor insulation is available in rolls and fan-fold sheets, providing installers with different installation options to suit varying crawl space conditions. Our thermal insulation is appropriate for crawl space walls and floors.
  • Compatible With Our Crawl Space Encapsulation -- Our insulation can be used as a standalone product, or it can be combined with our vapor barriers, drainage matting, drain systems and other products.

VaporLoc Elite insulation panel

Panel power. Thanks to special features that other rigid foam panels lack, our wall insulation provides excellent performance and value when used to insulate crawl space and basement walls.

Crawl Space wall insulation panels look different because they ARE different. Tiny graphite particles permeate its foam insulation to give it that silver/gray shine.

These tiny particles reflect heat and lower the material's conductivity for superior R-value per inch.

In addition to resisting heat conduction, our wall insulation boasts a radiant barrier, which reflects heat back into your crawl space for ultimate energy savings. Our thermal crawl space insulation can also be installed on the perimeter of your floor framing system (rim joist) for maximum energy savings.

For the best in energy efficiency, combine our wall and floor insulation together. This keeps the cold out of your crawl space -- and the heat in!

Wall insulation specifications

  • Thick Material -- 2.3"-thick insulation with a radiant barrier to both insulate and reflect heat back into the crawl space.
  • Extra Insulation--  Our wall insulation has an R-15.3 value to keep more heat in the crawl space and home.
