Schedule Free Inspection

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.

When you count on BQ Basements & Concrete for your crawl space insulation needs, we will send out an expert technician to inspect your crawl space and recommend the right services. We have the tools and experience to seal air leaks and install high-performance insulation to help improve your home’s comfort and energy efficiency.

Fiberglass insulation in a crawl space tends to soak up moisture and humidity, growing mold and eventually causing it to “drip” off the ceiling.

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!

AquaStop Terra Matting™  crawl space insulation was developed to meet the challenge of insulating rough, uneven crawl space 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 AquaStop Terra Matting™, you get insulation and moisture protection from a single product. When installed over a crawl space floor, AquaStop Terra Matting™ also provides a cushioned surface that service professionals and homeowners will appreciate when moving around in the crawl space.

Terra Matting™ Specifications

  • Padded, Insulated Design: AquaStop 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: AquaStop TerraMatting™ is available in rolls and fan-fold sheets, providing installers with different installation options to suit varying crawl space conditions. AquaStop TerraMatting™ is appropriate for crawl space walls and floors. Compatible With Our CrawlSeal™ System — AquaStop TerraMatting™ can be used as a standalone product, or it can be combined with our CrawlSeal™ Vapor Barrier, AquaStop™ drainage matting, BasementGutter™ French Drains and other products.

AquaStop ExTremeBloc™ 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, AquaStop ExTremeBloc™ boasts a radiant barrier, which reflects heat back into your crawl space for ultimate energy savings. AquaStop ExTremeBloc™ 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 AquaStop ExTremeBloc™ and AquaStop Terra Matting™ together. This keeps the cold out of your crawl space — and the heat in!

AquaStop ExTremeBloc™ Specifications

  • Thick Material: 2″-thick insulation with a radiant barrier to both insulate and reflect heat back into the crawl space.
  • Extra Insulation: AquaStop ExTremeBloc™ has an R-11 value insulation to keep more heat in the crawl space and home.
