Prevent mold, moisture, and comfort problems with the right insulation
damaged fiberglass insulation

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

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

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.

Crawl space vents bring humid air into a home during the summertime, where it’s cooled in the crawl space. As this air cools, the relative humidity of the air rises, and the excess moisture is left on surfaces in the crawl space in the form of condensation.

Some of this moisture ends up on the fiberglass insulation in your crawl space. Wet or damp fiberglass insulation does not insulate as well as dry insulation, and the added weight will pull it from the ceiling, leaving it in messy, useless piles on the floor. Wet insulation can actually become a food source for mold and rot–which will also grow on any other organic material in your crawl space–including your wood framing.

Additionally, while you’re insulating your floor, you probably have utilities in your crawl space, such as your water heater, furnace, heating ducts, and hot water pipes. If you allow the cold winter air into your home through crawl space vents, these heat-generating utilities will be forced to work that much harder.

When you count on Tar Heel Basement Systems 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.

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!

installing ExTremeBloc insulation

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