Could Poor Crawl Space Insulation Be
Costing You This Winter?

Winter is just around the corner, and that means it's time to prepare your home for the colder weather. While you're weather-stripping doors and checking windows, don't forget one of the biggest sources of heat loss in your home: the crawl space.
The best way to prepare your house for winter is with proper insulation, starting from the bottom.
Why Your Crawl Space is Costing You Money
Think of your home as a single system. Due to a phenomenon called the "stack effect," cold winter air flows into the uninsulated, vented crawl space at the bottom of your house. This cold air then travels up through your floors and into your living space, making your rooms drafty and your floors frigid. Your heating system is then forced to work overtime just to keep up, resulting in soaring energy bills.
Many homes have old, damp fiberglass insulation hanging from the floor joists. Fiberglass batts act like a sponge, absorbing moisture, which causes them to compress and eventually fall to the ground. This wet insulation also becomes a prime breeding ground for mold and mildew.
Insulate Crawl Space Walls: SilverGlo™ Insulation

To truly keep your crawl space warm, and by extension, your entire house, you need an insulation solution that's built for the damp, below-grade environment.
Frontier Foundation & Crawl Space Repair, the leading installer of crawl space solutions, uses SilverGlo™ rigid foam insulation. This advanced product is designed to provide a permanent, effective thermal barrier.
Here’s what makes SilverGlo™ different:
- Superior R-Value: SilverGlo™ boasts an impressive R-11 rating. It’s an Expanded Polystyrene (EPS) foam board that is infused with graphite, which increases its insulating R-value by 24% over standard white foam board.
- Radiant Barrier: One side features a built-in radiant barrier that reflects heat. In the winter, it reflects heat back into your crawl space, and in the summer, it reflects heat out.
- Waterproof & Mold-Resistant: Unlike fiberglass, SilverGlo™ is a closed-cell, waterproof material. It will not absorb moisture, support mold growth, or lose its insulating power over time.
This powerful crawl space insulation is exclusive to authorized dealers in the Basement Systems international contractor network. By insulating the crawl space walls and air-sealing the rim joist, Frontier Foundation & Crawl Space Repair stops cold air infiltration at the source, helping to lower humidity levels and keep your entire home more comfortable.
Seal & Insulate the Crawl Space Floor
In colder climates, we recommend installing TerraBlock™ foam insulation on the crawl space floor. This specialized flexible insulation is then covered with our CleanSpace® moisture barrier that completes the sealing process. The crawl space is now isolated from outside conditions.
As the U.S. Department of Energy writes, "If you properly insulate your crawl space—in addition to air sealing and controlling moisture, you will save on energy costs and increase your home's comfort."
