Are you struggling with damp, moldy, or insufficiently insulated crawl spaces? Tar Heel Basement Systems has the answer to your concerns. As industry leaders, we understand the important role that a well-maintained crawl space plays in the overall health and safety of your home.
That’s why we are proud to present ExTremeBloc™, a high-quality crawl space insulation solution that ensures your home remains dry, healthy, and energy-efficient. Let’s explore how ExTremeBloc™ stands out in the market, its unique benefits, and why it’s the go-to choice for homeowners across North Carolina.
ExTremeBloc™: Rethinking Crawl Space Insulation
The performance of your crawl space insulation is crucial in maintaining your home’s health and comfort. Inadequate or poorly installed insulation can lead to issues such as moisture accumulation, mold, pest infestations, and excessive energy usage. Enter ExTremeBloc™ Crawl Space Insulation. This revolutionary product, exclusive to Tar Heel Basement Systems, goes beyond traditional insulation methods to offer optimal protection and energy efficiency.
ExTremeBloc™ combines graphite-impregnated insulation with an expanded polystyrene core and a radiant heat barrier surface. With this, your crawl space walls get a consistent R-value of 10, significantly enhancing the performance of your home’s insulation system.
Why ExTremeBloc™?



At Tar Heel Basement Systems, we’re committed to providing our customers with the highest quality solutions. ExTremeBloc™ Crawl Space Insulation reflects this commitment. Its distinguishing feature is the infusion of tiny graphite particles into its foam insulation. These particles reflect heat and lower the material’s conductivity, enhancing its R-value per inch.
Additionally, ExTremeBloc™ boasts a radiant barrier that reflects heat back into your crawl space, optimizing energy savings. It also resists moisture penetration, thereby reducing the risk of mold, pests, and decay in your crawl space.
