Drafty rooms and rising energy bills are signs that your crawl space is not properly insulated. When the area beneath your home is exposed to outdoor air and moisture, it can make floors colder, reduce energy efficiency, and contribute to mold, humidity, and structural issues over time.
At JES Foundation Repair, we help homeowners create a more comfortable, better-protected home with engineered crawl space solutions like ExTremeBloc™ insulation. This page explains how ExTremeBloc™ works, the benefits it provides, and how our crawl space encapsulation system improves moisture control, energy efficiency, and overall home health.
High R-value insulation panels provide exceptional thermal resistance with radiant heat barrier coating and Class A fire rating for safe, effective temperature control.
The lightweight, yet durable wall panels are made with eco-friendly materials, including a graphite-infused, expanded polystyrene core.
The panels are made with an integrated termiticide and pest deterrent, and the installation process includes leaving maintenance gaps for inspections.
Crawl space insulation controls moisture and prevents mold growth, significantly improving indoor air quality throughout your home while reducing allergens and musty odors.

Proper insulation creates an inhospitable environment for pests seeking damp spaces, deterring infestations while maintaining dry conditions that protect your home’s structural components from water damage.

Insulated crawl spaces maintain consistent floor temperatures, eliminate cold spots, and reduce heating and cooling costs, delivering long-term energy savings and comfort throughout your home.
