Stop Losing Up to 15% of Your Home’s Heat Through the Crawl Space

A poorly insulated crawl space can account for as much as 15% of total heat loss in your home. Installing reflective bubble insulation under or between floor joists helps reflect radiant heat back into your living space, improving comfort and reducing energy waste. This simple upgrade can lower utility costs and extend the life of your HVAC system by reducing the strain on heating and cooling equipment.

An Under-Insulated Crawl Space Can Drain Your Wallet!

During the cold winter months, warm indoor air can escape through your crawl space, forcing your HVAC system to work harder to maintain comfortable temperatures. In the summer, hot, humid air can seep inside, making your air conditioner run overtime. No matter the season, radiant heat easily transfers through an uninsulated crawl space—raising energy costs and reducing comfort.

Installing our ESĀ® reflective bubble insulation helps block heat transfer, protect against moisture, and prevent mold growth, keeping your home efficient and comfortable year-round.

Installing ESĀ® Foam (Foil/Foil) Reflective Insulation in your crawl space provides far more than basic insulation—it’s an upgrade to your home’s overall efficiency and protection. By reflecting radiant heat, it minimizes heat transfer through one of the most energy-inefficient areas of the house, helping your home stay warmer in winter and cooler in summer.

The insulation also functions as a vapor barrier, shielding your crawl space from excess moisture that can lead to mold growth, wood rot, and structural damage. This added layer of protection helps preserve your home’s foundation and supports healthier indoor air quality by reducing allergens and airborne irritants.

Built with a durable, tear-resistant design, ESĀ® Foam Reflective Insulation delivers long-term performance, ensuring your home remains comfortable, efficient, and protected year after year—a smart investment in both energy savings and home health.

Why Insulate Crawl Spaces with Radiant Barriers & Reflective Insulation?

Crawl spaces are especially prone to temperature fluctuations and moisture buildup, both of which can impact your home’s energy efficiency and indoor air quality. ESĀ® Double Bubble (Foil/Foil) and ESĀ® Foam Reflective Insulation provides dual-layer protection that reflects radiant heat and resists moisture intrusion. It helps retain warmth during winter and blocks unwanted heat during summer, leading to lower energy costs and a more comfortable home year-round.

The insulation’s moisture-resistant properties also help prevent mold growth and structural damage—making it an excellent solution for damp or humid environments.

Key Benefits:
  • Reduces drafts and heat loss for improved energy efficiency
  • Blocks moisture to prevent mold, mildew, and wood rot
  • Ideal for both new construction and retrofit applications in damp crawl spaces

Radiant Barriers, Reflective Insulation, and a Healthier Home

Your home’s health begins in the crawl space. When left uninsulated or exposed to moisture, crawl spaces can trap humidity and become ideal environments for mold, mildew, and pests—issues that can damage your home’s structure and affect indoor air quality.

Installing ESĀ® Double Bubble (Foil/Foil) and ESĀ® Foam Reflective Insulation adds more than just energy efficiency—it provides a vital layer of protection against moisture infiltration. By keeping your crawl space dry, it helps prevent mold growth and reduces allergens that can lead to respiratory problems.

This radiant barrier also safeguards your foundation and wooden structures from long-term moisture damage, helping preserve your home’s integrity and value. Insulating your crawl space with a radiant barrier is one of the most effective ways to maintain a healthy, comfortable, and energy-efficient home.
