Prevents mold & mildew
Keeps moisture out of your crawl space and creates a vapor barrier when seams are taped.
Reflects radiant heat
Reflective insulation redirects heat back into your home, making your floors warmer in winter.
Increases HVAC efficiency
Saves money year-round by preventing heat gain/loss
A poorly insulated crawl space could cost you a fortune.
In cold winter months, warm indoor air can easily escape into your crawl space, forcing your HVAC system work extra hard to regulate your indoor temperature. In warmer months, air that is damp and warm can seep into your home, causing your air conditioning to work harder. Regardless of the outdoor temperature, radiant heat can easily flow through your crawl space in both directions. By installing reflective bubble insulation, you can fix these problems and ensure your home is safe from moisture and mold.
15% of heat loss can be attributed to a poorly insulated crawl space
When you install reflective bubble insulation under or between floor joists, it will reflect radiant heat back into your home. This can save you a great deal on energy bills and prolong the life of your HVAC system.

Prevents moisture from entering your crawl space.
When placed on the floor of your crawl space, reflective insulation can work as a vapor barrier—ensuring that moisture from the ground doesn't seep in and lead to issues like mold, mildew, odors, and other moisture-related problems. In order to maintain a vapor barrier, make sure to tape the seams with reflective insulation tape.

More About Crawl Space Insulation
Crawl space insulation in your home is more important than you may think. 15% or more of a home's total heat loss can be attributed to an improperly insulated or un-insulated crawl space. Reflective insulation is an excellent product to use for insulating a crawl space. It is strong, light weight and very clean to install, unlike fiberglass insulation. EcoFoil Bubble Insulation provides a moisture vapor barrier (when seams are taped), controls temperature and prevents cool, damp air from invading the floor above. Rolls of reflective insulation are made to fit between empty floor joists or stapled right across the bottom for unfinished applications.
When installed in a crawl space, or between floor joists, EcoFoil reflective insulation keeps your home's floors warmer in your living area above while regulating temperatures below as well.
