Crawl Space Insulation
Improve Comfort. Reduce Energy Costs. Control Moisture.
Energy Shield USA manufactures high-performance crawl space insulation designed to reduce heat loss, control moisture, and improve overall home energy efficiency. Our reflective insulation and foam systems are engineered for installation under floors or between joists, helping reflect heat back into your living space during winter and deflect heat in summer.
Crawl space insulation reduces heat loss, controls moisture, and improves energy efficiency. Energy Shield ES® Double Bubble and ES® Foam reflect heat back into your home in winter and deflect it in summer.
Reflect Heat Back Into Your Home
Insulated crawl spaces reflect radiant heat back into your home during colder months, reducing energy loss and lowering utility costs.
Prevent Moisture & Frost
Insulating a crawl space also provides a vapor barrier, preventing moisture buildup, frost, and condensation that can damage structural components.
Boost HVAC Performance
Proper crawl space installation reduces heat gain in summer and heat loss in winter, helping your HVAC system operate efficiently and extending its lifespan.
Crawl Space Radiant Barrier: Maximize Energy Efficiency
Installing a radiant barrier in your crawl space reflects heat back into your home in winter and deflects it in summer, reducing energy loss year-round. Unlike traditional insulation, a radiant barrier specifically blocks radiant heat, a major source of energy loss through floors and joists.
- Reduce Heating and Cooling Costs – Radiant barriers can lower energy bills by up to 15%.
- Protect Against Moisture and Condensation – Many radiant barriers include a vapor barrier to prevent frost, mold, and structural damage.
- Improve HVAC Performance – Less heat gain in summer and heat loss in winter reduces strain on your heating and cooling system. For even better efficiency, pair your crawl space insulation with ductwork insulation to minimize energy loss through your HVAC ducts.
- Complement Existing Insulation – Works alongside foam or reflective insulation for full thermal protection.

Why Proper Crawl Space Insulation Matters
Crawl spaces are one of the most common sources of heat loss in homes. Without proper insulation, warm air escapes through flooring systems and cold air enters from below.
In homes with basements, similar moisture and heat loss issues occur in below-grade spaces, where basement insulation helps improve comfort, control moisture, and increase energy efficiency.
Common Problems Without Insulation
- High energy costs
- Excessive heat in summer
- Heat loss in winter
- Condensation on joists and flooring
- Moisture damage
Energy Shield reflective bubble and foam insulation create a continuous thermal barrier, improving comfort, reducing energy costs, and protecting your home structure.
For complete building envelope efficiency, crawl space insulation should work alongside reflective house wrap insulation to help control heat transfer through exterior walls and improve overall system performance.

Crawl Space Insulation FAQs
Should crawl spaces be insulated?
Yes. Proper crawl space insulation reduces heat loss, controls moisture, and improves overall energy efficiency, protecting structural components and supporting HVAC performance.
What is the best insulation for crawl spaces?
Reflective insulation, foam insulation, and vapor barriers are commonly used. Energy Shield’s ES® Double Bubble and ES® Foam reflective insulation provide both thermal protection and moisture resistance.
Does crawl space insulation reduce energy bills?
Yes. Proper insulation can prevent up to 15% of heat loss through the crawl space, lowering heating and cooling costs and keeping energy bills under control year-round.far away, behind the word mountains, far from the countries Vokalia and Consonantia, there live the blind texts. Separated they live in Bookmarksgrove right at the coast of the Semantics, a large language ocean.
How does reflective insulation work in a crawl space?
Reflective insulation uses foil surfaces to block radiant heat. In winter, it reflects heat back into your home, and in summer, it deflects heat away, minimizing energy loss and maintaining consistent indoor temperatures.
Can crawl space insulation prevent mold and moisture damage?
Yes. Acting as a vapor barrier, Energy Shield reflective insulation prevents frost, condensation, and moisture buildup, protecting your foundation, joists, and subfloor from mold, mildew, and wood rot.
Can I install crawl space insulation myself, or should I hire a professional?
Both options are possible. DIY installation is feasible for experienced homeowners using lightweight, flexible insulation like ES® Double Bubble. For larger or irregular crawl spaces, professional installation ensures full coverage, maximum efficiency, and proper moisture protection.
Does crawl space insulation improve HVAC efficiency?
Absolutely. Insulated crawl spaces reduce heat gain in summer and heat loss in winter, lowering the workload on your heating and cooling systems and helping HVAC equipment operate more efficiently.
How much energy can I save with crawl space insulation?
Depending on your home and climate, installing crawl space insulation can reduce heating and cooling costs by 10–15% while improving comfort and prolonging the life of your HVAC system.
