Crawl Space Insulation

Insulation that is applied between the floor joists just above the ground.

Purpose

Crawl space insulation helps maintain a stable temperature within the crawl space, reducing energy loss and preventing moisture buildup. It contributes to overall energy efficiency and protects against mold and mildew growth.

Examples of Use

1. Installing fiberglass batt insulation between floor joists in a crawl space to improve home energy efficiency.
2. Using spray foam insulation in a crawl space to create a moisture barrier and enhance insulation performance.
3. Applying rigid foam board insulation on the crawl space walls to prevent heat loss and improve the comfort of the living space above.

Related Terms

• Vapor Barrier: A material used to prevent moisture from penetrating insulation and other building components.
• Attic Insulation: Insulation installed in the attic to reduce heat loss or gain and improve energy efficiency.
• Foundation Insulation: Insulation applied to the exterior or interior of a building’s foundation to prevent heat transfer.

Notes

Proper installation of crawl space insulation is critical for achieving optimal performance. It should be combined with moisture control measures to prevent issues like mold growth and structural damage.
