Materials Commonly Used For Crawlspace Insulation

1. Fiberglass Insulation

Fiberglass insulation is a popular choice for crawlspace insulation due to its affordability and ease of installation. It consists of small glass fibers that trap air, creating an insulating barrier. Fiberglass insulation is available in rolls or batts that can be easily cut and fitted into the crawlspace.

Pros:

  • Cost-effective option
  • Easy to install
  • Effective at reducing heat transfer

Cons:

  • Can be itchy and irritate the skin during installation
  • May degrade over time and lose its insulation properties
  • Not a good barrier against moisture

2. Spray Foam Insulation

Spray foam insulation is a versatile option for crawlspace insulation. It is applied as a liquid that expands and hardens into a durable foam. Spray foam insulation creates an airtight seal, providing excellent thermal insulation and moisture resistance.

Pros:

  • Superior insulation and air sealing properties
  • Protects against moisture and prevents mold growth
  • Long lifespan

Cons:

  • Higher initial cost compared to other insulation materials
  • Requires professional installation
  • Can emit harmful fumes during installation if not properly ventilated

3. Rigid Foam Insulation

Rigid foam insulation, also known as foam board insulation, is a popular choice for insulating crawlspaces. It is made from polystyrene or polyisocyanurate and comes in rigid panels. Rigid foam insulation provides excellent thermal resistance and moisture barrier, making it an effective option for crawlspaces.

Pros:

  • Strong and durable
  • High thermal resistance
  • Resistant to moisture and mold growth

Cons:

  • More expensive than fiberglass insulation
  • Requires professional installation for best results
  • Not as easy to cut and fit into irregular spaces

Vapor barriers or plastic sheeting are commonly used in crawlspaces to prevent moisture from entering the space. While not a traditional insulation material, vapor barriers play a crucial role in moisture control. They are usually made of polyethylene and are installed on the ground and walls of the crawlspace.

Pros:

  • Effective at preventing moisture infiltration
  • Helps control humidity levels
  • Relatively easy to install

Cons:

  • Does not provide insulation against heat transfer
  • Needs to be properly sealed to be effective
