Why Spray Foam Is the Best-Suited Product for Crawl Space Insulation

Many homeowners are looking for ways to improve the energy efficiency and comfort of their homes. Despite today’s high cost of living, the search for a suitable solution continues. Because they can lead to issues like cold floors, drafts along baseboards, frozen pipes, and higher energy bills, vented crawl spaces can reduce your home’s energy efficiency and comfort.

Crawl space vents allow in winter’s cold air and summer’s humidity, both of which can mean less comfort and increased energy consumption. Although many homeowners agree that sealing and insulating the crawl space is the best solution, a majority don’t know what proper crawl space insulation involves. Here’s a look at spray foam and why it’s the best-suited product for crawl space insulation.

Spray foam is the best and most effective product for crawl space insulation because it offers the following benefits:

Airtight Seal

Air leaks are one of the biggest contributors to high energy bills, second only to insufficient insulation. As such, you’ll want to seal the air gaps in your crawl space thoroughly. Spray foam is uniquely capable of sealing every hole and crack. Compared to the other insulators, spray foam provides a more powerful insulation, one that’s 24 times less pervious to air infiltration. This means that aside from improving your home’s energy efficiency and helping you save money, spray foam insulation keeps unfiltered air from circulating, thereby increasing your indoor air quality.

Moisture Barrier

In addition to air, exposed holes and cracks can let moisture into your crawl space as well. In fact, 90 percent of the moisture in our homes is airborne. Unlike the other insulation materials, spray foam insulation is impervious to water. Because this insulator does not absorb water, it offers protection from airborne moisture and leaks. Since spray foam insulation prevents moisture accumulation or permeation, it’s the best choice for those who live in areas prone to flooding.

Deters Microbial Growth

The cleanliness of your crawl space has a significant impact on your indoor air quality. Spray foam insulation discourages the growth of mold or bacteria. The inert polymer it’s made from offers no source of food for these organisms. As such, spray foam insulation provides better protection against microbial growth. Mold and mildew can diminish your indoor air quality and impair the structural success of your home.

Longevity

Unlike other insulation materials, spray foam has an indefinite lifespan and is known to provide optimal performance for extended periods. You can, therefore, enjoy the benefits offered for years on end before the need to re-insulate arises.

High Per-Inch R-Rating

Compared to other insulation materials, spray foam has the highest R-value on the market. Spray foam expands as it cures, creating an airtight seal against incoming air. Once cured, it will help prevent heat transfer by filling in every nook and cranny. Because of its insulating properties, spray foam insulation offers superior energy savings. Spray foam gives a 50 percent cost savings rate where most of the other insulation materials provide an average of 30 percent.

Environmentally Friendly

Other than cost, the most inquired for bit of information about spray foam insulation concern its overall impact on the environment. Compared to other insulators like fiberglass and cellulose,

  • Spray foam is the most eco-friend insulation material for a number of reasons.
  • Spray foam helps create a green household by reducing energy consumption.
  • Spray foam insulation offers adequate protection against moisture and microbial growth.
  • This insulator is designed to provide optimal performance and last indefinitely, leading to the production of fewer consumed materials.

Spray foam insulation comes with the following benefits:

  • High per-inch R-rating
  • Faster, less messy installation
  • Waterproof
  • Resistant to humidity
  • Provides a vapor barrier
  • No microbial growth
  • Installation around obstacles and utilities
  • Expands, filling gaps and voids
