When it comes to insulation, spray foam is the clear choice. With it, you can say goodbye to chilly drafts and uncomfortable heat—no matter the season. The benefits of spray foam insulation far outweigh the initial costs, making it one of the smartest investments you can make for your home. Ready to learn why we wholeheartedly recommend it?

Understanding R-Value for Insulation

The R-value is a crucial metric for insulation, indicating its ability to resist heat flow. The higher the R-value, the better the insulation performs. Essentially, the “R” stands for resistance to heat, and a well-insulated home boasts a high R-value.

Surprisingly, the U.S. Department of Energy reports that only 20% of homes built before 1980 have adequate insulation. If you’re among those homeowners, it might be time to consider upgrading or replacing your insulation altogether.

Why Choose Spray Foam Insulation?

Spray foam insulation offers many advantages over traditional materials like fiberglass or cellulose. Here’s why it’s the best choice:

  • Long-lasting: Spray foam can last a century or more!
  • Durable: Built to withstand the test of time.
  • Airtight: Forms a perfect seal that minimizes airflow.
  • Moisture-resistant and mold-proof: Helps protect your home from moisture damage.
  • Structural support: It won’t shift and can help stabilize your home’s framework.
  • Best R-value per inch: Maximizes thermal performance.
  • Customizable: Can be tailored to fit any shape or size.
  • Rodent deterrent: Keeps pests out.
  • Quick installation: Best left to professionals, as it’s not a DIY project for beginners.

Exploring the Two Types of Spray Foam

There are two main types of spray foam: closed-cell and open-cell.

  • Open-cell spray foam consists of cells that are not entirely encapsulated, making it softer and more flexible.
  • On the other hand, closed-cell spray foam has tightly packed cells that keep air and moisture out, making it denser and more rigid. This foam expands significantly—up to 60 times its liquid volume—creating a powerful barrier.

Closed-cell foam is ideal for areas like:

  • Floor assemblies
  • Walls
  • Attics
  • Under radiant heat slabs
  • Foundation walls
  • Interior walls
  • Hot roofs
  • Ice houses
  • Insulated trailers
