Insulate It Solutions – Is Spray Foam Insulation Safe?

spray foam insulation is a popular product that can help reduce energy bills in homes by providing an air seal, as well as sealing small gaps and tight areas where home framing meets. But it’s not the safest insulative material for homes, and the negative effects might outweigh the positives.

  • Comparing Spray Foam Insulation to Traditional Methods

The spray foam material is made of two liquid chemicals that undergo a chemical reaction to create the insulation as they spread. The chemicals, called the A and B sides, off-gas volatile organic compounds (VOCs) when the spray foam expands. The chemicals are also abrasive to the skin and respiratory system. As a result, spray foam requires special safety equipment and procedures to apply.

Homeowners can choose between open- and closed-cell spray foam insulation. Closed-cell foam costs more, but it’s physically stronger and provides a better vapor barrier than open-cell foam. It also has higher R-values. Homeowners can also choose low-GWP blowing agents, such as HFOs, which may increase the installation cost by 10 to 15 percent, but might lead to higher energy savings at the same time.

Spray foam can be installed in basement rim joists, crawl spaces, attics, overhangs and knee walls. It can also be applied in new construction and retrofits, such as replacing old cellulose or fiberglass insulation. Homeowners can purchase spray foam kits to install the insulation themselves, but it’s best to hire a professional for larger projects and areas that require precise insulation performance.
