Questions

Frequently Asked Questions

What Is residential spray foam insulation?

Residential spray foam insulation is a type of insulation applied as a liquid that expands into a foam, creating an air-tight barrier. It is used in walls, attics, crawl spaces, and other areas to improve energy efficiency by reducing air leakage.

How does spray foam insulation work?

Spray foam insulation expands upon application, filling gaps and cracks in building materials. This creates a sealed layer that helps prevent air movement, improving thermal resistance and moisture control.

What are the main types of spray foam insulation?

There are two main types: open-cell and closed-cell spray foam. Open-cell is less dense, offers sound dampening, and is typically used in interior applications. Closed-cell is denser, provides a higher R-value, and adds structural strength and moisture resistance.

Is spray foam insulation safe for homes?

When installed properly by trained professionals, spray foam insulation is safe. It should only be applied with appropriate ventilation and protective equipment during installation, as the chemicals used need time to cure.

How long does spray foam insulation last?

Spray foam insulation can last over 20 years without degrading when properly installed. It doesn’t sag or settle like traditional insulation materials.

What is the R-value of spray foam insulation?

Open-cell spray foam typically has an R-value around 3.5 to 3.7 per inch, while closed-cell spray foam has an R-value of about 6 to 7 per inch. R-value indicates thermal resistance; higher values mean better insulation performance.

Where in the home can spray foam be applied?

Spray foam can be applied in attics, walls, basements, crawl spaces, rim joists, and around windows and doors. It is suitable for both new construction and retrofit projects.

Will spray foam help reduce my energy bills?

Yes, spray foam insulation improves a home’s energy efficiency by reducing air leaks and maintaining indoor temperatures. Homeowners often see noticeable reductions in heating and cooling costs.
