DIY kits exist for small projects, but whole-home installs need trained professionals for safety and building code compliance.
Attics, walls, crawl spaces, basements, metal buildings, barns, and new construction homes. Versatile, durable, and energy-saving.
People often want to know how spray foam stacks up against fiberglass and cellulose. Key comparisons include:
R-Value: Spray foam has a higher R-value per inch than traditional insulation, especially closed-cell foam.
Air Sealing: Spray foam creates a superior air seal, filling every crack and crevice to prevent air leaks and drafts. Fiberglass and cellulose batts do not provide an air seal.
Moisture Resistance: Closed-cell spray foam is a moisture barrier, while fiberglass and cellulose can absorb water, leading to mold and a loss of effectiveness.
Pests: Spray foam provides no food source for rodents or insects, making it more pest-resistant than other materials.
Cost: Spray foam has a higher initial cost but a better long-term return on investment due to energy savings.
A key benefit of spray foam is its longevity. When installed correctly, it is a durable, permanent solution that can last for the entire lifespan of a home.
The two main types are Open-cell and Closed-cell spray foam.
Open-cell spray foam is less dense, more flexible, and more affordable, making it excellent for filling large or irregularly shaped cavities. It's a great air barrier and also offers sound-dampening properties. However, it's not a vapor barrier and can absorb water.
Closed-cell spray foam is much denser and more rigid. It has a higher R-value per inch, adds 33% structural strength to walls, and is a class 2 vapor and moisture barrier. It is more expensive than open-cell but is a better choice for areas where moisture control is critical, such as basements, crawl spaces, or exterior applications.
Yes. Spray foam insulates and air-seals in one step. Many homeowners cut heating and cooling bills by up to 30-75%.
