Spray Foam Insulates and Seals Gaps and Crevices

Spray foam  also called insulating foam sealant or expanding foam, is a versatile product that consists of unique liquid components that react to create a foam solution that insulates and fills gaps and crevices as it hardens. It can help limit air leakage throughout a home, which reduces energy usage, limits intrusion of pollutants and allergens, and helps with severe weather resistance.

The spray foam is produced by a chemical reaction between two materials (isocyanates and polyol resin, typically) held in separate hoppers or tanks and transported by gas pressure or liquid until they meet at the tip of a special spray gun. The isocyanates and polyols mix quickly to form a solution that expands up to 30-60 times its liquid volume after it’s sprayed on site, creating an effective insulator and air and moisture barrier.

Spray Foam Unleashed: Elevating Energy Efficiency in Homes and Businesses

Everyone I talked to said the best way to get spray foam to do its job is in a warm climate, and that it’s important to apply it while it’s still hot. If applied when it’s too cold, the foam may not fully adhere and will deteriorate over time.

It’s a good idea to keep a can of spray foam handy for a few quick fixes around the house. One easy trick is to squirt a little expanding foam around a loose showerhead and carve off the excess before it sets, securing the fixture. Spray foam can also firm up other loose and wobbly items, like a loose shower curtain rod.
