Spray foam insulation is a type of insulation that is applied as a spray and expands to fill the spaces it is applied to. It is used to insulate a variety of spaces, including attics, walls, and crawl spaces, and is known for its ability to provide a high level of insulation with a relatively thin layer. Spray city insulation is one of the best firms to call for spray foam insulation.
There are two main types of spray foam insulation: open-cell and closed-cell.
1. Open-cell spray foam
Open-cell spray foam is made up of cells that are not completely closed, which gives it a spongy, flexible texture. It is less dense than closed-cell spray foam and has a lower R-value, which means it is less effective at insulating. However, it is also less expensive and is often used in areas where a higher R-value is not necessary, such as in attics or walls.
