Spray foam is a type of insulation that comes in a liquid form and expands when it’s sprayed, creating a customized airtight seal. It can be applied to attics, crawl spaces, and rim joists in existing homes, as well as new construction and pole barns.
Insulation Contractor tight seal slows down the transfer of heat from the colder outside to the warmer inside, as well as blocking the movement of air through walls and windows. It also helps to prevent moisture buildup and condensation, which can be a problem in wall cavities without adequate insulation coverage.
However, there are a few concerns when using spray foam insulation that homeowners need to be aware of. These include the potential for toxic off-gassing and a lack of airtightness that can lead to mold development and lower indoor air quality.
