attic insulation is one of the most powerful home energy-saving solutions available. Unlike fiberglass batts, it is sprayed directly onto the surface of walls, attics and rim joists. Once sprayed, it expands to fill in any cracks and crevices. This gives it an excellent coverage rate, which is often higher than other types of insulation. It also creates an effective vapor barrier, so homeowners don’t need to worry about applying a separate vapor retarder.

Debunking Common Myths About Spray Foam Insulation

Its air sealing properties make it very useful in new construction, as well as in existing homes. Its power to restrict air flow helps prevent the escape of conditioned air during the heating and cooling cycle, which is a major source of energy loss in most homes. It can also help prevent condensation in wall cavities, which is caused when there’s a difference between the inside and outside temperature.

Another advantage of spray foam insulation is its ability to reduce noise. It effectively dampens sound waves, which makes it a great choice for those who live in urban areas or busy neighborhoods. However, it’s important to note that it will not stop sounds from traveling between rooms or from outside.

Lastly, spray foam insulation is an excellent deterrent for rodents. These pesky critters can cause significant damage, especially in homes with minimal or no insulation. The seal created by the spray can keep them out of attics, basements, spare bedrooms, cardboard boxes and inside furniture.
