At Lewis Insulation, we specialize in closed cell spray foam insulation in St Paul and the surrounding areas. We are often asked the same questions about this type of insulation, so we thought we would take some time to address the ones we hear the most often.
Q: Why should I consider spray foam insulation for my home?
A: There are plenty of reasons you should consider spray foam insulation the next time you need to upgrade your home’s insulation. It is a cost-effective way to insulate your home, and you will notice a decrease in your heating and cooling bills. Plus, it is an excellent way to reduce outside noise pollution. It will not allow moisture through either.
Q: What are the differences between closed cell spray foam insulation and open cell spray foam insulation?
A: The biggest differences between closed cell spray foam insulation and open cell spray foam insulation are that closed cell has a higher R-value than open cell. Plus closed cell is virtually impermeable to air, and open cell allows more air and vapor into your home.
Q: Will spray foam insulation help with the structural integrity of my home?
A: Closed cell spray foam insulation is the only type of insulation material that can add structural integrity to your home. The National Association of Home Builders Research Center did some testing and found that spray-applied polyurethane foam insulation increased rack and shear strength two to three times. They compared spray foam insulation between wood and steel stud wall panels with glass fiber insulation with standard stick-built components.
Q: Will spray foam insulation help keep mold from growing in my home?
A: Yes. Among its many other benefits, closed cell spray foam insulation will help with mold growth. Mold needs moisture, a food source and warm temperatures to grow and thrive. Spray foam insulation cannot be eaten by mold because it has no nutritional value, and using this type of insulation will help to eliminate condensation. That means harmful moisture cannot build up in your attic or other crawl spaces. Spray foam insulation also eliminates air movement within the wall cavity itself, so that all means there is less of a chance of mold becoming a problem.
