Spray foam insulation is a great way to keep your home cooler in the summer and warmer in the winter, as well as save on energy costs. In fact, it’s so effective that the cost is often recouped in less than a year. However, the type of insulation you choose will make a difference in how effective your home is, so it’s important to understand what your options are.
Common Misconceptions About Spray Foam Attic Insulation Addressed
The most popular form of attic insulation is fiberglass batting, also known as blanket or batt insulation. It consists of thin fibers of glass and has an R-value of 2.9 to 3.7 per inch. It is easy to install and moisture-resistant when a vapor barrier is used in conjunction with it. However, it is susceptible to mold and fungus, which can compromise its performance. Additionally, it is the favorite snack of raccoons, and may require more frequent replacement than other insulation types.
Another option is blown-in loose cellulose or fiberglass, which is better for filling the nooks and crannies of attics. It has an R-value of 3.7 to 4.3 per inch, and can be installed quickly and easily. It is a good choice for attics with standard joist spacing but requires a vapor barrier to function properly. It can also be prone to mold and fungus but is more resistant to fire than fiberglass. It is also heavier than fiberglass, and not as suited to cold climates.
