In our last blog post, we looked at the various insulation types that are available to homeowners. We also looked at a few of their pros and cons, and offered some insight as to why we prefer working with Owens Corning’s AttiCat® blown-in insulation. This week, we would like to look at insulation types as they stand up to one of the biggest environmental factors in the south eastern states: humidity.
Humidity by Region
The insulation used to protect homes from heat, cold, and humidity is extremely important, especially when it comes to the type of home insulation being used. There are many types of insulation available, all suited for various regions and climates. Here in the Florence and Muscle Shoals area of Alabama, blown-in insulation performs most efficiently for two reasons: its mold resistance and its long-lasting R-value.
The Types of Insulation: A Recap
There are many different types of insulation available for a home. You can find blankets or rolls of fiberglass, rockwool, and cotton insulation that are cut to fit the spaces being insulated. Structural insulated panels (SIPs) can be used to insulate an entire wall or surface (such as the attic or crawl space) in 4×8 sheets or 8×24 sheets, with the larger pieces typically being used during new home construction due to their size. Another type of insulation (more toxic and reputed to combust spontaneously) is spray foam, which is sprayed on as a liquid, allowing it to fill cracks and crevices. Loose-fill or blown-in home insulation consists of small particles of fiberglass insulation blown in to enclosed spaces, like your attic, with a special machine.
What Impacts the Efficiency of Insulation
External factors like heat and humidity can have an impact on the efficiency of your home’s insulation. Specifically, properties that are located in southern states require home insulation that can stand up to intense humidity, rather than simply blocking out cold air.
Humidity can be countered in many areas by dehumidifiers or air conditioning systems. Unfortunately, there is little control over sealed areas such as the attic – or between the ceiling and the roof. Mold is a huge problem that can develop in homes that are well-sealed. All it needs is humidity or moisture, and something to feed off. Although many types of insulation (especially fiberglass) is resistant to mold formation, the surrounding materials may be. Fortunately, AttiCat®’s blown in insulation is easy to work around, in the event that a mold problem develops and needs treatment.
