While insulation has a very long life expectancy, it is not impervious to damage, and it will have to be replaced at some point. Home improvement experts recommend having the insulation inspected at least once a year to catch potential problems before they lead to leaks or severe energy loss. Below is some information about the type of insulation in your home and signs that something may be wrong with it to help you avoid waiting too long to replace it.

A Guide to Insulation Types

In most homes, insulation is installed in the attic, around the doors and windows, between walls, and under crawl spaces. Generally, home improvement professionals will use one of the following:

• Fiberglass: This brightly colored insulation is commonly used between studs, joists, and beams. It is very common in homes because it is inexpensive, non-flammable, and highly moisture resistant. However, homeowners should not interact with this material as it is comprised of fibers that can irritate your lungs and skin.
• Cellulose: It is an environmentally friendly option comprised of recycled paper and other organic materials. To prevent moisture and pest damage, it is typically sprayed with chemicals, and for the best results, should be replaced every five years. 
• Rock Wool: This mineral wool insulation is similar to fiberglass except that it doesn’t create the same irritating effect, which makes it more expensive. Usually, it is either blown or poured out of bags into the desired area and works well in climates that experience intense summer heat.

What Are Some Signs of Insulation Wear?

As insulation reaches the end of its life span, it compacts under its weight. It could also begin to deteriorate; however, this is typically only an issue for cellulose materials. Mold and mildew can also degrade insulating materials. A roof leak or damage to your siding can lead to moisture accumulation, and this can cause the insulation to compact, settle, and develop air leaks. 

One of the biggest insulation issues for older homes is that it doesn’t meet the recommended R-values of the property. This results in gaps around attic joists. In most instances, it should be between 10 and 16 inches thick, but having a home improvement expert inspect it is the best way to determine if you have enough installed.
