How Often Should Attic Insulation Be Replaced?
There are many factors that contribute to the need for attic insulation replacement. A few of these factors are:
-The age of the insulation
-Moisture in the attic, possibly caused by a roof leak
-Mold or mildew in the attic or on the insulation itself
-Contamination within the insulation (dirt, dust, animal droppings, insects, etc.)
-The R-Value (insulation value) of the insulation material
Depending on the insulation material used, attic insulation tends to lose it's R-Value over time. Generally speaking, fiberglass insulation, if it is not damaged, is good for about 15-20 years. This is only if it does not get damaged by water, fire, mold, mildew, or rodents. For cellulose insulation, which is what Olympic Restoration Systems recommends, insulation needs to be replaced after about 30 years if undamaged. The added benefit of our cellulose insulation is that it is treated with a non-toxic borate solution that gives it a Class-1 fire safety rating, and makes it pest and insect repellant. Cellulose insulation also has a higher R-value than fiberglass insulation.
The best way to know if your attic insulation needs to be replaced is to have it inspected by an attic insulation specialist.
