The Role Of Insulation In Mold Growth
In most modern homes, the insulation material of choice is fiberglass. The layers upon layers of tiny mineral fibers are great at trapping air to create a barrier that keeps cold air in and warm air out – or vice versa. But as far as moisture and mold control go, fiberglass leaves something to be desired.
Fiberglass itself is not edible to mold, but in addition to trapping air, mineral fibers are also excellent at trapping moisture and dust. Fiberglass insulation has thus been known to contribute to mildew growth in basements and other vulnerable areas, although the real cause of the problem is the crack or leak that’s allowed moisture to reach the insulation.
Still, depending on the severity of the leak and how likely it is to grow worse, switching your insulation to something less fungus-friendly may be the best solution to your problem. There are several kinds of alternative insulation, and while they may cost more than basic fiberglass, they also offer better results.
- Polyurethane foam is an excellent all-around insulation which is also extremely water-resistant. In fact, it’s FEMA approved to withstand extended contact with floodwater without needing replacement, something which is not true about fiberglass.
- Cellulose insulation has advanced by leaps and bounds in the past few decades, and current products boast improved resistance to both moisture and mold growth as compared to standard fiberglass.
- Plastic sheets filled with air bubbles offer a more machined, industrial approach to wall insulation.
Whatever your preference may be, with the right waterproof materials it’s possible to make insulation a part of the solution instead of a part of the problem.
