Wool insulation: an interesting alternative to more commonly used fiberglass and cellulose insulation. Benefits: When installing fiberglass insulation, skin irritation and lung damage are potential problems if not using the appropriate clothing and masks. With wool, that is not a problem because it is a natural product. Other benefits include: No off-gassing emitted into the air, better moisture and temperature control, mold resistant, fire-resistant, and climate control. Ultimately, wool insulation seems like an investment in a home that will see long-term benefits. Check out this American Wool website to learn more!
