Mineral wool typically doesn’t require a vapor barrier. Its high-density level allows it to absorb moisture before it has a chance to penetrate the interior walls of the foundation.

Will mice nest in rockwool?

In this study, house mice caused significant (P < 0.01) increases in the thermal conductance of 10.2-cm thick wall panels, insulated with cellotex, fiberglass, rockwool, styrofoam, and vermiculite. Mouse populations increased 3-to 4-fold inside the insulated panels during the 6-month study period.

Is mineral wool better than fiberglass insulation?

In many ways, mineral wool is a superior insulation product. It has a higher R-value per inch compared to fiberglass, about a 22-37% higher R-value. It contains 70% recycled material, making it a greener product than fiberglass at 20-30% recycled material..

Does wool insulation mold?

The cumulative effect of wool insulation and less relative humidity makes for a tough place for mold to grow.
