Basement insulation levels continue to increase as wall R-value requirements become more stringent. Installing continuous stone wool insulation adjacent to the foundation wall greatly improves the thermal performance of the basement.

ROCKWOOL COMFORTBOARD™ insulation will maintain consistent thermal resistance, even when exposed to moisture-an important consideration for exposed below- grade insulation.

When exposed to ground moisture, COMFORTBOARD™ will resist water absorption, reducing the risk of moisture penetrating the below-grade waterproofing.

Bulk water that contacts the outer surface of the stone wool will largely drain away and not be absorbed into the insulation. In this way, the insulation acts similar to a drain composite, effectively acting as a cavity break. Furthermore, as stone wool is inorganic,

COMFORTBOARD™ will not rot, corrode, or support mold and fungal growth when wetted. This greatly improves the durability of the basement wall assembly.
