Insulating a Basement in a Condo in Hatfield, MA

This condo owner called us hoping that we would be able to help him. His condo association was looking into different insulation specialists due to an issue they had, and we had been referred from a friend. They were interested in replacing the insulation in their shared basement. They had fiberglass insulation, which was falling down, and they were having issues with mold in this basement as well. The fiberglass needed to be removed, the mold needed to be remediated, and then the condo association wanted new insulation put up.

We were able to insulate this basement using two separate solutions. These solutions combined gave them a very insulated condo complex, but also, they had the benefit of sound dampening as well. Our first solution was using two part spray foam in the rim joist. (The rim joist is the perimeter of the floor framing system along the exterior of the house.) This spray foam expands and fills all cracks and gaps in the rim joist and over the sill plate. Then, we installed RockWool batts on the ceiling of the basement. RockWool is amazing -- made of volcanic rock, it is fire resistant and sound dampening. The condo owners will no longer have an issue with hearing their neighbors in the basement, and they will be much more comfortable in their homes!
