This customer from new Hyde Park requested a free in home evaluation. Upon arrival she expressed to our comfort specialist that she felt the temperature of the home was too cold. The rim joist of this home was not insulated. A rim joist is the part of the house where the floor framing rests on the foundation.This is a main source of air leakage and energy loss.We eliminate this problem by sealing & insulating the rim joist. Now that the rim joist is air sealed and insulated with spray foam the home will be warmer and more efficient.
