Crawlspace InsulationAt the time of your energy audit, we can develop a package for you to insulate and air sealing crawlspace penetrations. We use high density spray foam insulation as well as polyiso foamboard insulation to seal off cold air from leaking into the living space. We can show you how the thermal and pressure boundaries existing in your crawlspace are connected to your living space that you are paying to heat and cool. |
