Insulating Vented Crawl Spaces

When the space below the floor is a vented crawl space the underside of the floor should be insulated. Using Johns Manville Comfort Thermal Insulation you can save on energy costs. Begin by installing from below much like insulating ceilings. The facing should be against the subfloor. Comfort Thermal Underfloor has a vapor retarder, the gray side, and is fully encapsulated to reduce itch and dust. The underfloor is unique because it has reverse flanges for easy installation. Fit snugly into the vats so there is no air space between the flooring and the insulation for heat to escape. Staple or nail the flanges to the sides or bottom of the joists. If heating ducts are present, the insulation should be installed below the ducts to prevent heat loss. For water pipes, insulate below the pipes to protect them from freezing. Bow fasteners upward into the insulation pressing the insulation gently into the subfloor. Crawl spaces open to the outdoors, install chicken wire to protect from environmental damage.
