Triple H was called to this home in Manhasset for uncomfortable rooms above the Crawl Space. The Rim Joist of this home was not sealed or insulated. The Rim Joist is the perimeter of the floor framing system along the exterior of the house. If the Rim Joist is not insulated or properly sealed it will cause cold floors and drafty and uncomfortable rooms. Triple H used Spray Foam to seal and insulate the Rim Joist. Since the Spray Foam expands it will seal all the cracks and gaps where the outside air gets in. The walls of this Crawl Space were poured concrete and were not insulated. Poured Concrete walls are dense and have a lot of thermal mass-meaning the heat you pay for in your home passes through the walls to the outside. Uninsulated concrete walls makes for a colder crawl space and colder floors above the crawl space. Triple H installed SilverGlo insulation on the walls. SilverGlo has graphite infused into the foam, this can raise R-value. Now that there is SilverGlo on the Crawl Space walls and Spray Foam insulation in the Rim Joist, the home will be much warmer, there will be less drafts, and the cost of heating and cooling will be reduced.
