Insulating Under a Home in New Hartford, CT

This homeowner in New Hartford, CT called us saying that she had a three season room (which she described as a porch) that she wanted to insulate under. She stated that it was very uncomfortable in the winter. When our Home Comfort Specialist came out to the home, he talked more to the homeowner and her husband. Their home was lacking in insulation throughout the entire home, causing high energy bills. They specifically wanted to ensure that the three-season room was insulated due to the issues they were experiencing with it. Some homes or additions are designed with floors that have the outside air under them. Other times a home or addition was originally used as a summer home or “three season room”, and was converted to all season heated space later. When the outside air flows under a floor it feels very cold and uncomfortable in the winter - especially with ceramic tile, linoleum or laminate floors. Since the floor is the surface of the room we are in contact with most, it’s very important to fix, in order to be comfortable. There are two issues - air leakage through the floor, and conductive heat loss through the floor, because heat moves from more to less through solid materials. Even if there is fiberglass batt insulation in the floor, because it sags down away from the sub floor, the same outside air gets over it (“thermal bypass”) rendering it useless. Mold on the floor joists and sub floor is also a concern. Results - cold floors, drafts, uncomfortable rooms, greater overall home air leakage rate, higher fuel and electric bills.

We had the perfect solution for this customer. In this solution, SilverGlo™ foam insulation board is installed across the bottom of the floor joists with special long screws and 3” washers, SilverGlo™ is expanded polystyrene foam with graphite infused into the foam, which bumps up the insulation (“R”) value by 24% over standard EPS foam. Further, SilverGlo™ has a radiant barrier to reflect heat, so the insulation isn’t doing all the work by itself. All seams are sealed. If necessary a skirt board can be installed around the perimeter of the insulation so the edge is not visible. The skirt board may require painting after we are complete. Result - Much warmer floors, less drafts and more comfortable rooms, quieter home, lower fuel and electric bills.
