Lower Energy Bills with Rim Joist Spray Insulation


Stop air and moisture infiltration at the rim joist (banjoist), the space between your home and basement walls, of your home. Stopping air infiltration is the best defense against energy loss. Your home lets in cold air during the winter and warm air in the summer, resulting in higher energy bills.
Stuffing fiberglass insulation between floor joists is a standard method of insulating the rim joist in many homes. Fiberglass insulation has gaps and voids when installed, allowing air to infiltrate. Because fiberglass insulation doesn't fit snugly, it is air permeable. Rim joists (Ban Joist) expand and contract with the change of seasons allowing air to enter and exit at will. Rim Joist spray insulation is a closed cell application which fills in the whole space without any gaps or voids. Unlike fiberglass insulation, which is only a thermal barrier, the spray foam insulation creates both an air and vapor barrier at the rim-joist. Creating an air barrier at the rim joist becomes vitally crucial because moist air can create condensation. Humid air can filter through fiberglass creating condensation at the rim-joist, which can eventually lead to mold and mildew problems.
Spray insulation sticks to the rim joist eliminating the condensing surface. Improper insulation at the rim joist can result in high energy bills, air quality issues, and moisture damage. The spray insulation is highly adhesive, so it sticks and stays in place as it expands to fill gaps. Once cured, the spray insulation provides an effective air seal as well as insulation. Because the spray insulation doesn't allow air to move through it (which diminishes R-value) it always performs at its full rated R-value.
