The Georgia Structural Pest Control Commission proposed a state building code amendment that will require the framing/foundation interface (band joist and mudsill area) to be air sealed and insulated with a removable insulation product for pest control inspection of the wood framing members in crawl spaces that are not vented to the outside and an alternative to insulating floors over crawl spaces.
The current Georgia building code requires termite inspection/view strips at the top and bottom of the foundation wall but allow the framing/foundation interface (band joist and mudsill area) to be covered with permanently fastened insulation, such as spray polyurethane foam, (SPF). However, the installation of SPF on the framing / foundation interface (band joist and mudsill) covers the critical areas that the pest management companies need to visually inspect for termite infestations. The mudsill, band joist and joist ends are the first points at which termites can be detected as they enter the wood structure. Subterranean termites can pass through small - 1/64” cracks and gain access to structural lumber by constructing shelter tubes and climbing up the inside or outside of the foundation wall. Termites can also enter buildings through cracks in the footing and travel through voids in concrete masonry units. Inspection opportunities from the exterior of the building are often obstructed by brick or landscaping features, so inspection from inside the crawlspace is the only option. There are currently no alternative “viable” inspection methods or tools available to perform the inspections through SPF. This amendment will provide for termite inspections, insulation, and air sealing in the band joist area.
The Georgia Department of Community Affairs Building Code Commission is meeting on January 27, 2021 to review proposed code amendments.
Next SPCC meeting is scheduled for January 12, 2021.
