The International Residential Code (IRC) requires Structural Insulated Panels, like other building products, to participate in a quality control program, and also states that they must bear a mark from an accredited product certification agency. This requirement has been in place since SIPs were first included in the IRC in 2007. The IRC only covers SIPs used in walls, but NTA can provide alternate certification for Structural Insulated Panels used in floors and roofing, as well as for spans exceeding twelve feet.
Below are just a few of the companies who have participated in the NTA SIP Certification Program, and have also been issued a certification mark and listing report (take a look at our online database of listing reports), that verifies the code compliance of their product and their continued commitment to quality and safety.
