    Structural insulated panels (SIPs) have been recognized as construction materials in the International Residential Code (IRC) since 2009. Although most SIPs are used in wall applications, they can also be used as roof or floor panels that are subjected to long-term transverse loading, for which SIP creep performance may be critical in design. However, limited information on creep performance of SIPs under transverse loading is available. Collaborative pilot studies were undertaken by the USDA Forest Products Laboratory and APA–The Engineered Wood Association to explore the creep behavior of SIPs under bending- and shear-critical configurations. Results from these pilot studies will serve as the basis for more comprehensive future studies. This paper provides detailed test results from these pilot studies.
