Decades of SIP industry effort and collaboration have resulted in an extensive research library on structural insulated panels and on whole buildings made with SIPs. Scroll down for specific research reports.
Over the years SIPA members have worked extensively with USDA's Forest Product Laboratory, DoE's Oak Ridge National Laboratory, Home Innovation Research Labs and APA – The Engineered Wood Association to build the knowledge base on the structural properties of SIPs. Click below for the official reports on these multi-year studies. Most of this SIP product research can also be found at the Forest Products Laboratory website (fpl.fs.fed.US).1 - Creep Behavior of SIPs Pilot Study 2 - Creep Performance of SIPs Phase 2 3 - Flexural Testing of SIPs Before & After Creep Testing Durability of SIPs Cyclic Shear Wall Testing Durability Testing for SIPs Lateral Load Performance of SIP Diaphragms Lateral Load Performance of SIP Walls with Full Bearing Performance of SIP Walls under Seismic Loading SIP Missile Testing for Florida HVHZ SIP Shear Walls: Cyclic Performance of HIgh Aspect Ratio Segments and Perforated Walls Ultimate Flexural Strength and Long-Term Creep Deflection for Structural Insulated Foam-Timber Sandwich PanelsTrufast SIP Fastners Technical Evaluation Report
