SIP Product Test 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).
Whole SIP Building Performance Tests
Additional groups such as Oak Ridge National Laboratory (ORNL) and the rigorous California Public Utilities Commission have tested the energy performance of whole buildings made with Structural Insulated Panels.
Best Practices
SIP Best Practices leverage decades of expertise to maximize the high-performance potential of Structural Insulated Panel (SIP) structures. Successful SIP design requires careful attention to detail in areas such as panel layout, sealing, and integration with other building systems to ensure optimal insulation, energy efficiency, and structural integrity. Best practices focus on minimizing thermal bridging, ensuring proper installation techniques, and adhering to building codes, all of which contribute to the durability and performance of the structure. With years of innovation and knowledge, these practices enhance the overall functionality of SIP buildings, ensuring long-term energy savings and sustainability.
