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.
