SIP Failures and Forensic Analysis

When a Structural Insulated Panel (SIP) assembly fails, whether from moisture intrusion, OSB rot, or a manufacturing defect, understanding the actual cause matters for builders resolving the problem and for attorneys and insurance adjusters investigating a claim. This section covers how and why SIP failures happen, drawn from real forensic case work. Independent forensic analysis from Joe Pasma, PE, who has conducted SIP failure investigations for over 40 years and is not affiliated with any manufacturer.
