SIP Manufacturing and Manufacturer Selection

Not all Structural Insulated Panel (SIP) manufacturers build to the same standard, and choosing the wrong one can affect a project's structural performance, code approval, and long-term durability. This section covers how SIPs are manufactured, what separates a well-run manufacturer from a risky one, and how to evaluate a manufacturer before committing a project to them. Independent analysis from Joe Pasma, PE, who has worked directly in SIP manufacturing and quality oversight for over 40 years.
