SIP Fundamentals and Building Science

Structural Insulated Panels (SIPs) are a building system, not just an insulation product, and understanding how they actually work matters before you commit a project to them. This section covers the basics: what SIPs are made of, how they perform structurally and thermally, and how they compare to traditional stick framing. Written by Joe Pasma, PE, an independent structural engineer with over 40 years in SIP design, manufacturing, and field consulting, not a manufacturer with panels to sell.

Understanding Structural Insulated Panels (SIPs) requires more than just knowing the materials. SIP performance depends on how core types, facing materials, adhesives, and system design work together. This guide breaks down EPS, GPS, and PUR/PIR cores alongside OSB, MgO, and cementitious facings to help builders, architects, and manufacturers make informed, system-based decisions.
