How are SIPs different?

SIPs are a high‑performance building system that behaves completely differently from traditional stick‑frame construction. They function as a structural composite. The entire panel, interior and exterior skins combined with the insulated core, shares and transfers loads.

​

Because SIPs are engineered systems, they require design expertise beyond conventional construction methods.

​

SIP‑Specific Requirements

• Unique load path considerations

• Specialized connection details (splines, joints, hold‑downs)

• SIP‑compatible header and opening engineering

• SIP‑specific roof diaphragm and shear wall design

• Correct thermal, air sealing, and moisture detailing​

​

Designing SIP projects using stick‑frame assumptions leads to errors, code issues, and costly construction fixes.
