How strong are SIPs?

The structural characteristics of SIPs are similar to that of a steel I-beam. The OSB skins act as the flange of the I-beam, while the rigid foam core provides the web. This design gives SIPs an advantage when handling in-plane compressive loads.

SIPs can be engineered for most applications. Detailed information on the structural performance of SIPs is available from SIPA member manufacturers.
