Is a SIP a “green building product?
SIP homes require considerably less framing lumber than a conventionally framed home. Note too that 95% of a tree can be used when it is cut into wood chips to make OSB for SIP facings, vs. 63% of a tree when it’s sawn into solid lumber. SIP homes pre-cut in the factory mean less job-site waste is shipped to the landfill and more of it is recycled at the factory. While it several times more energy to make foam than fiberglass, and the foam itself is a petroleum product, lifetime savings in heating and cooling requirements will offset this difference in favor of the SIP home.
