That evening, he called an engineer friend. “What you need,” the friend said, “is not better wood. You need a different geometry.”
Moreover, because the joists are cut to length at a truss plant (not on site), job site waste drops from 15% (for dimensional lumber) to under 3%. Framers initially resisted I-joists.
