We are framing a high-performance floor system using PWT 20 Series I-Joists spaced at 24” on center paired with 3/4” AdvanTech X-Factor subfloor. In this video, we bust the myth that 24" O.C. framing is "pure hackery" and break down the engineering dials you can twist—joist depth, spacing, and subfloor stiffness—to deliver a stiffer, more energy-efficient floor system for less money.

We also share a time-saving framing tip for scribing I-joists directly on pony walls, break down why straight-line blocking outperforms staggered blocking for load transfer and subfloor diaphragms, discuss LSL (laminated strand lumber) vs. OSB, and show how we safely use jobsite chainsaws to speed up layout.
