Dimensional Lumber vs Engineered Lumber for Floor Joists
The 2x10s we ordered yesterday showed up as green SPF — still wet from the sawmill. On a 3,200 sq ft addition with 24-inch joist spacing, that moisture content meant I needed to let them acclimate inside for three full days before cutting. Meanwhile, the LVL beams for the garage header arrived dry, pre-cut, and ready to bolt on same-day delivery. This isn’t just semantics — it’s profit margin math when you’re running tight deadlines.
