LP’s newest composite subfloor panels are bonded at the molecular level with Gorilla Glue Technology and retain their shape and size when exposed to moisture or the elements, the company says. The LP Legacy sports exceptional fastener holding, reduced chances of nail pops or movement over time, and higher performance for finished materials, including hardwoods, according to the manufacturer. Pricing varies by market, but according to LP, panels are typically available for a modest premium over commodity Sturd-I-Floor panels. lpcorp.com
