Premium Sub-Floor Sheathing Built To Last

To create LP Legacy® Premium Sub-Floor panels, logs are stranded and dried, then blended with waxes and resins. This includes Gorilla Glue Technology® that provides unmatched strength and moisture resistance throughout the panel. The strands are aligned in a specific orientation, sent through a press to bond at the molecular level, and cut to size. With this innovative process, LP Legacy panels represent one of the strongest, stiffest sub-floor options on the market.

Premium OSB Technology

There’s a reason it’s among the industry’s best OSB sheathing. LP Legacy OSB panels are built to deliver cost-effective, superior performance and stability. Stake your reputation on the remarkably strong, consistent quality of LP Legacy OSB sub-floors.
