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.
