One of the Strongest on the Market

This stiff, quiet sub-flooring offers confidence with a No-Sand Covered Until It’s Covered® warranty.

How It’s Made

To create LP Legacy® sub-flooring, 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 sub-flooring represents one of the strongest, stiffest sub-flooring options on the market.
