How It's Made

LP uses an innovative manufacturing process to ensure a reliable, consistent product that outperforms traditional lumber:

  • Rectangular wood strands blended with thermal-set, waterproof adhesives are arranged in cross-directional layers.
  • Layers are consolidated under extreme pressure, creating a stiff, strong and durable panel.
