How It’s Made

LP® SolidStart® Rim Board is made from three substrates to meet a variety of building needs: OSB, LVL or LSL.

  • OSB: Thermal-set, waterproof adhesives and wood strands are bonded, cross-directionally layered, and then pressed under extreme heat and pressure.
  • LSL: Mix of aspen and maple hardwoods are bonded together with a waterproof adhesive in a steam injection press.
  • LVL: LP’s cross-ply LVL rim board is different from other LVL in that two veneers are cross-oriented to increase vertical load capacity.
