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.

Product Specifications

  • Available sizes: 47-7/8˝ x 95-7/8˝ panels (Longer panels and custom thicknesses are also available. Please call (800) 964-6310 for more info.)
  • Available performance categories: from 3/8 to 1-1/8*
  • For additional strength and stiffness in shear wall applications, specify our APA Rated Struc-1® sheathing
  • LP OSB panels are certified by the APA – The Engineered Wood Association and are manufactured in conformance with U.S. Voluntary Product Standard PS2. Additional information may be found in specific LP product literature and in literature from the APA, whose stamp of quality appears on LP OSB products. You may contact LP at 1-800-648-6893.

  • LP OSB sheathing can be used for wall, roof and flooring applications.

We also offer LP LongLength and LongLength XL OSB Sheathing, ideal for increased jobsite efficiency when constructing standard height and taller ceilings and for helping to achieve code compliance in wind and seismic zones.
