Exterior (WBP) Plywood

Description

Exterior Birch Plywood maintains its performance characteristics under conditions of high humidity and does not deform or soak. It can be used in both interior and exterior finish.

Key benefits

  • Higher water resistance
  • Durable and wear resistant
  • Hard surface
  • Resistance to temperature variation: through a range of -40°C to +50°C (-40°F to +122°F)
  • Comes in a variety of thicknesses and sizes
