WBP Plywood (Weather and Boil Proof Plywood) is suitable for Protected Exterior Conditions such as behind cladding or under roof coverings. The bonding quality is examined by immersion of plywood in boiling water for 6 hours and followed by bonding strength/quality testing. WBP Plywood will not delaminate even after immersion in boiling water for a period of time. WBP Plywood is typically used in Film Face Plywood for its durability and weather resistant. WBP Plywood can be used for interior applications, such as kitchen cabinet, plywood underlayment with higher exposure to moisture or high humidity conditions.
