LVL Durability: Relevant Standards

  • The updated standard EN 335:2013 has no information on the application of durability issues for LVL.
  • For guidance, APA refers specifiers to CEN/TC 1099 which provides info on factors affecting durability (and on precautionary measures to be considered for plywood).
  • To find guidance on the durability of LVL, refer to the Use Class definitions for plywood in EN 636:2012+A1:2015.
  • EN 14279:2004 – Laminated Veneer Lumber (LVL) – Definitions, classification and specification, refers to the Use Class definitions in the now withdrawn EN 335-3:1995 for plywood. This info is in EN 14279:2004, clauses 5.3.2, 5.4.2 and 5.5.2 on biological durability.
