Presented by James P. Gogolski

Learning Objectives:

  1. Understanding what is FRTW: Explains how FRTW is manufactured, how it is different from untreated wood and steel, and the testing required by the codes
  2. Describe where it is used in building design and construction.
  3. Explain why it is allowed in noncombustible construction.
  4. Be able to identify properly treated fire-retardant-treated wood.



This session is a discussion of fire-retardant-treated wood (FRTW) characteristics, examples in design and applications, and referenced sections in the International Building Code. The building code, as with many products, regulates the use of wood in construction. Two broad categories separate materials: combustible and noncombustible. Codes limit the applications of combustible materials on the basis of fire and life safety. The question is then, are there options available to using wood in lieu of a combustible material. Fire- Retardant Treated Wood provides that option. Codes recognize FRTW for many applications where a noncombustible material is mandated.
