Wooden flammable cabinets provide an excellent thermal barrier to extreme temperatures during a fire, which helps keep the temperature inside the cabinet to a minimum. Metal, on the other hand, is a heat conductor that can raise the internal temperature inside the cabinet faster than a wooden cabinet. NFPA 30 Chapter 4.3.3 (c) states, Wooden cabinets constructed in the following manner are acceptable. The bottom, sides, and top shall be constructed of exterior grade plywood at least 1 inch (2.5 cm) in thickness, which shall not break down or delaminate under fire conditions.
