A step-by-step guide to writing a strong specification for generic fire-retardant-treated wood (FRTW) for specifiers. The history of FRTW, how it is manufactured, and how it compares to steel, concrete, and painted/coated wood products helps create a context to better understand when to use specific products in specific situations.
Mass timber buildings are capable of providing a level of fire-resistance comparable to steel and concrete. Building code changes are allowing more projects to capitalize on the cost, schedule, and environmental advantages of wood construction. As the popularity of wood grows, construction safety practices are also receiving greater emphasis to mitigate fire hazards during one of the most vulnerable periods of a building’s lifetime.
Safety has always played a key role in the design of schools, but the necessity is more heightened than ever today. High-profile issues like school shootings add to long-held safety concerns, the most notable being fire.
A proposed ASTM standard will provide building officials and fire marshals with better ways to inspect spray-applied (SFRM) and intumescent (IFRM) fire-resistive materials, commonly used on structural steel and other substrates to maintain veracity and safe conditions when a fire occurs.
