Fire Retardants

Structural Building Components Association (SBCA)

There are several considerations a designer must take into account when using fire retardant treated (FRT) wood in a building design. A building’s construction type will dictate whether certain materials, including FRT wood products, are permissible in the the building. Additionally, depending on the type of FRT used, wood used in trusses may require a change in design values and reduction in connector capacity in the truss design. This guide provides an overview of the provisions a designer should make when using FRT wood in building designs.
