Fire-Retardant-Treated Wood and the IWUI Code  

Fire-retardant-treated wood contributes to both sustainable forest management

Sponsored by Hoover Treated Wood Products

As communities continue to grow into wildland areas, the need for fire-resilient, sustainable building materials becomes increasingly critical. This course introduces design professionals to fire-retardant-treated wood (FRTW)—what it is, how it works, and where it fits within the context of today’s building needs and environmental goals. Participants will explore how FRTW contributes to sustainable forest management, supports affordable housing, and how it compares to other materials from a performance and sustainability standpoint. The course also covers the available FRTW products, their specifications, and why treated wood is considered a “green” material for modern construction, especially in WUI zones.
