Don’t get burned! Not all fire-retardant-treated wood is equal
Learn what makes some wood products treated with fire retardants code-compliant while others simply are not. Spoiler alert… often it has to do with how the fire retardant formulas are applied (and the ability the meet performance testing requirements, and…). It’s all detailed in the FireSpec sheet Fire-Retardant-Treated Wood: what it is and what it isn’t.
This two-pager delves into the characteristics that define FRTW according to Section 2303.2 of the IBC and why they matter.

ASTM E2768 Test Results Summary here
“There are clear differences in performance between the pressure treated fire retardant wood products and products treated with non-pressure applied fire retardants,” opens the Conclusion section of this report by independent consultant Kelley Spence describing WWPI’s FRTW Testing Program and its results.
Discover why pressure-treated retardants
offer proven, code-approved protection
There’s no better or more durable protection for wood against fire than pressure treating. The advantages of pressure treating compared to surface coatings are detailed in the FireSpec sheet Fire Retardant Treating vs. Coatings.
The one-page guide explains the benefits of integrating fire retardants through pressure treating into sawn lumber and plywood for protection, noting code requirements where paints, coatings and stains are not approved under the codes for fire protection. The guide provides guidance on identifying approved fire retardant wood, noting that color should not be the only indicator the wood has been pressure treated.
