Aftermarket Treatment of Trus Joist Products for Fire Resistance

Weyerhaeuser does not recommend pressure treating their engineered lumber products with a fire retardant.  Reductions to the structural properties and impacts on dimensional stability may occur and have not been evaluated.

Any pressure, fire retardant treatment voids Weyerhaeuser's product warranty.  Topical, non-pressure, fire treatments suitable for wood products can be applied. However, Weyerhaeuser does not evaluate their compatibility, durability or make any claims as to their effectiveness.  Consult with the fire retardant treatment manufacturer for data on compatibility, durability and effectiveness of topical treatments.

Please refer to product literature TJ-1500 Fire Facts Guide.
