Research Abstract

Performance degradation of fire-retardant wood is a foremost concern through the use in exterior applications because of the leaching of chemicals. Weatherability and combustibility of fire-retardant-impregnated wood were evaluated after accelerated or outdoor weathering tests. We found that the appropriate combination of chemical agents and coatings improve the weatherability of fire-retardant wood, and chemicals in the cell walls remained after leaching.
