Effect of Weathering on The Dimensional Properties of Particleboard Decking

H. M. Barnes, D. E. Lyon


The effect of outdoor weathering on the dimensional properties of phenolic-bonded particleboard manufactured as decking for factory-built housing was evaluated. Results were compared to those for urea-bonded particle board made with a similar southern pine furnish. Results indicate that in terms of linear expansion, thickness swelling and swelling recovery, and resistance to buckling, weathering did not severely affect the performance of the phenolic-bonded decking material. Weathering significantly affected the performance of urea-bonded material.
