Performance of Preservative Treated Parallel Strand Lumber in Marine Exposures.
2006 - IRG/WP 06-30407
The performance ACZA treated Douglas-fir and CCA southern pine parallel strand lumber (PSL) was studied in marine exposures in Florida or Oregon. While materials treated to retentions below the recommended levels for marine exposure were attacked in Oregon, properly treated panels of either species performed well. Panels treated with these same chemicals and exposed in Florida experienced attack ...

Exposure of CCA and ACZA treated parallel strand lumber to marine borer attack in northeastern and southeastern waters of the United States of America
2006 - IRG/WP 06-30400
Southern pine and Douglas fir Parallel Strand Lumber (PSL) panels were treated with chromated copper arsenate (CCA) or ammoniacal copper zinc arsenate (ACZA), respectively and exposed in a marine environment in Massachusetts (northeastern USA coast) for 7 years. Similarly treated panels were also exposed to a site on the Atlantic coast Florida (southeastern USA) for the same period. In the northe...

Field Stake Performance of Parallel Strand Lumber Treated with Waterborne Copper Naphthenate
2008 - IRG/WP 08-40435
Wood and wood products have been considered a premium building material for residential and industrial structures for many centuries. More recently, structural composite lumber (SCL) products have played an increasing role in satisfying the needs of the building industry. However, both wood and wood composites are naturally biodegradable materials which require enhanced durability when used in ce...

Douglas-fir PSL Treated with Oilborne Copper Naphthenate – Treatment Experience & Efficacy
2014 - IRG/WP 14-40687
Treating characteristics, field stake efficacy and the results from treatment trials for oilborne copper naphthenate (CuNap) and Douglas-fir parallel strand lumber (PSL) are summarized in this paper. Treatment with a P9 Type-C based solution in laboratory tests showed full cross section penetration of large cross sections could be achieved. Commercial treatment trials using a P9 Type-A solution ...
