WHAT TYPES OF WOOD PRODUCTS ARE AVAILABLE WITH FACTORY TREATMENT?
Dimension lumber and plywood are available treated with CCA or borate. OSB treated with borate and CCA-treated Parallam are also available. Glulam can be effectively treated with oil-based preservatives, but these are not suitable for use in buildings. Glulam and LVL are very difficult to pressure-treat, however, it may be possible to treat these products with borate during production as with borate-treated OSB currently available commercially. These manufacturing processes are under development at Forintek.
