Abstract
Subalpine fir (Abies lasiocarpa (Hook.) Nutt.) is the fir species in the spruce-pine-fir (SPF) group harvested in British Columbia and Western Alberta. Due to preferential logging of lodgepole pine, the availability of subalpine fir is projected to increase significantly, in some regions to as high as 30 percent of the SPF mix. Examination of the properties of subalpine fir suggested opportunities for new higher margin products in applications where durability and dimensional stability are important such as decking. An experiment was designed to compare the dimensional stability of flat decking to ribbed decking using three copper-based preservatives: alkaline copper quat (ACQ-D), copper azole (CA), and chromated copper arsenate (CCA). Preservative treated and non-treated decks were installed at Forintek...
