Spruce timber

Spruce, Pine, and Fir, the three softwood species that make up SPF lumber products, are processed together due to their similar appearance and properties. SPF represents the largest reserve of commercial softwood in Canada. SPF is the most commonly used lumber for house construction (known as “2×4” dimension lumber) in North America due to its strength, light weight, and ease in cutting and nailing. It is used primarily for wall framing, roof framing, roof trusses, floor joists, and beams. In addition, certain grades are suitable for non-structural applications such as packaging and re-manufacturing for interior finishing or treating as exterior decking. Products can be Kiln Dried (Maximum 19% moisture content), Heat Treated (KD-HT), Air Dried (AD) and Green (GRN). Dressing is Surfaced Four Sides (S4S) with Eased Edges (EE) for smooth and slightly rounded edges. Dimension Sizes: CLS SPF lumber is described by its nominal size, which differs from actual size.
