Structural Framing Lumber
Interfor is committed to manufacturing quality wood products for residential, commercial and industrial applications. Lumber is produced from four species:
Western Hemlock (Tsuga heterophylla)
Western hemlock is among the harder, stronger western softwoods. It is used for framing and architectural members and is a prime species for mouldings, millwork and paneling. Whitish to light yellowish-brown springwood, summerwood frequently has a purplish or reddish-brown tinge, heartwood not distinct. Small black streaks often appear in the wood. It is marketed and sold separately and in the Hem-Fir species combination.
Douglas Fir (Pseudotsuga menziesii)
One of the strongest softwoods, Douglas Fir is often the preferred species for structural purposes. Sapwood is white to pale yellow; heartwood is russet with high contrast between springwood and summerwood. Straight grained and moderately hard, it is appropriate for engineered applications and laminated timbers, but also widely used for doors, cabinets, millwork and pallets, boxes, ladders or flooring. Marketed and sold separately or as Douglas Fir-Larch.
Ponderosa Pine (Pinus ponderosa)
Ponderosa's soft texture and light colour distinguish it from the Southern pines. Sapwood is nearly white to pale yellow; heartwood is yellowish to light reddish brown. Pleasant pine odour and slightly resinous; moderately strong and straight grained. Favoured for all kinds of joinery including window frames, doors and architraves, and is used for shelving, paneling and furniture. Marketed and sold separately or in the Western Woods species combination.
Lodgepole Pine (Pinus contorta)
Lodgepole pine is the strongest of the Western pines. It has relatively straight grain, white to yellow sapwood and light, reddish-brown heartwood. Relatively easy to work, it machines to a satin-like finish. Knots will not bleed through paint. It is used for interior paneling, joinery, structural timber and poles. In the structural sizes and grades, Lodgepole is included in the Spruce-Pine-Fir (South) species combination. It is also marketed and sold separately or with Engelmann spruce in an ES-LP combination.
Southern Yellow Pine
Southern Yellow pine is renowned for its durability and versatility, making it well suited for a wide range of applications. It offers a distinct grain pattern and appealing golden color. It is a great choice for building, industrial and outdoor uses and has excellent dimensional stability. Its unique cellular structure permits deep and even penetration making it the best choice for pressure-treating applications. Click here to read our Southern Yellow Pine factsheet.
