Spruce-pine-fir, or SPF, is the generic name for a variety of softwood species imported from North America
There is little difference between the heartwood and sapwood, both of which are a yellowish white. It is even-grained, medium to fine-textured, and produces a lustrous finish. It is without characteristic odour or tast
White spruce and lodge pole pine mainly make up the SPF interior spruce (SPF) group. A small percentage of subalpine fir is also included in this species grouping. The dimensional stability of SPF and the superior gluing properties make it popular in the prefabrication industry.
Due to its high strength–to-weight ratio, it is ideal for modular houses, interior finishing, boxes and packing cases. This species group is often used in the manufacturing of flat-packed modular furniture.
