CLS (Canadian Lumber Standard) timber is a high-quality, versatile softwood that's become a go-to material for internal framing and structural work in both residential and commercial builds. With its smooth planed finish, rounded edges, and consistent sizing, CLS timber is ideal for stud walls, partitioning, and timber frame construction.
What Is CLS Timber?
CLS timber originates from kiln-dried softwood—usually spruce, pine, or fir—that has been planed on all four sides with slightly rounded edges for safety and ease of handling. Originally manufactured to Canadian standards, CLS timber is now widely used throughout the UK and Europe for light structural framing.
Its clean finish, dimensional stability, and ease of use make it perfect for internal building work, especially where accuracy and a smooth surface are important.
