CLS Timber (Canadian Lumber Standard)

CLS timber refers to softwood timber—commonly pine, fir, or spruce—that meets the Canadian Lumber Standard. It is widely used in construction, particularly for internal framing and stud wall structures. The timber is kiln-dried to enhance stability and prevent warping, and it is planed with smooth, rounded edges for easier handling and a neat finish.

CLS timber is typically strength-graded as C16 or C24, indicating its suitability for structural use. It is most often untreated, meaning it’s ideal for indoor projects but not suitable for outdoor or damp environments unless treated. It comes in a range of dimensions, making it versatile for various interior building applications.
