CLS (Canadian Lumber Standard) timber is imported from both Canada and Europe and used for internal studding, partitions; framing etc. CLS is produced from kiln dried spruce (whitewood), planed and finished with eased edges to precise tolerances and are graded C16. Rough sawn 50mm x 47mm (2" x 2") is also widely used for both internal and external framing.

Due to planing, please note the finished sizes of CLS is much smaller than the nominal (ie pre planing) sizes.
