Framing (CLS & Scant)
CLS (Canadian Lumber Standard) and Scant are timbers imported from both Canada and Europe and used for internal studding, partitions, framing etc. CLS and Scant are 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 and Scant are much smaller than the nominal (ie pre planing) sizes. The finished size of Scant is usually larger than CLS.
CLS 75mm x 50mm (3" x 2") usually finishes at 63mm x 38mm (21/2" x 11/2") and 100mm x 50mm (4" x 2") finishes at 89mm x 38mm (31/2" x 21/2"), whilst Scant 100mm x 50mm (4" x 2") usually finishes at 94mm x 44mm (33/4" x 13/4").
