CLS (Canadian Lumber Standard)

CLS, otherwise known as Canadian Lumber Standard, is used for stud partitioning in many houses.

It is planed all round, rounded on all 4 corners, and kiln dried in its country of origin.

Sizes that we hold in stock are 50mm x 75mm (38 x 63) when machined and 50mm x 100mm (38 x 89) in 2.4m, 3.0m and 4.8m lengths.

We can also source other sizes that are clear treated, from our Engineering branches in Wickham and Newport, which are used in timber frame and truss rafter construction.

At Sydenhams the CLS we buy is Either F.S.C. or P.E.F.C. certified to have come from a well-managed forest.
