All our CLS is graded to a minimum of C16, is wane free and straight.
CLS (Canadian Lumber Standard) is used for timber frame construction and internal partition walls. Although as the name suggests it is of Canadian origin, CLS is in fact an acknowledged grade of timber and is now predominantly sourced from Europe.
All our CLS is graded to a minimum of C16, we insist however, that it is wane free and straight. Both of which are important for this product and its application.
Choosing close grained raw material is vital in guaranteeing that CLS remains straight and stable after production and in use. Slow grown, close grained imported timber, gives greater strength and stability along the length.
