38 x 63mm CLS Timber (most often referred to as Canadian Lumber Standard) is commonly used to create strong and durable stud walling, internal partitioning and frames in residential and commercial properties. Responsibly sourced from sustainable forests in Europe, CLS timber is slow grown for enhanced strength and durability. It is then kiln dried, planed on all four sides to ensure accurate tolerances, and is finished with rounded corners for ease of handling.

Our range of CLS is Chain of Custody certified and is available in a range of standard size options and lengths. It is strength graded to C16 in accordance with BS EN 14081-1:2016+A1:2019 and can be treated in a range of options including clear-vac treated (internal use only), Naturewood Brown or Naturewood Green (external use only).

Note: Rounded corners will not exceed 3mm.
