What is CLS Timber 38mm x 63mm x 2.4m?

CLS stands for “Canadian Lumber Standard”, as the beams were originally produced in Canada. Modern CLS timber merely implies a standard and finish rather than a point of origin. Most CLS timber sold within the UK will have originated from Scandinavia or central Europe. Conventionally made from pine, fir, or spruce softwood, CLS timber is defined as such by its strength and its unique planing. CLS is kiln-dried, treated, and plained, normally reaching C16 or C24 strength grading. All four corners of a CLS beam will be plained to give a rounded edge. Each side will also be smoothed. CLS Timber benefits from its consistency and quality control. When buying a large volume of CLS beams there should be a far more reliable level of straightness compared to ungraded timber.

Is CLS Timber treated?

CLS timber will be treated as standard. This will give it benefits such as moisture resistance and insect resistance, allowing CLS beams to be used in a wide variety of settings where they may be at risk. The kiln-drying process will also help to remove moisture from each beam.

Can you use CLS Timber outside?

Thanks to its treatment and moisture resistance, CLS timber can be used in outside applications. There is a grading system for treated timber, called the use class system, and timber that will be in contact with water or soil will need to be treated to use class 4. CLS timber can be used for a wide variety of exterior uses. It will need to be maintained to keep its look during prolonged outdoor use, however, and there are a variety of different products that can aid this, such as preservatives, UV-blocking paints, and colour maintaining sealants.
