CLS stands for 'Canadian Lumber Standard'.­ CLS was originally manfactured in Canada for use in the building of timber framed houses, hence it's name. Over the past few years CLS has become increasingly popular in the UK for use as framing for stud walls and internal partitions.

What is the difference between Scant & CLS?

Scant and CLS Timber are abbreviated trade references to specific types of timber, which have a specific main use, in the form of building none load-bearing partition walls. Once these partition walls are constructed, the next stage in the process would be to face the walls with plaster­board. Our Scant all four sides of the section are surfaced, whereas CLS tends to be "eased edge" (rounded corners).
