CLS Timber FAQs
What sizes of CLS timber do you stock?
We stock 38×63mm (3x2), 38×89mm (4x2) and 38×140mm (6x2) finished CLS sections, with 2.4m, 3.0m and 4.8m lengths depending on section.
Is CLS timber strength graded?
Yes. This range is strength graded softwood for suitable internal construction and framing applications. For any load-bearing or regulated work, follow the relevant design or building requirements.
Why is 3x2 CLS actually 38×63mm?
3x2 is the common nominal/trade description. CLS is planed to a smaller finished section, which is why the supplied finished size is 38×63mm.
Can CLS timber be used outside?
CLS is primarily intended for dry internal use. For exposed or exterior work, use appropriately treated timber for the required service class/use.
