Know Your Timber Types and Terminology


Reading time: 4 minutes

Which timbers are considered hardwoods? 

Hardwoods generally refer to wood that is sourced from broad-leaved trees. They are often stronger, thicker and more durable when compared to softwoods (which we will come onto later).

What is meant by softwood timber?

Softwood timber is wood produced by coniferous trees. Softwood tends to be lighter, more flexible and less expensive when compared to hardwoods. Ideal for indoor and outdoor applications, softwoods can be used for roofing, doors and windows.

CLS timber 

Canadian Lumber Standard (CLS) timber is mainly sourced in the UK from Scandinavian or European softwoods. The use of CLS have grown over the years and is often used for timber framing and constructing internal stud walls. 

CLS is an easy to use and quality type of timber that can be bought already kiln-dried, treated and planed with smooth, rounded edges. These properties make it a reliable choice for a range of building projects.
