4x2 CLS Timber Studwork & Framing 38x89mm - 2.4m

This 4x2 CLS Timber has a finished size of approximately 38mm x 89m, which has a slightly smaller profile than our 4x2 C24 Timber as it is finished on all sides. It is 2.4m long and ideal for stud walls, partitioning and framing.  

• For use in stud walls, framing and partitioning applications
• Regularised on all sides for uniform size, with eased corners
• Conforms to BS 4978 and EN 14081:2006
• Kiln Dried for additional strength and durability
• Sustainably Sourced Timber
• Not suitable for use in direct ground contact.

What is 4x2 CLS Studwork Timber in mm?

The term "4x2," typically denoting the joist size in inches, equates to 47 x 100mm in metric measurements. However, CLS is planed on all sides to achieve an even and uniform finish, resulting in a "finished" size slightly smaller of approx 38mm x 89mm, to ensure consistency throughout.

This slight variance is typical in CLS timber and tends to lend itself specifically to structural projects where plasterboard etc will be applied to the structure. 

What is 4x2 CLS Timber Studwork Used For?

Typically, C16 CLS Studwork Timber is used for timber frame home construction, such as stud walling, carcassing and interior framing and partitioning. It is a C16 timber which makes it exceptionally strong, and suitable for interior construction applications.

What Does Kiln Dried Mean?

Kiln-dried timber goes through a drying process involving a consistent heat application in kilns, efficiently removing excess moisture from freshly cut boards. This method reduces weight, enhances strength and straightness, and improves workability. In contrast to the prolonged duration of air-drying, kiln drying provides a faster and more reliable approach.

What Lengths Do 4x2 CLS Timber Studwork Come in?

We offer 4x2 timber in both a 2.4m length and a 4.8m length. We strive to maintain stock across all sizes for delivery, but there are occasionally instances where we would look to substitute a longer length as an alternative if there's a delay or unavailability of specific sizes in your area.

What Does CLS Stand For?

CLS stands for "Canadian Lumber Standard" as CLS Studwork Timber was initially sourced from Canada. However, presently, it's sourced from various countries, including the UK. Despite this, the term CLS remains a common identifier for this product.

What Does C16 Stand For?

In the UK, regularised timber is typically classified into two grades: C16 or C24. The "C" signifies the wood type, specifically Conifer. The numerical value indicates the bending strength, based on factors such as imperfections and knots. While C24 is the stronger grade, C16 remains exceptionally strong and is used in numerous wall and roofing applications.

Do I Need Treated 4x2 Timber?

Our 4x2 CLS Timber is untreated as it is typically used in internal applications. If your project is likely to be prone to moisture or pest issues, treated timber may be a better alternative, which is better suited for outdoor projects like decking, roofing, and similar projects.
