CLS Timber

About Our CLS Timber

We supply CLS timber for framing, studwork, and internal partitioning at the Builders Supply Scotland. Known for its consistent dimensions and eased edges, CLS is the go-to timber for fast, accurate assembly on site.

Here, we carry the core CLS timber sizes used by joiners and builders every day across Glasgow and Edinburgh, with reliable stock levels and straightforward delivery you can plan around.

Orders can be placed online, collected from our branches, or managed through your account login for trade pricing and job tracking.

Our Range of CLS timber

The CLS range includes treated whitewood sections in the standard widths and depths used for internal walls, room divisions, and general timber framing.

We provide CLS timber in 38 x 63 mm CLS timber, 38 x 97 mm CLS timber, and 38 x 140 mm CLS timber profiles, so that you have the flexibility to match existing work or build to a particular spec. Each length is regularised for true sizing, making it easier to line up studs, noggins, and head plates without fighting variation. The eased edges reduce splintering and speed up handling, and the pressure treatment provides protection when the timber is used in areas where moisture is present.
