Our 38mm x 89mm CLS (Canadian Lumber Standard) timber is the preferred choice for professional builders and DIYers alike for creating internal partitions. While commonly referred to by its nominal size of 4″ x 2″, it is finished to a precise 38mm x 89mm. This consistency is vital for ensuring that your walls are perfectly plumb and your plasterboard fits flush across every stud. This timber is Untreated, making it a clean and safe option for all internal dry-use applications. Every piece is Kiln-Dried (KD) to ensure maximum stability, preventing the timber from warping or bowing once it is enclosed within a wall. The regularised planed finish and eased edges make it much more comfortable to handle on-site and significantly reduce the risk of splinters compared to rough-sawn timber. C16 Structural Grade: Machine-graded to meet UK building regulations for load-bearing internal partitions. Precision Regularised: Planed to exact 38mm x 89mm dimensions for a uniform, professional build every time. Eased Edges: Rounded corners provide safer handling and allow for easier installation of wiring and plumbing within the wall cavity. Kiln-Dried for Quality: Moisture-controlled to prevent movement, ensuring your frames stay straight and true. Wider Profile: The 89mm width provides extra structural support and more room for acoustic or thermal insulation compared to 63mm CLS.
