The Marlborough Reg Treated Carcassing C16/24 is a premium, slow-grown Scandinavian softwood designed for professional builders, contractors, and DIY enthusiasts requiring reliable structural timber for framing and roofing projects. Its primary benefit lies in its C24 strength grading and kiln-dried manufacturing, which ensures superior load-bearing capacity and enhanced dimensional stability; however, users should note that this product is classified for Use Class 3 (UC3) and is intended strictly for above-ground applications, meaning it is not suitable for direct soil or water contact.

C24 is a structural grade that indicates the timber has been tested for strength, stiffness, and density, making it suitable for high-load applications like joists and rafters.
No. This timber is rated for Use Class 3, which is for above-ground use only. Ground contact requires timber treated to Use Class 4.
Yes, this product is kiln-dried, which helps minimize moisture content and reduces the likelihood of the wood moving or warping after installation.
Scandinavian timber is typically slow-grown, resulting in a denser wood with a tighter grain, which offers superior strength compared to fast-grown alternatives.
While the treatment protects against decay, you can apply a wood stain or paint to the surface for aesthetic reasons or added UV protection.
Yes, it is Chain of Custody certified, meaning it is sourced from sustainably managed forests that adhere to strict environmental standards.
Allow the timber to acclimate in a well-ventilated, dry environment for several days before installation to reach equilibrium.
Use a pilot drill bit slightly smaller than the shank of your screw to prevent splitting and ease installation.
Immediately treat all cut ends with an appropriate end-grain wood preservative to maintain the original treatment efficacy.
To ensure the longevity of your Marlborough carcassing timber, store the lengths flat and under cover in a dry, well-ventilated area before use to prevent moisture absorption. While the timber is treated, it is not impervious to all weather conditions; always ensure the final design allows for proper drainage and ventilation to maintain the UC3 status. When cutting, use sharp, high-quality blades to ensure clean edges and always apply a brush-on preservative to any cross-cut surfaces. Compatibility is high with standard structural fixings, including galvanised coach bolts, screws, and joist hangers. Do not use this timber in contact with damp earth or in submerged conditions.
