Timber 4x2 | 4x2 Timber | Timber

Welcome to the Timber 4X2 category, where strength meets versatility in construction and DIY projects. In this category, we explore the range of 47mm x 100mm timbers, available in various treatments and grades, including C24 and C16. These timbers are ideal for a wide range of structural applications, offering durability, stability, and a reliable framework for various construction needs.

Treated C24 Carcassing Timber

Our Treated C24 Carcassing Timber, measuring 47mm x 100mm x 4.8m, is a premium choice for projects demanding higher strength and load-bearing capabilities. The treatment process enhances the timber's resistance to moisture, rot, and insect attack, making it an excellent choice for outdoor and structural applications. This timber is perfect for floor joists, roofing, framing, and outdoor decking where durability is a priority.

Untreated C24 Carcassing Timber

For those who prefer a more natural option, our Untreated C24 Carcassing Timber, also 47mm x 100mm x 4.8m, offers the same high strength and stability as its treated counterpart but without chemical treatments. This timber is ideal for indoor applications where exposure to moisture is minimal. It's well-suited for internal load-bearing walls, ceiling joists, and framing in environmentally sensitive areas.

Untreated C16 Timber Carcassing

The Untreated C16 Timber Carcassing, in the same dimensions, is a cost-effective solution for less demanding applications. While it offers lower strength compared to C24, it is still suitable for various construction purposes, including non-load-bearing partitions, framing, and general carpentry work. This timber is a great choice for budget-conscious projects where high strength is not a critical requirement.

4x2 Timber – Strong, Versatile Structural Timber

4x2 timber is one of the most widely used construction materials in the UK, commonly sized at approximately 47mm x 100mm (nominal 4” x 2”). Known for its strength and versatility, it is ideal for structural framing, stud walls, decking frames, roofing, and general building work. Available in C16 and C24 grades, 4x2 timber offers reliable load-bearing performance while remaining easy to cut, handle, and install, making it suitable for both professional builders and DIY projects.

Selecting the Right Timber for Your Project

When choosing the right timber for your project, consider the following:

• Strength Requirements: C24 timbers are stronger and better suited for load-bearing structures, while C16 timbers are adequate for less demanding applications.
• Environmental Exposure: Treated timbers are essential for outdoor use or in areas prone to dampness, while untreated timbers are suitable for dry, indoor environments.
• Sustainability: All our timber products are sourced with a commitment to sustainability and responsible forestry practices, ensuring an eco-friendly choice for your project.
