How and where to use guide
3.6Mtr X 47 X 200mm C24 Treated Regularised KD Carcassing Timber
Structural applications
C24 timber is ideal for applications where load-bearing capacity and long-term stability are essential. The strength grading ensures consistent performance, making it a reliable choice for professional builders and serious DIY projects. Its enhanced stability and fewer knots compared to lower grades provide superior reliability.
- Floor joists in residential and commercial buildings
- Roof battens and structural roof work
- Stud walls and partition framing
- Decking frames and outdoor structures
Indoor construction
For interior building work, C24 timber provides a clean, professional finish with its smooth, planed surface. It is suitable for joists, wall framing, and general structural timberwork where appearance and performance are both important. The timber's stability makes it less prone to movement and warping.
- First and upper floor joists
- Internal stud walls and partition frames
- Loft and attic structural work
- General carpentry and framing
Outdoor and exposed applications
The pressure-treatment applied to this timber provides protection against rot, fungal decay, and insect infestation, making it suitable for outdoor use. It is particularly valuable in damp or exposed locations where untreated timber would deteriorate. This makes it an excellent choice for decking frames, garden structures, and external building work.
- Decking frames and outdoor platforms
- Garden structures and pergolas
- External wall framing and cladding support
- Fence and gate posts (where appropriate sizing is used)
Compliance and standards
C24 Treated Carcassing Timber meets current BS EN standards for strength grading and treatment. It is suitable for use in building projects subject to Building Regulations. Always verify that the timber grade and treatment are appropriate for your specific application and local building code requirements.
- Meets BS EN strength grading standards
- Pressure-treated to recognised durability standards
- Suitable for use in Building Regulations-compliant construction
- Consult structural engineer for critical load-bearing applications
