How and where to use guide
2.4Mtr X 47 X 125mm C24 Treated Regularised KD Carcassing Timber
Floor joists and suspended floors
This timber is well-suited for floor joists in domestic properties. The 47 × 125mm section provides good strength-to-weight ratio for typical residential spans. Use joist hangers or traditional bearing on walls, with spacing determined by load requirements and span. Ensure adequate ventilation beneath suspended floors to prevent moisture accumulation.
- Ideal for residential floor joists with standard spans
- Fix using joist hangers or traditional bearing methods
- Maintain adequate ventilation beneath suspended floors
- Space joists according to load and span calculations
Stud wall framing
C24 timber is excellent for internal and external stud wall construction. Its superior strength compared to lower grades provides enhanced stability and load-bearing capacity. Fix studs between sole and head plates at standard centres (typically 400mm or 600mm), ensuring plumb and level installation. For external walls, ensure appropriate insulation and weather protection are incorporated into the design.
- Suitable for internal partition walls and external stud walls
- Superior strength provides enhanced stability
- Fix at standard centres between sole and head plates
- Ensure plumb installation for structural integrity
Roof battens and structural support
The 47 × 125mm section can be used for roof battens and structural support in roof construction. Its strength grade and treated protection make it suitable for both traditional and modern roof designs. Ensure adequate fixing to rafters or trusses, and allow for proper ventilation in the roof space.
- Suitable for roof battens and structural support
- Treated protection extends service life in exposed roof environments
- Fix securely to rafters or trusses
- Maintain adequate ventilation in roof spaces
Decking frames and outdoor construction
The pressure-treatment makes this timber suitable for decking frames and outdoor structural applications. It resists rot and insect attack, providing long-term durability in exposed conditions. Ensure all fixings are corrosion-resistant and that the structure allows for adequate drainage and ventilation to prevent moisture retention.
- Pressure-treated for protection against rot and decay
- Suitable for decking frames and outdoor structures
- Use corrosion-resistant fixings in outdoor applications
- Ensure adequate drainage and ventilation around the structure
General construction and building work
Beyond specific applications, C24 Carcassing Timber is a reliable choice for general structural timberwork. Its consistent quality, strength grading, and treated protection make it suitable for a variety of building projects. Always refer to relevant Building Regulations and structural design standards when determining suitability for your specific application.
- Strength-graded to C24 for reliable load-bearing performance
- Consistent quality and fewer knots than lower grades
- Suitable for both indoor and outdoor applications
- Meets BS EN standards for structural timberwork
