How and where to use guide
4.8Mtr X 47 X 125mm C24 Treated Regularised KD Carcassing Timber
Floor joists and suspended floors
This timber is commonly used for floor joists in residential properties. The 47 × 125mm section is suitable for standard residential floor spans when properly spaced and supported. Joists should be spaced at 400mm or 600mm centres depending on load requirements and span. Ensure adequate bearing on walls or beams, and provide lateral bracing to prevent twisting.
- Standard section for residential floor construction
- Typical spacing: 400mm or 600mm centres
- Requires adequate bearing and lateral bracing
Stud walls and partitions
C24 timber is well-suited for stud wall construction in both load-bearing and non-load-bearing applications. The regularised finish provides a clean, professional appearance and makes installation straightforward. Studs are typically spaced at 400mm or 600mm centres and should be properly braced and fixed to top and bottom plates.
- Suitable for load-bearing and non-load-bearing stud walls
- Regularised finish aids installation and appearance
- Standard spacing: 400mm or 600mm centres
Roof battens and roof structures
This timber can be used for roof battens, purlins, and other roof structural elements. The pressure treatment provides protection in the roof environment where moisture and temperature fluctuations occur. Ensure proper ventilation and avoid trapping moisture between the timber and roof covering.
- Suitable for roof battens and structural elements
- Pressure treatment protects against moisture exposure
- Ensure adequate ventilation in roof spaces
Decking frames and outdoor structures
The pressure treatment makes this timber suitable for outdoor applications such as decking frames, garden structures, and external cladding frames. The treatment protects against rot and insect attack in exposed conditions. Ensure adequate drainage and ventilation around outdoor timber to maximise durability.
- Pressure treatment suitable for outdoor exposure
- Use for decking frames and garden structures
- Ensure good drainage and ventilation
General construction and framing
Beyond specific applications, C24 Treated Carcassing Timber is a reliable choice for general structural framing, bracing, and support work. Its strength grading and treatment make it suitable for applications where durability and load-bearing capacity are important. Always follow building regulations and structural design specifications for your specific project.
- Suitable for general structural framing and bracing
- Reliable for both indoor and outdoor projects
- Always follow building regulations and design specifications
