3.6Mtr X 47 X 75mm C24 Treated Regularised KD Carcassing Timber
Typical applications
This timber is ideal for floor joists, roof battens, stud walls, decking frames, and general structural construction work. The C24 grade provides enhanced strength and stability compared to lower grades, making it suitable for applications requiring reliable load-bearing performance. The pressure treatment extends its lifespan in both indoor and outdoor environments.
- Floor joists and joist systems
- Roof battens and roof framing
- Stud walls and partition framing
- Decking frames and outdoor structures
- General structural timberwork
Indoor applications
For indoor use, C24 timber is suitable for floor joists, ceiling joists, stud walls, and internal framing. The regularised, planed finish provides a clean appearance and makes installation straightforward. The kiln-dried condition helps minimise movement and warping once installed. The treatment provides protection against moisture-related decay if the timber is exposed to occasional damp conditions.
- Floor joists in residential and commercial buildings
- Ceiling joists and roof framing
- Internal stud walls and partition frames
- Loft and attic framing
Outdoor and exposed applications
The pressure treatment makes this timber suitable for outdoor use where it may be exposed to weather or damp conditions. It is suitable for decking frames, garden structures, and external framing where durability is essential. The treatment protects against rot, fungal decay, and insect attack, extending the timber's lifespan in exposed environments.
- Decking frames and outdoor platforms
- Garden structures and pergolas
- External framing and cladding battens
- Exposed structural applications
Installation and finishing
The regularised finish means the timber is smooth and planed, making it easy to handle and install. It can be fixed using standard fixings such as nails, screws, or bolts depending on your application. The timber can be painted, stained, or left natural. Always ensure fixings are appropriate for the load and application, and follow your structural design or building plans for spacing and installation details.
