How and where to use guide
4.2Mtr X 47 X 75mm (3" x 2") C24 Treated Regularised KD Carcassing Timber
Structural applications
C24 timber is ideal for load-bearing structural work. Its strength grade makes it suitable for applications requiring higher load capacity than C16 timber. Common structural uses include floor joists supporting residential loads, roof battens and rafters, and stud walls for internal partitions and external walls.
- Floor joists for ground and upper floors
- Roof battens and rafter support
- Stud walls and partition framing
- Structural bracing and support members
Outdoor and damp environments
The pressure-treatment provides protection against rot and decay, making this timber suitable for outdoor construction and areas with moisture exposure. It is commonly used for decking frames, garden structures, and external building work where untreated timber would deteriorate.
- Decking frames and substructures
- Garden structures and pergolas
- External wall framing
- Ground-floor joists and damp-prone locations
Indoor applications
Treated carcassing timber is equally suitable for internal structural work. Its smooth, planed finish provides a clean appearance, and the treatment offers protection against fungal growth in areas prone to condensation or high humidity, such as kitchens and bathrooms.
- Internal floor joists
- Stud walls and internal partitions
- Loft framing and storage structures
- Areas with high humidity or condensation risk
