Fixing and buying guide
3.0Mtr X 47 X 100mm (4" x 2") C24 Treated Regularised KD Carcassing Timber
Selecting the right size
This product is supplied as 3.0 metre lengths with a finished section of 47 × 100mm. C24 timber is suitable for floor joists, roof battens, stud walls, and decking frames. Consider your span requirements and load conditions when determining whether this section is appropriate for your application. C24 offers enhanced strength and stability compared to C16 grade timber, with fewer knots and improved load-bearing capacity.
- 47 × 100mm section is commonly used for stud walls and lighter structural applications
- 3.0 metre length suits standard wall heights and joist runs
- C24 grade provides superior performance for demanding structural work
- Regularised finish means consistent, planed dimensions for easier fitting
Pressure treatment and durability
This timber is pressure-treated with preservative to protect against rot, fungal decay, and insect infestation. The treatment provides long-term durability, making it suitable for both internal and external applications. Treated timber is particularly valuable in damp environments or where moisture exposure is likely.
- Preservative treatment protects against rot and fungal decay
- Resistant to insect attack, including woodworm and termites
- Suitable for outdoor construction and exposed locations
- Treatment extends service life significantly compared to untreated timber
Storage and handling
Store treated carcassing timber in a dry location, protected from ground contact and excessive moisture. Stack timber with spacers to allow air circulation and prevent moisture trapping. Handle carefully to avoid damage to the planed finish, which aids installation and appearance.
- Keep off the ground using bearers or pallets
- Protect from prolonged wet weather during storage
- Use spacers between layers to allow ventilation
- Handle with care to preserve the regularised finish
Compliance and standards
This C24 Treated Carcassing Timber meets current BS EN standards for structural timber. Strength grading to C24 ensures the timber meets defined load-bearing requirements for structural applications. Always verify that the grade and size selected are appropriate for your specific structural design.
- Strength-graded to C24 standards
- Meets current BS EN requirements
- Suitable for structural applications requiring defined load capacity
- Verify suitability with structural design calculations where required
