Treated Carcassing

Treated Carcassing

Lawsons Treated Carcassing timber has been processed to be used under structural applications such as floor joists, studwork and roofing applications. As this timber has been kiln dried (KD), a process where the timber is dried to a specific moisture content, it will be stronger and more stable. Being regularised means it is planed to a specific size rather than being planed to a smooth finish so some areas may have a slight roughness. The grading (C16) is most commonly used and is an assessment of structural strength so will have less splits and knots, especially at the edges. The following timbers have been treated against rot with copper based preservative at high pressure to comply with BS8417 UC2.
