These profiles are recognised as superior structural timber by trade and commercial scale contractors and haves a higher level of grading – C16/24. For amazing, consistent quality for frames and studding, choose our CLS stud timber that can be both sawn and tanalised to suit your requirements.

Additional Information

CLS stud profiles can be used with plasterboard and when skimmed will finish at 94mm, the same as the size of a standard door lining – which we also sell! If you intend to use CLS stud timber for exterior projects, ensure you select your sizes as treated, so they withstand and are resistant to moisture, insects and fungi growth. 


  • Use untreated CLS outdoors as long as it’s fully sealed or painted with appropriate treatment 
  • Treated CLS stud timber is your go-to for building shed frames and flooring thanks to its straight edge and density 
  • Utilise for interior framing and partitioning, including walls, doorways and windows 
  • Ideal for roof and floor joists or any carcassing application
