Duncan62 Posted November 13 Share Posted November 13 Help please! I have spec'd open face cladding - what USE CLASS specification should the batten and cross battens be? I am concerned I require UC3 treated wood (pressure treated to push preservative into the wood), and not UC2 which is easily available (green treated timber that is dipped, not pressure treated. i.e. roofing battens). Because open cladding means the battens will be subject to constant moisture - I think UC3 should be spec'd? Correct? Further info: https://www.jamesjones.co.uk/assets/uploads/files/treatment/tanalith-e-suppliers-guide.pdf Then we can get into actually finding this UC3 wood in sized like 25x50mm, 50x50mm or 50x100mm, I cant find it anywhere.

Duncan62 Posted yesterday at 13:16 Author Share Posted yesterday at 13:16 Appreciate that. And I agree. Finding it in non fencing sizes is not easy however. Also about 4x the cost. Pragmatism won out. UC2 used. End grain sealer on cut ends. DPM paint on top of the horizontal surfaces. Link to comment Share on other sites More sharing options...
