All Capping is fully pressure treated. Each cap has a 2 Way Weather point (2WW on the peak of the cap) We supply Flat or Moulded Capping. Flat is the bottom of the cap to sit on top of Featheredge boarding or panels. Moulded capping is a rebated cap, with a 2WW top. The rebate allows the cap to sit around the Featheredge boarding.
