Our 22ex mm 150mm Pressure Treated Green, feather edge boards are mostly used by our customers to build closeboard fencing.
We have these @ 2.4m which makes them ideal cladding your shed, log store, bike shed & many more items 
The term feather edge refers to the shape of the board. Each one starts out as a single 22mm thick board which is why we list them as EX 22mm. This is then machine cut diagonally to make two feather edge boards - each with a taper from thick (approx. 15mm) to thin (approx. 6mm).
