Pioneer Millworks Accoya® Color Grey Siding is a high performance, ultra-low maintenance product with impeccable sustainability credentials. Made exclusively with FSC® certified Radiata Pine, the wood goes through a proprietary acetylation process which results in an extremely stable and rot resistant siding product backed by a 50-year residential above-ground warranty. Accoya Color Grey Siding is also impregnated with a dye that penetrates the wood to the core with pigment. This means that after an initial coat of clear sealer, this is a once and done install with a lifetime free refinishing and costly maintenance.
