for interiorfor exterior fittingspine

Solid single layer wood board made up of pieces of wood (strips) glued together edge to edge and or on edge based on an aqueous dispersion-based adhesive of polyvinyl acetate. The manufacturing process is completed by longitudinal cut of the piece to normalized length in addition to the item’s sanding. The international term that used is the acronym SWP (S = solid; W = wood; P = panel). B/B Grade: both faces have live knots (not dead ones), that in no case will result in breakage or cracking of the strips.
