Birch Plywood is constructed using solid birch veneers and then overlaid with a quality birch face veneer on either side. It is widely used in joinery and furniture making as it has a clean, bright appearance which is aesthetically pleasing.
As it is birch and has a construction of the board it is very strong but also light and easily machined.
Plywood is graded with a face and back grade designation:
B/BB: Single piece face and back veneer. Face veneers are considered clear and free of defects with a light-uniform color. Back allows 3-6 color matched patches, which are oval in shape and egg sized. Inner cores are solid birch single piece veneers.
BB/BB: Single piece face and back. Both face and back veneers allow 3-6 small color-matched patches on average and some light mineral streaks. Tight pin knots may be present. Inner cores are solid single piece veneers.
BB/CP: Single piece face and back. The “CP” back veneers are downgraded from “BB” grade veneers, which allow for unlimited patches and sound knots, but does not allow for open defects. Inner cores are solid birch single piece veneers.
CP/CP: Single piece face and back. Face and back grade veneers allow unlimited sound knots and repaired splits and unlimited patches. The panel is sound both sides and designed for laminating.
C/C: Patches, open knots, and small veneer splits allowed. Veneer lap and small core voids permitted. This panel is not sanded and would be used for structural purposes.
