This is Baltic birch-veneered plywood. It is suitable for interior cabinetry applications. Sheet size is 5 feet by 5 feet. The appearance is rotary-cut (the veneers are cut from the log in a spiral). The core is veneer, which is structurally stronger than an MDF, or particle board, core.
Update: 10/7/21 We are experiencing difficulty sourcing Baltic Birch Plywood. We have been able to bring in 6mm, 12mm and 18mm as reflected in our pricing. Please note that some of this new stock is one grade down from the top grade that we usually stock.
Some of the new 12mm and 18mm stock is a BB/BB grade which allows for some plugs. In what we have seen so far most sheets have plugs on one or both sides.
We are still unable to source the 3mm and 9mm Baltic Birch in the wholesale markets.
