In some instances a hardwood can be used in the core, but usually a lower density species is chosen to keep the weight down while adding strength with a tougher hardwood.Īn issue with lumber core plywood is the variability that can be found in the core itself. As such Blockboard is used a great deal in the marine and aerospace industries where weight is a chief concern. In furniture an added advantage is when routed edge treatments are necessary and the edges cannot be concealed.Īdditionally since lumber core plywood (also known as Blockboard in much of Europe) uses primarily softwood lumber for the core, it is substantially lighter than veneer core plywood or MDF. Bookcases and shelves are the perfect example for using a lumber core plywood. The advantage and primary reason to use a lumber core plywood is stiffness over longer lengths. Unlike the thin veneers, the individual staves or battens in this core are much thicker, usually 2/3 the total panel thickness. Two face veneers are used, one cross grain to tie together the core and prevent any telegraphing of the individual boards in the core to the face. ![]() This plywood consists of thicker strips of hardwood, usually Basswood, glued up into a larger panel then face veneered. These high density cores are the creme de la creme of veneer cores as well as the most expensive. ![]() Maple ply is also often known as Apple Ply. This plywood is often used when the edges will be exposed in the final product and decorative in nature. The edge strength is very high and less prone to splintering like Fir and Poplar while also being very attractive. There are no voids with this type of core. Both species are much harder, and the thinner, more abundant layers make an extremely stable product.
