Multi-layer woodboard

Multi-layer wood board, multi-layer panels or simply multi-layer board can refer to a variety of engineered wood products, depending on location and the manufacturer. However in general it is a board product made up of 3 or more 3 layers of material, with each layer often being solid wood and slightly thicker than that found in plywood, normally around 3-6mm and the layer can vary in thickness. The term may however be used to refer to any type of engineered and layered board product, it might also be used to refer to a thick type plywood board that has more than five layers at the same thickness, although this is often called multiplex board.

In general multi-layer wood boards are normally timber-based sheet materials that comprise of multiple layers of similar thickness timber, glued under high pressure, with the grain of each layer laid at 90 degrees to the previous. The wooden layers tend to be solid wood, although because they are relatively thick (in comparison to plywood or veneers) a few examples of such products might comprise of layered composite wood products.

[edit] Uses

In general multi-layer board is slightly stronger than similar products such as blockboard, coreboard or laminboard and as such can be used in flooring solutions and general construction. It is also used in furniture production, indoor wall cladding and so on, normally mostly interior use due to the specification of glues.

[edit] Working

Multi-layer board can be worked with standard tools, easily sawn, good screw and nail-holding properties, and because of its greater improved rigidity and strength, has some spanning capability, such as between joists. It is not as strong or hard wearing as multiple layer plywood products (multiplex) because it tends to be softwood based, with thicker layers, therefore less dense and with less glue, it does however tend to be lighter.
