Blockboard is an engineered wood that consists of a core made from softwood strips, these strips are positioned edge to edge and are sandwiched between two veneers of hardwood. This composition is then glued in place under pressure. Blockboard lends itself to indoor use for such items as shelves, doors, panelling and furniture. It is not designed to be exposed to the elements, so it is not recommended for outdoor use. The edges of blockboard can be given veneers for an attractive finish.
Lighter than other boards such as plywood, making transport and assembly easier. Blockboard is also cheaper than plywood. Due to the lines of the grain in the central blocks, blockboard has good compressive strength, making it stiff and useful in the construction of long furniture, shelves and panelling.
Blockboard is also strong in humid conditions and is resistant to warping, an area where resin based boards such as chipboard are lacking. Blockboard is also very good at holding nails and screws.
