BLOCK BOARD

Blockboard is a wood based panel, made up of a core of softwood strips glued together. The strips may be up to about 28mm wide and are placed edge to edge and sandwiched between veneers of softwood, hardwood or thin MDF or particleboard, glued under high pressure.

The internal strips are generally made of either hardwood, Silverwood or Pinewood.

Blockboard is used to make doors, tables, shelves, paneling and partition walls. It is normally used for interior usages, due to the type of glues used. To achieve maximum strength, it is important to ensure that the core runs lengthways. Blockboard (also called lumber core) has very good screw holding and can be considered as solid wood; it has a good resistance to warping.

Blockboard panels are produced in 3-layers, with one veneer sheet (or thin MDF or particle board) covering each side, or 5-layers with two veneer sheets per side for better stability.

Most common sizes in blockboard are: 8X4, 8X3, 7X4, 7X3, 6X4, 6X3, 5X4, 5X3. Available thicknesses are between 19mm and 45mm.

Blockboard may be purchased with a variety of applied finishes such as wood veneers, melamine paper and plastic laminate surfaces.
