Blockboard

Blockboard

Picture
Blockboard is a wood based panel, made up of a core of vertical grain spruce glued together. The strips may be up to about 40mm wide and are placed edge to edge and sandwiched between veneers of poplar, hardwood or thin MDF glued under high pressure.
The internal strips are generally made of light weight vertical grain spruce.

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 3-5 layers, with one veneer sheet (or thin MDF or particlebaord) covering each side, or 5-layers with two veneer sheets per side for better stability.
