Block Board

Block Board 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.

Block Board panels are produced in 3-5 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.
