What is blockboard?

: a plywood board in which veneer layers used in the core are replaced by blocks of wood, the direction of grain of the blocks running at right angles to that of the adjacent veneer.

What are the uses of blockboard?

But in contrast to chipboard, blockboard has great structural stability and strength and is suited to applications such as doors, shelves, tables, panelling, partitions or kitchen worktops which have no intermediate supports.

Is Blockboard better than plywood?

Blockboard is more prone to water damage as it is known to retain moisture. It is stiffer than plywood and less prone to bending. It is dimensionally stable, and can withstand cracking. Unlike plywood it does not split on cutting, and is easy to work with.

How strong is blockboard?

Block boards have good screw strength and high strength, It can also hold screws and nails very well as compared to particle board and MDF. Compared to other engineered wood products such as Particle boards and MDF, block board is comparatively stronger and lasts longer.

What is plywood blocking?

Blocking (dwang, nog, noggin, and nogging) is the use of short pieces of dimensional lumber in wood framed construction to brace longer members or to provide grounds for fixings.

How do you cut a blockboard?

Use a circular saw. These are used for cutting timber, MDF, block board and ply board. It makes direct line cuts. Like with a jigsaw, the actual cut is done as the cutting blades rise up-wards through the timber, so the neatest side will be on the underneath.
