 Hardboard is a cheaper option than plywood where strength is not required, and will need supporting with a timber frame. It is a hard, dense sheet material made of compressed softwood fiber pulp bonded together with resin glues under heat and pressure.
The quality of the board depends largely upon the density of the fibers, and has many applications.
There are three types of hardboard available, standard, medium and oil-tempered. Oil tempered boards are impregnated with oil making them stiffer, harder and more resistant to scratches and moisture.
Hardboard is made in standard sheet sizes of 2440mm x 1220 mm, at a thickness range from 3mm to 9mm, though smaller sheets are now available in DIY stores. Hardboard is quite flexible, but can be brittle and should be handled with care especially at the corners and edges.
