Hardboard

Hardboard is similar to particle board and medium-density fiberboard, but is denser, stronger and harder because it is made out of exploded wood fibers that have been highly compressed.

In Europe today, the same type of fibreboard product generated by the wet process, is named as Natural Fibre Board, and this is a registered trademark.

In the early 1920s, improved methods of compressing wet wood pulp at high temperatures resulted in a higher density product.

It is used in construction, flooring, furniture, home appliances, automobiles and cabinetry, and is popular among acrylic and oil painters as a painting surface due to its economical price (though it must be coated with gesso or canvas before use).

Hardboard has become less popular in the construction industry in recent years due to new environmental targets[11] to procure more sustainable temporary protection materials.
