Hardboard is a high density and high strength panel is formed with wood fibres and under high temperatures an high pressure compression during a pressing process the degree of pressing involved leads to the high density and hardness, hence the panel’s name. Heat and steam is applied to leave fine, fluffy brown fibres. These fibres are transformed into mats, which are held together with lignum and other glues.
The tempering of the boards achieve great physical and mechanical characteristics and excellent dimensional stability. Hardboard cannot be used outside or in wet applications because it absorbs water.
