Hardboard is produced by pressing natural wood fibres under high pressure and temperature. Due to unique, wet production technology one side of the panel is smooth, other has wiremesh imprints. Since there is no chemical adhesives and/or additives used in production of hardboard, formaldehyde content is as much as natural wood contains. Hardboard is used in construction, furniture production, as packing material for fruits and vegetable, toys production, door production, etc.
