abstract Lignocellulosic boards are one of the most popular materials widely used in the building industry for outfitting (furniture) and for interior decorating (wall and ceiling panelling). This type of boards possesses considerable advantages such as high mechanical strength, thermal insulation properties and possibility of different type of finishing application. Due to their unfavourable behaviour under fire conditions however their use has often been limited particularly in tall and public buildings. Investigation of the Institute of Natural Fibres concerning the flame-retardant particleboard’s with application both organic and mineral binders and mineral geopolymers were carried. Technology of three-layer composite board manufacturing in which the inner layer is made of lignocellulosic particles while the outer layers of expended vermiculite as fire barrier was developed. The surface finishing of these composite boards can be made by covering them by veneer, foils (Al), laminates, paints and intumescent fire barrier. The influence of different ratio of the mineral particles to the lignocellulosic particles and different fractions (granulation’s) both natural and expanded vermiculite on flammability and physic-mechanical properties of one- and three-layer particleboard are presented.
