    Abstract: The invention relates to materials containing lignocellulose that have a core and two covering layers, containing and preferably consisting of, in said core: A) 30 to 98 wt.% of lignocellulose particles, B) 0 to 25 wt.% of expanded plastic particles with a bulk density in the range of 10 to 150 kg/m3, C) 1 to 50 wt.% of one or more binders selected from the group consisting of aminoplast resin, phenol formaldehyde resin, and organic isocyanate with at least two isocyanate groups, and D) 0 to 10 wt.% of additives, and, in said covering layers: E) 70 to 99 wt.% of lignocellulose-containing particles, fibres, or mixtures thereof, F) 1 to 30 wt.% of one or more binders selected from the group consisting of aminoplast resin, phenol formaldehyde resin and organic isocyanate with at least two isocyanate groups, and G) 0 to 10 wt.% of additives; with 2 to 30% of the lignocellulose particles A) being replaced with treated cellulose materials, treated natural fibres, synthetic fibres or mixtures thereof. The invention also relates to the production and use of same.
