CETRIS is the largest manufacturer of cement-bonded wood particle boards in Europe. These wood-cement panels combine the advantages of both materials. They are lighter than traditional cement or concrete panels and are reinforced by wood particles. They are naturally resistant to humidity, frost and mold, even outdoors and in contact with the ground. They are also non-combustible (classification A2,s1-d0 equivalent to M0). The uses are therefore numerous: interior cladding and exterior facades, bases, floors, concrete formwork, acoustic slabs, layout, fire protection, etc.
