ABSTRACT:
In a one step process a body of woodchips or lignocellulosic fibres impregnated with a heat curable polar resin adhesive is contacted with EP(D)M rubber sheet containing peroxide curative and subjected to hot pressing. The rubber is thereby cured and caused to convulcanize and adhere to the woodchips to produce a weather resistant construction element.
