ABSTRACT:
In order to prevent the build-up of static electricity in laminated cork floor tiles consisting of a layer of granular cork bonded by a binder and a wear surface preferably composed of polyvinyl chloride foil, provided on one side of the granular layer, the electrical conductivity of the laminate is increased by incorporating agents to reduce electrical resistance in the binder included in the cork layer and by incorporating antistatic agents in the wear surface. The tiles may have a moisture barrier provided on the side of the granular cork layer opposite the wear surface, the moisture barrier also incorporating an agent or agents reducing the electrical resistance thereof.
