Abstract

A sandwich structure as described, wherein a core of foamed plastic is enclosed between surface layers 7, of a hard, wear-resistant material 8. The core material consists of small units 5, 6 of a foamed plastic, each unit being totally enclosed by an integral, moisture tight plastic skin. The units are in the form of flat blocks, and when placed edge against edge, they form a substantially unbroke surface. The units which may be of polyurethane may be fibre-reinforced, suitable surface layers being of metal, plastics or plywood. <IMAGE>
