Abstract
A load bearing, thermally insulating panel for use to cover an ice surface is made up of a plurality of modular, polymeric floor members having a structural dense body structure and a flat upper wall over which a vehicle can travel. Each floor member has an undersurface with integral, downwardly projecting, load distributing, support pillars within a floor member-surrounding, downwardly projecting marginal wall. A polymeric foam insulative layer of substantially lesser density than said floor member and substantially lesser thermal conductivity is molded within the floor member surface surrounding the pillars to fill the space around the pillars and the space between the pillars and marginal wall.
