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.

[ I claim:] [1.] An ice cover panel for use in covering an ice surface which achieves a balance between strength in compression and thermal insulative factor, comprising:(a) a polymeric floor member having a dense structural body structure defined by a substantially flat upper wall surface over which a vehicle can travel and an undersurface;(b) said floor member undersurface having integral, downwardly projecting load distributing, discrete support pillars extending below said undersurface within a floor member-surrounding, downwardly projecting marginal wall extending below said undersurface, said floor member being formed with space surrounding said pillars and space between said pillars and marginal wall; and(c) a polymeric foam insulative layer of substantially lesser density than said floor member, flowed into said spaces and cured within the floor member marginal wall, to substantially fill the space around said pillars and the space between said pillars and marginal wall and adhere to said pillars and marginal wall.
