ABSTRACT:
A thermal barrier device provides a heat insulative cover having low to negligible permeability to water vapor and a remote controlled reeling and unreeling mechanism for deploying and harvesting the cover onto and off of the exposed surfaces of ice rinks, curling rinks, ski jumps, toboggan runs, and the like. The length and width required for covering a particular exposed surface is readily adjustable by lengthwise and edgewise coupling means.
