<p>Membranous thermal barrier and means for its placement on and removal from an ice surface, such as a rink. The barrier comprises a flexible, sheet-like covering (29) having low moisture permeability and thermal insulation properties sufficient to substantially reduce heat transfer to the ice surface when emplaced on the ice during non-use hours. Reel means (10) are provided to wind, transport, store and dispense the covering quickly and with minimal labor. </p> |
