Abstract:
An insulation system for outdoor ice rink comprising:an insulating sidewall; the sidewall having insulating means; the sidewall continuously surrounding an ice sheet and being in close proximity to the peripheral edge of the ice sheet, the sidewall extending generally vertically upwards from a level below the lower surface of the ice sheet to a level higher than the upper surface of the ice sheet; the sidewall having a free, generally flat, horizontal, upper surface;a removable insulating cover; the cover having insulating means; the cover having an upper surface, the upper surface of the cover being nominally flat and painted to a color offering high reflectivity to radiant energy incident on the cover from the ambient; the cover being constructed to have such dimensions that it can rest upon the free, generally flat, horizontal, upper surface of the sidewall and thereupon define, in conjunction with the sidewall, a generally closed space above the surface of the ice sheet;the sidewall, in combination with the cover resting upon the sidewall, providing such degree of insulation to the ice sheet, as to enable the continuance of the ice sheet at ambient temperatures typical of the summer season.
