Abstract:
1. A heat insulator for a roof structure comprising: an elongated first sheet having a predetermined length, opposed side edges, a predetermined width between said opposed side edges, and an intermediate portion between said side edges, an elongated flexible second sheet having a length greater than said predetermined length of said first sheet, side edges, a width between its said side edges greater than said predetermined width of said first sheet, and an intermediate portion between said side edges, said second sheet positioned in superposed relationship with respect to said first sheet and with the lengths of said sheets parallel and the length of said second sheet extended to the same length of said first sheet, and said oppossed side edges of said second sheet aligned with and connected to said opposed side edges of said first sheet, whereby said heat insulator can be stored in a reel with the second sheet collapsed against the first sheet, and when said heat insulator is unreeled, the second sheet is positioned below said first sheet and said sheets are suspended by their opposed side edges with said first sheet not folded, gravity tends to move said intermediate portion of said second sheet away from said intermediate portion of said first sheet to form an air space between said intermediate portions of said sheets, and said second sheet has enough additional length with respect to said first sheet to form folds across its length about structures in the roof, and at least one of said first or second sheets bearing a heat reflective surface facing the other of said first or second sheets.
