Insulating structure

Claim 1

An insulating structure having a plurality of modules for installation adjacent an associated structural surface, and a plurality of associated parallel supporting members, each of said supporting members extending at right angles from said structural surface, each module extending from two adjacent supporting members, each module being disposed in side by side relation to at least one other module, each of said modules comprising: first and second sidewalls in spaced substantially parallel relationship, each having inner and outer edges; said first sidewall including a tab strip along its said inner edge foldable outwardly upon itself for connection of said inner edge of the first supporting structure adjacent the structural surface after the inner edge of said second sidewall has been connected adjacent the structural surface, said tab strip being formed from a portion of said first sidewall, and being defined by fold-enabling means, said first and second sidewalls being dimensioned and configured to depend from respective facing surfaces of the first and second parallel supporting surfaces; a plurality of reflective foil sheets connected to the first and second sidewalls, said foil sheets being oriented in mutually spaced substantially parallel relationship to extend (1) intermediate and (2) generally at right angles to said first and second sidewalls, the majority of said plurality of reflective foil sheets being disposed at a lower elevation than the lowest elevation of the first and second parallel supporting structures; and one of said first and second sidewalls including a tensioning member along the outer edge thereof, each of said modules being attached by one of said tensioning members to at least one adjacent module at their respective outer side wall edges with their respective outer sidewalls in spaced relationship from said supporting structure and said supporting members to define an air space adjacent to the lowermost face of the supporting members.
