An insulating batt having two sheets of heat reflective insulating material and connecting means between and connecting sheets together in an overlapping substantially parallel relationship. The connecting means includes a plurality of bracing strips extending between and connected to each of sheets. The bracing strips enable the batt to be adjusted between a collapsed position in which the sheets are closely adjacent, and an operative position in which sheets are mutually spaced. Each bracing strip has two substantially parallel longitudinal fold lines that a bracing web is defined between lines and a respective side margin extends from the web beyond each line. The respective margin of each bracing strip is secured to each of sheets such that the bracing strip web is substantially normal to and defines the spacing between the sheets when batt is in its operative position and such that, moving the batt to its collapsed position, the webs are substantially parallel to sheets. Each of a plurality of partition strips extend longitudinally between the webs of bracing strips. Each partition strip is folded along two substantially parallel fold lines such that a central partition web is defined between the lines and a respective side flange extends from the web beyond each of its lines. Each bracing strip has a respective flange secured to each of webs of successive bracing strips, with the width of each web substantially corresponding to the spacing between its bracing strips when the batt is in its operative position.

An insulating batt comprising two sheets of heat reflective insulating material, and connecting means provided between said sheets and connecting said sheets together in an overlapping, substantially parallel relationship; said connecting means enabling said batt to be adjusted between a collapsed position in which said sheets are closely adjacent, and an operative position in which said sheets are spaced from each other by said connecting means; wherein, said connecting means comprises: (a) a plurality of substantially parallel, mutually spaced bracing strips extending between and connected to each of said sheets, each bracing strip having two substantially parallel longitudinal fold lines such that a bracing web is defined between said lines and a respective side margin extends from the bracing web beyond each fold line, each bracing strips having a respective side margin secured to each of said sheets such that the bracing web is substantially normal to and defines the spacing between the sheets when said batt is in its operative position and such that, on movement of the batt to its collapsed position, the bracing webs are substantially parallel to the sheets; and (b) a plurality of partition strips of heat reflective insulating material, each of which extends longitudinally between the webs of successive bracing strips, each partition strip being folded along two substantially parallel fold lines such that a central partition web is defined between said fold lines and a respective side flange extends from the partition web beyond each of its fold lines, each partition strips having a respective side flange secured to each of the webs of said successive bracing strips, the width of the partition web substantially corresponding to the spacing between said successive bracing strips when said batt is in its operative position such that, on movement of the batt from its collapsed position to its operative position, each partition web is spaced from each of the sheets.
