An elongated insulating structure, for installation adjacent a structural surface having supporting structures extending at right angles therefrom, including first and second sidewalls orientated in spaced mutually parallel relationship. Each of the sidewalls has an inner edge and an outer edge and first and second oppositely disposed ends. The first side wall includes a tab strip along the inner edge thereof which is foldable outwardly upon itself to enable connection of the inner edge of the first supporting structure to the associated first supporting structure adjacent the structural surface after connection of the inner edge of the second associated supporting structure adjacent the structural surface. A plurality of reflective foil sheets extend intermediate the first and second sidewalls. In another form of the invention which is particularly suitable for use in insulating roofs, the sidewalls of the insulating structure depend from the structural members, such as the rafters.
