An insulating container (50) and a method of manufacturing it comprises providing a sidewall blank (12B) having two sections separated by a fold sco re (15), and a separate insulating sheet (18) (corrugated, ribbed, embossed, foamed, perforated, etc.) adhesively fastened to one of the sections. Adhesi ve is applied to an area (12) adjacent the fold score bonding two sections adjacent the folded score. The assembly is wrapped around a mandrel to bring the outer edges together at a side seam (22S) which is sealed to form a sidewall (12). In a second embodiment, the insulating layer can be a coating on one or both of the sections of the two-section starting blank. In a third embodiment, the insulating section (40) can be integral with, and extend fro m, one edge of the starting blank. It is folded over first to form the middle layer of the wrappable assembly.
