Thermally insulating panels are formed at opposite sides with finishing edge strips about which sheet metal facings of the panels engage, the strips having ribs and grooves to allow mortise and tenon interconnection of the panels. A fold between a groove and a rib of the respective panel receives a metal insert which provides structural support and interengaging flanges of the insert, which preferably is composed of high density PVC, can interlock for effective sealing.

A profile member adapted to form an edge of an insulating panel for coupling with an identical but inversely positioned coupling member of an adjoining insulating panel, said profile member being generally of S transverse cross section and being formed unitarily with: a rib lying parallel to a groove so that said rib is engageable in the groove of the other profile member and the groove receives a rib of the other profile member, and a fold of flattened rectangular cross section adapted to extend inwardly with respect to a panel formed with the profile member and opening toward the other profile member for receiving a flat rectangular-section metal insert so that said fold is closed when the profile member is interfitted with the other profile member, said fold being formed at a base thereof with a pair of oppositely projecting flanges engageable in a body of foam material adapted to be molded around said fold, said rib being bounded on a lateral side of said profile member with a flange formed with a laterally outwardly open fold adapted to receive a right angle bent edge of a sheet metal facing of a panel formed with the profile member, said groove being bounded by a lateral flange cooperating witht he lateral flange of the other profile member bounding the rib thereof to form a groove into which an edge of a sheet metal facing bent around the lateral flange bounding the groove through 180°can extend, the lateral flange bounding said groove being formed with at least one lip projecting toward a base of said groove and engageable with an array of teeth formed on a lateral flange of the other profile member bounding the rib thereof to enable interlocking of said profile members.
