ABSTRACT "A SANDWICH PANEL" A rectangular sandwich panel comprises two skins with an insulating material, such as foam, sandwiched therebetween. Two spaced apart arms form a double tongue on each of two adjacent circumferential edges of the panel and a cooperable double groove is formed along the other two adjacent circumferential edges, whereby, without additional coupling means, the panel can be assembled on all sides by a tongue and groove connection with adjoining panels. At the corner point of the panel, where double tongues are adapted to meet double tongues of adjoining panels, part of the arms of the double tongues are cranked so that the spacing between the arms forming the double tongues is increased by at least the thickness of the arms, to accommodate arm parts of double tongues of an adjoining panel when assembled together.
