ABSTRACT:
An insulation panel having back and front faces spaced apart parallel to each other. A female edge has a recessed region along part of its length and a male edge has a complementary shape to the recessed region of the female edge so as to closely fit within the female edge of an adjacent similar insulation panel. A web extends across the distance separating the back and the front faces, the web being formed integrally with one of the faces. The female edge is generally channel shaped and has a base wall being defined by the web, the front wall comprising an edge portion of the front face which is turned inwardly towards the back face and then turned back upon itself to define a double thickness front wall of the channel shape, the edge portion of the front face turning to extend towards the back face so as to define the web. The male edge is also channel shaped but is stepped in so as to define a narrower width channel shape to fit within the female edge channel shape. The web at the female edge and the base wall at the male edge are integral with the front face of the panel, the back face of the panel being provided with edge portions which are turned in and towards the front face and then turned back on themselves to receive therein the edges of the front face which are themselves finally turned outwardly to form the outer walls of the female edge and male edge channel shapes.
