Panel siding for the wall of a building comprising elongated panels arranged in close, parallel relationship with the longitudinal edges of adjacent panels opposed to one another. The panels have integral tongue and groove formations along the opposed longitudinal edges which are interengaged to provide connections between panels. A layer of insulation is provided at the rear of each panel, providing a panel insulation unit. Each panel insulation unit is installed in a single step.

A panel system useful for side walls and the like comprising: a plurality of elongated plastic panels, each said panel having being made of a relatively thin strip which is relatively stiff, each said panel having parallel longitudinal edges, each said panel having a front wall and a rearwardly turned first wall extending laterally away from one edge of said front wall, an integral second wall extending from said laterally extending first wall spaced from the front wall to define a groove, a third integral wall extending laterally from said second wall, and a fourth integral wall extending from said third wall and extending generally parallel to said second wall and cooperating with said second wall and third wall to define a groove, a generally U-shaped integral tongue extending from the other edge of said front wall, said tongue comprising spaced walls connected by an integral arcuate connecting portion, one of said walls of said tongue extending from said front wall, the other of said walls of said tongue extending from said connecting portion along the rear of the front wall of the tongue, said walls of said tongue being arcuate and spaced apart at the top and bottom and have intermediate arcuate portions, the distance on said tongue between the one wall and the free edge of the other wall of said tongue at the top and bottom of the tongue in the free, unflexed condition of the tongue being slightly greater than the width of said groove of the adjacent panel such that the tongue of one panel functionally engages the groove of an adjacent panel at the top and bottom and at the arcuate connecting portion.
