ABSTRACT:
An interlocking building panel is provided having an intermediate portion and first and second interlocking portions at respective sides thereof which are adapted for interlocking engagement with interlocking portions of adjacent panels. The first interlocking portion is formed to define a first side wall having a lower and an upper segment intersecting at an obtuse, inwardly included angle and also formed to define a first lip extending inwardly from the upper segment. The second interlocking portion is formed to define a second upwardly extending side wall, an outwardly extending upper wall, a leg depending from said upper wall, and a second lip extending inwardly from the leg. In two embodiments, the upper wall also extends outwardly from the depending leg to define a fastening surface, while in a third embodiment, the depending leg is spaced outwardly from the second side wall sufficiently to provide a fastening surface in the upper wall between them.
