a left side 30 and a right side 32 having complementary mating members 34 36 such that adjacent panels 1 can interlock or mate to form a continuous wall surface fig5 illustrates two such panels 1 that are joined together in this manner notably this system of interlocking panels creates a continuous insulated barrier in the embodiment shown in fig4 and 5 the mating members 34 36 include complementary l shaped ends however it is to be understood that other suitable interlocking or mating structures can be used for example a tongue and groove or jigsaw type mating arrangement could instead be used end panels 1 such as those meeting other panels at a corner can either be molded to not include the mating members 34 36 or a portion of core a adjacent mating members 34 36 can be removed by cutting it with a saw or hot wire for example referring to fig6 according to an embodiment of the present invention the stud 2 can be c shaped and have legs 40 42 extending from base 44 as shown each leg 40 42 can have an inwardly extending tab or barb 46 to assist in securing stud 2 to panel 1 in one embodiment the depth or thickness of core a can be about three times greater than the distance the legs 40 42 extend from the base 44 the stud 2 can be made from any number of strong relatively stiff structural materials such as for example metal plastic or composite materials in the embodiments shown in fig6 the stud 2 is formed from about 18 to 20 gauge galvanized steel sheet metal having the dimensions in inches as shown to create a wall structure one.
