ABSTRACT:
A composite sill assembly including a core covered by an extruded section of aluminum cladding and a cover plate of brass fastened to the outer surface of the cladding to improve the appearance of the assembly without appreciably increasing its cost. Opposing surfaces of the cover plate and cladding are isolated from each other to prevent corrosion through galvanic action and this may be accomplished by adhering the cover plate to the cladding with a double faced adhesive tape of foamed neoprene or other suitable material. In this construction the tape therefore serves the dual function of both securing the plate to the cladding and isolating the two members from each other to prevent galvanic reaction and corrosion.
