A window assembly is formed of an inside facing vinyl extrusion portion and an outside facing aluminum extrusion portion which are interconnected by resilient snap-fit barb-like connectors integral with each extrusion, thus forming a composite type construction. The metal outside facing portion provides strength, durability and weather resistance; while the vinyl inside facing portion improves thermal insulation characteristics, reduces or eliminates sweating, and enables color, pattern, and other design aesthetics conveniently to be included in the window assembly. The window assembly may be virtually any type, such as the fixed light (window glass) type, sliding type, double hung type, picture type, etc.

a window assembly comprising a frame and at least one sash, at least one of said frame and sash including as composite structure first and second elongate, generally parallel members of dissimilar materials assembled to form such frame or sash, and resilient lock means for securing said members together in positive locked parallel relation, at least one of said members being relatively rigid and at least one of said members being of lower thermal conductivity than the other, said resilient lock means comprising a pair of interlocking barb protrusions, each on a respective member and each having a sloped surface to slide against the sloped surface of the other barbed protrusion during locking of said members together and a stop surface cooperative with the stop surface of said other member to prevent separation of said members, each barb protrusion being located at an end of a stem connected with a respective member, the stem of at least one of each respective pair of the barb protrusions being resiliently deflectable during locking of said members, and force applying means proximate to the resiliently defectable stem of said at least one of each respective pair of the barb protrusions for maintaining the integrity of the interlock of each respective pair of the barb protrusions.
