Composite Siding System

Abstract

The present invention is an improved system of wall siding which provides a aesthetically appealing, weather resistant and maintenance free house cladding which has the appearance of wood siding. The system includes a plurality of elongated composite siding boards for mounting to the wall studs, each composite siding board having a length, opposite outer and inner sides and opposite upper and lower edges. The upper edge of each board has a tongue formed thereon which extends along the entire length of the siding board. The opposite lower edge has a groove formed thereon which also extends the entire length of the siding board. Each board has a shoulder portion extending from the inner side of the siding board adjacent the lower edge. The groove is formed on the shoulder adjacent the lower edge. The lower edge has a lower lip extending below the groove, the tongue and the groove being dimensioned and configured such that the tongue of one siding board can be snugly received within the groove of the siding board mounted immediately above. The board are mounted to the wall studs by a plurality of mounting clips, the mounting clips each having a flat portion and a sinusoidal portion, the sinusoidal portion being dimensioned and configured to fit in the groove between the groove of one siding board and the tongue of the adjacent siding board, the flat portion having an aperture for receiving a mounting element for mounting the clip to the wall stud.
