Abstract

A backerboard for use in conjunction with a siding panel of the type having longitudinally disposed walls connected by a longitudinal step and wherein the siding panel is normally fastened to the external wall sheathing of a building. The backerboard is adapted to be disposed between the inner surfaces of the siding panel walls and the exterior of the building sheathing. The backerboard is fabricated from two polystyrene foam plastic members that are disposed with respect to each other so as to have overlapping portions that are bonded to one another by a suitable adhesive such that the longitudinal side edge of one of the members adjacent the overlapping portions is contoured to snugly abut the step of the siding panel when the backerboard is positioned against the same. A method for manufacturing the backerboard is disclosed.

Claims

1. A method for assembling a prefabricated backerboard to the exterior wall surfacing of a building, said backerboard comprising a siding panel of the type having longitudinally disposed first and second walls connected by a longitudinal step wherein the siding panel being adapted to said building exterior wall, with the said backerboard being adapted to be disposed between the inner surface of the siding panel walls and the exterior surface of the building, said method comprising the steps of cutting a first sheet of insulating material such that the one surface thereof and one edge thereof, respectively, have a contour that is complementary to the inner wall surfaces of the siding panel and longitudinal step within which it is adapted to be utilized;

cutting a second sheet of insulating material such that the one surface thereof has a contour which is complementary to the wall surface of the panel member which said second sheet is adapted to abut and a width which is greater than said last mentioned wall surface such that the excess portion of said second sheet overlaps said first sheet;

overlapping said excess portion of said second sheet with a portion of said first sheet; and

bonding the overlapping surfaces of said sheets to each other, and thereafter assembling said prefabricated backerboard in position on the exterior wall of said building.

2. The product manufactured by the method defined in claim 1.

3. The method of manufacturing a backerboard as defined in claim 1 further comprising the step of positioning the backerboard in a complementary relationship with the inner surfaces of said panel walls and bonding said backerboard members to said panel wall inner surfaces.

4. The product manufactured by the method defined in claim 3.

5. A method of manufacturing a backerboard for a siding panel of the type having longitudinally disposed first and second walls connected by a longitudinal step wherein the siding panel is fastened to the external wall of a building and the backerboard is adapted to be disposed between the inner surface of the siding panel wall and the exterior of said building, said method comprising the steps of:

applying a plurality of parallel strips of adhesive to the top surface of a first sheet of insulating material of a preselected width, length, and thickness;

overlapping a second sheet of insulating material on top of said first sheet such that one side edge of said second sheet extends beyond the adjacent side edge of said first sheet, while on the opposite side of said sheets the side edge of said second sheet is inwardly spaced from the side edge of said first sheet;

applying pressure to said sheets to bond said first sheet to said second sheet; and

cutting the first and second sheets in a direction parallel to said strips of adhesive and at laterally spaced locations to form a plurality of backerboards having a first member and a second member with overlapping portions which are bonded to each other.

6. The product manufactured by the method defined in claim 5.
