Flexible Foam for use as a Flexible Siding Backing Foam

Polypropylene or other flexible foams can be used as a backing material for flexible siding, including, aluminum siding, vinyl siding or polypropylene siding, see (Figure 1). The foam is adhered to the vinyl siding with a commercially available adhesive that does not need to be (but can be) applied over the entire surface of the vinyl. The glue or adhesive can be applied in strips or dabs or as an adhesive film provided in roll or sheet form or as an extrudate. The foam provides stiffness to support the flexible siding to make the siding look and handle more like wood siding. Compared to a conventional siding product (vinyl only without any support), vinyl siding-foam composite provides for better insulation, better impact resistance (the vinyl does not get damaged as easily by puncturing or indentation), better sound absorption, and the composite does not appear to be hollow (looks and feels like a higher quality product because the composite of siding and foam is stiffer).� Additionally, foam backed siding provides for more flexibility in making darker colored siding and using different designs. This is possible because the added strength that the foam provides allows for darker colors (less siding warping due to the added strength of the foam) and also longer siding sections. The flexible siding - foam composite pieces are stronger and can be made longer due to the added stiffness from the foam. Additional property e...
