ABSTRACT:
A combination fastener and foam sheet having enhanced fastener retention and methods of forming a foam sheet are provided so that the fastener is not easily removed from the foam sheet when an outward force is applied thereto. The combination preferably includes a foam sheet including a fibrous material and urethane foam material abuttingly contacting and substantially surrounding the fibrous material so that the fibrous material is substantially contained within and retained by the urethane foam material. The combination also, preferably includes a fastener having threaded portions positioned within the foam sheet so that the threaded portions are retained in the foam sheet and are not easily removed when an outward force is applied thereto. The foam sheet preferably also has a strengthening material such as glass also substantially surrounded by the urethane foam.
