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.
