Abstract
A glass fiber reinforced building panel is made by extruding molten first and second webs of polymer compounds through spaced die openings, positioned a glass fiber mat between the first and second webs, pressing the webs and mat together, and cooling to form a building panel. The building panel of the invention has improved fire retardance and better field cutting and sawing performance compared with conventional, unreinforced building panels.
