Abstract
Foamed polymer-fiber composites, building materials and methods of making such building materials are provided by this invention. The composites include about 35-75 wt. % of a polymeric resin, about 25-65 wt. % fiber and have a specific gravity of less than about 1.25 g/cc. The low density is provided by the introduction of a blowing agent or gas into a molten precursor of the composite during thermo forming, such as in an extrusion operation.
