Claims14
A laminated panel comprising;
- an extruded, outer, thermoplastic, facing sheet having a fibrous material embedded in an interior face thereof with fibrous material projecting from such face, and
- a rigid foam layer contiguous to said interior face with said projecting fibrous material projecting into and entrapped in said foam layer to mechanically join said layer to said outer facing sheet.
A laminated building panel comprising:
- an extruded outer PVC facing sheet having fiberglass embedded in an interior face thereof and projecting inwardly from such interior face;
- a rigid foam layer contiguous the interior face of said outer facing sheet with said inwardly projecting fiberglass embedded in said foam layer to mechanically join said foam layer to said outer facing sheet;
- and
- an extruded inner ABS facing sheet contiguous an interior face of said rigid foam layer, said inner facing sheet having fiberglass embedded in interior and exterior faces thereof with the fiberglass in the face of said inner facing sheet which is contiguous said foam layer projecting into and embedded in said foam layer to mechanically join said inner facing sheet to said foam layer.
A laminated panel comprising:
- an extruded, outer, thermoplastic, facing sheet having a fibrous material embedded in an interior face thereof with fibrous material projecting from such face,
- a rigid foam layer contiguous to said interior face with said projecting fibrous material projecting into and entrapped in said foam layer to mechanically join said layer to said outer facing sheet, and an extruded inner, thermoplastic, facing sheet contiguous to an interior face of said rigid foam layer and joined therewith by fibrous material wherein said inner plastic facing sheet has a fibrous material embedded in and projecting from its interior and exterior faces.
An extruded thermoplastic sheet having a fiberglass mat with fibers randomly oriented therein on at least one face thereof with fibers in said mat projecting both into said sheet and away from said sheet.
An extruded thermoplastic sheet having a fibrous material on both faces of the sheet with said fibers in said fibrous material projecting both into said sheet and away from said sheet.
