Abstract
Disclosed is a building and construction material and process including multiple layers and vermiculite ore in at least one layer. A substrate layer may have one or more layers on top or on the bottom of it. Numerous compounds may be used in one or more of the layers including asphaltic compound, polymer modified asphalt compound, thermoplastic polymer compound and others. The layers may also include synergistic flame retardant and fillers. And disclosed is a process to manufacture the building and construction material.
Claims30
A building construction material comprising:
- a top compound layer;
- a bottom compound layer:
- a substrate layer;
- and
- unexpanded vermiculite ore incorporated in at least one of the top and bottom compound layers;
- wherein the building construction material achieves a Class A fire rating as tested by UL 790 criteria.
A building construction material comprising:
- a top compound layer;
- a bottom compound layer:
- a substrate layer;
- unexpanded vermiculite ore incorporated in at least one of the top and bottom compound layers;
- and
- synergistic flame retardant in at least one of the top and bottom compound layers.
A process for manufacturing a building construction material, the process comprising:
- depositing unexpanded vermiculite ore directly on a substrate layer;
- applying top and bottom compound layers onto top and bottom sides, respectively, of the substrate layer, wherein applying the top and bottom compound layers incorporates the unexpanded vermiculite ore in at least one of the top and bottom compound layers;
- wherein the building construction material achieves a Class A fire rating as tested by UL 790 criteria.
