Abstract
An asphaltic roofing membrane is produced by applying asphaltic material to reinforcement, adding first granules without preheating, removing loose granules, applying second granules without preheating, heating the membrane and then cutting the asphaltic membrane; and rolling the cut membrane. The process supports granules of varying sizes, materials, and colors, resulting in a durable, high-reflectance roofing membrane.
Claims17
A method of manufacturing an asphaltic roofing membrane, comprising:
- applying an asphaltic material to a reinforcement material to form an asphaltic membrane;
- applying a first granules to a top surface of the asphaltic membrane to form a granular asphaltic membrane
- wherein the asphaltic membrane is not heated prior to or during the step of applying the first granules,
- wherein, from the start of applying the first granules until all loose first granules have been adhered, the asphaltic membrane is maintained in a planar configuration and is not in contact with or supported by any roll or arcuate surface;
- removing at least some of the first granules that have not adhered to the asphaltic membrane to form a granular asphaltic membrane;
- applying a second granules to the granular asphaltic membrane to form an asphaltic roofing membrane
- wherein the granular asphaltic membrane is not heated prior to or during the step of applying the second granules,
- wherein, from the start of applying the second granules until all loose second granules have been adhered, the asphaltic membrane is maintained in a planar configuration and is not in contact with or supported by any roll or arcuate surface;
- heating the asphaltic roofing membrane;
- after heating the membrane, cutting the asphaltic membrane;
- and
- rolling the cut membrane.
