Patent number: 11396752Abstract: An asphalt coated roofing shingle including a mat substrate saturated with asphalt, a top asphalt layer on a top surface of the mat, a bottom asphalt layer on a bottom surface of the mat, a granular layer on the top asphalt layer and a layer of melt-blown fibers applied to the bottom asphalt layer. A method for making a lightweight roofing shingle including the steps of saturating a mat substrate wherein the mat substrate has a top surface and a bottom surface; applying a top asphalt layer to the top surface; applying a bottom asphalt layer to the bottom surface; applying a layer of granular material to the top asphalt layer opposite the mat after the top asphalt layer is applied to the top surface; and applying a layer of melt-blown fibers directly to the bottom asphalt layer after the bottom asphalt layer is applied to the mat substrate.Type: GrantFiled: June 5, 2019Date of Patent: July 26, 2022Assignee: TAMKO BUILDING PRODUCTS LLCInventor: Cyril Chevillard

Patent number: 10982441Abstract: Disclosed is a multiple layer substrate that can be used with a top asphalt applicator that eliminates the need for a bottom asphalt applicator and fines applied to the bottom asphalt layer. A low porosity or impermeable bottom layer prevents the flow of asphalt applied to the porous top layers of the substrate from penetrating the bottom surface. This eliminates the need for fines to prevent sticking of shingles in a shingle stack. In addition, substrate layers that combine fiberglass and polyester fibers in various configurations provide a substrate that can be used in typical shingle manufacturing and manufacturing of waterproofing products that is impact resistant.Type: GrantFiled: March 2, 2019Date of Patent: April 20, 2021Assignee: TAMKO Building Products, LLCInventors: Cyril Chevillard, Aaron R. Phillips, James Gregory Powell
