Принадлежит: Cool Angle LLC

A roofing material has multiple coatings with at least one directionally disposed coating. The roofing material has at least one non-planar surface for exposure to environmental conditions. A first coating is directionally disposed on a portion of the non-planar surface to cover less than all of the non-planar surface. The first coating has a visual attribute and an energy-efficiency attribute which are both different from corresponding visual and energy-efficiency attributes of the non-planar surface on which the first coating is disposed. A second coating is directionally disposed on at least a portion of the first coating. The second coating has a visual attribute which is different from the visual attributes of both the first coating and the non-planar surface.

Disclosed painted roof coverings and related methods of manufacturing such painted roof coverings that use a color coating over the roof coverings instead of embedded pre-colored rock granules on the exposed surface of the roof coverings. By painting a roof covering with a color coating, any kind of top surfacing material, such as rock, plastic, mineral, man-made, or organic granules, may be used in place of the pre-colored rock granules. In some embodiments, it is desirable to size the top surfacing material to provide adequate UV protection and coverage to the weatherproofing asphalt material located below the top surfacing material. Further, the color of the shingles may be accurately matched between batches of shingles, between manufacturing facilities, and even between manufacturers. In addition, designs may be painted on the surface of the roof covering, which was previously impossible using pre-colored granules.

A high speed granule delivery system and method is disclosed for dispensing granules in intermittent patterns onto a moving asphalt coated strip in the manufacture of roofing shingles. The system includes a granule hopper and a rotationally indexable pocket wheel in the bottom of the hopper. A series of pockets are formed in the circumference of the wheel and the pockets are separated by raised lands. A seal on the bottom of the hopper seals against the raised lands as the wheel is indexed. In use, the pockets of the pocket wheel drive through and are filled with granules in the bottom of the hopper. As each pocket is indexed beyond the seal, it is exposed to the moving asphalt coated strip below and its granules fall onto the strip to be embedded in the hot tacky asphalt. The speed at which the wheel is indexed is coordinated with the speed of the asphalt coated strip so that granules and strip are moving at about the same forward speed or at a preselected ratio of speeds when the granules fall onto the strip. Well defined patterns of granules are possible at high production rates. 1.

Method and Apparatus for Sharp Color Definition on the Application of Granules to Roofing Substrates

Номер: US20150072073A1
Автор: Svec James A.
Принадлежит:

A high speed granule delivery system and method is disclosed for dispensing granules in intermittent patterns onto a moving asphalt coated substrate in the manufacture of roofing shingles. The system includes a granule hopper and a rotationally indexable pocket wheel in the bottom of the hopper. A series of pockets are formed in the circumference of the wheel and the pockets are separated by raised lands. A seal on the bottom of the hopper seals against the raised lands as the wheel is indexed. In use, the pockets of the pocket wheel drive through and are filled with granules in the bottom of the hopper. As each pocket is indexed beyond the seal, it is exposed to the moving asphalt coated substrate below and its granules fall onto the substrate to be embedded in the hot tacky asphalt. The speed at which the wheel is indexed is coordinated with the speed of the asphalt coated substrate so that granules and substrate are moving at about the same forward speed or at a preselected ratio of speeds when the granules fall onto the substrate. Well defined patterns of granules are possible at high production rates. A method for creating sharp linear color definition between granule patches at high line speeds also is disclosed. 1. A method of creating adjacent patches of different colored granules on an asphalt coated substrate moving in a downstream direction in the manufacturing of shingles , the method comprising the steps of:(a) defining a series of spaced apart first areas along the asphalt coated substrate designated to receive granules of a first color and defining a series of spaced apart second areas adjacent to and between the first areas designated to receive granules of a second color;(b) conveying the asphalt coated substrate along a production path in the downstream direction at a predetermined line speed;(c) applying a partial charge of granules of the first color into the first areas to create granule patches having a sharp leading edge, an indistinct ...

Disclosed is a shingle that uses a polyester sheet as a substrate layer. The polyester sheet has a sufficient weight and is needled and formed from two layers to resist shrinking upon cooling after the heated asphalt layers are applied to the polyester substrate sheet . In addition, additives may be included in the asphalt to lower the softening point temperature of the asphalt that further reduces shrinking of the polyester substrate or allows other polymers that are more fire retardant to be used. Fire retardants can be placed in the polyester sheet fibers, placed in the bonding agent for the polyester fibers, or the polyester sheet can be coated with the fire retardant. Alternatively, or in addition to treating the polyester sheet with fire retardant, fire retardant materials such as ammonium sulfate can be added to the liquid asphalt prior to application of the asphalt layers. 1. A method of making a roofing shingle comprising:forming a non-woven polyester sheet having a mass of at least 65 grams per square meter;coating said non-woven polyester sheet with a fire retardant;heating asphalt to a liquid state;applying said asphalt in said liquid state to a first side of said polyester sheet and to a second side of said polyester sheet;allowing said asphalt to cool in ambient air.2.
