Abstract: A method of coating highly reflective granules on an adhering material of a roofing or siding material to form a roofing or siding material having an average resulting reflectivity on an upper surface of at least about 45%. The method includes the selecting of highly reflective granules and applying the highly reflective granules on an adhering material until over about 95% of a top surface of the adhering material is covered by the granules.

Abstract: A light-weight structural system is provided by a panel system having at least one pair of adjacent panels (10) and a clip (60) positioned between the adjacent panels. A groove or channel (26) in each panel receives an outwardly-extending tongue or tab (70) on the clip. Built-up gussets (28, 30) on the panels above and below the groove or channel provide structural strength. Upwardly-extending support members (64, 66) on the clip bear weight from the panels. A base section (62) of the clip allows the clip to be fixed to a roof or wall substructure. The panels can be formed from thermosetting or thermoplastic polymers, especially fiber-reinforced polymers.

Abstract: A roofing or siding system having an improved average resulting reflectivity. The roofing and/or siding system is at least partially coated with a plurality of granules. The granules have an average reflectivity of at least about 55% and an average hardness of over about 3 Moh's.

Abstract: A composite substrate (10) is prepared for reinforcing a bituminous roofing material by securing together a carrier web (12) with a first set (14) of fiberglass rovings bundles and a second set (16) of fiberglass rovings bundles. The carrier web will have a pair of opposed planar surfaces. The web will define a machine direction and a cross machine direction for the substrate, with the first and second sets of rovings bundles each positioned in parallel relationship, with the longitudinal axes defined by the individual rovings of the two sets being in non-parallel relationship to each other when viewed normal to the plane of the web. The bundle sets are maintained in the spaced apart parallel relationships and the non-parallel angular relationship by the adhesive, stitching or other conventional method of securing which holds the substrate together. If a stitching machine is used, the preferred yarn (18) would be a polyester yarn.

Abstract: A roofing membrane which exhibits improved properties, particularly reduced propensity to blister, is produced by selecting a the group consisting of straight run asphalts with a rod & ball softening point in the range of from 80 to 130 degrees F.; oxidized asphalts, solvent washed asphalts, road tars, refined tars, and blends thereof; selecting a modifying polymer from a group consisting of: styrene-butadiene-styrene (“SBS”) block co-polymer, atactic polypropylene (“APP”), and a combination of SBS and APP; modifying the bitumen by adding the polymer while the bitumen is in a molten state in a sealed mixing vessel; exposing the modified bitumen to a pressure less than ambient during or after modification while still in a molten state to allow release of entrained gases; and forming the roofing membrane from the molten modified bitumen.

Abstract: A modified coal tar useful in roofing applications, containing coal tar, a nitrile butadiene rubber, and in some instances an effective amount of a plasticizer is prepared by heating the coal tar to a molten temperature, adding the rubber in powder form and agitating the material in a suitable high shear mixing apparatus until adequate phase inversion occurs between the polymer and the coal tar phase. After preparation, the material is cooled in containers until use, at which time it is heated to a flowable temperature and applied using a roofing mop or squeegee. Effective plasticizers include the alkyl esters of di-functional carboxylic acids, such as di-octyl adipate and di-octyl phthalate.

Abstract: Emulsions of asphaltic materials, such as asphalt or asphalt blends with polymers, in water using copolymeric anionic emulsifiers are disclosed. The copolymeric anionic emulsifiers use ionizable carboxyl groups as their hydrophilic moiety. The emulsions using these copolymeric emulsifiers are stable, allowing them to be used anywhere where asphalt or modified asphalt is used as a sealant, coating, or binder. These emulsions can also be mixed with polymer latices, pigments, fibers, fillers and other additives to impart particular properties specific to the type of application, i.e., pigmented flexible coating compositions, non-sag sealer and sealant compositions, water borne adhesive compositions, etc., for use in construction and industrial fields. These asphalt emulsions have better freeze-thaw stability, higher solids contents, and wider applicability to polymer modified asphalt compositions than prior art emulsions.
