A method of installing a binder-based overlay system may include contacting a layer of geotextile fabric to a surface of a substrate and applying a primer layer to a surface of the geotextile fabric. Two or more binder layers including infill particles may be applied over the primer layer. A resurfacer layer followed by one or more color layers may be applied over the two or more binder layers. The primer layer, one or more binder layers, resurfacer layer, and two or more color layers may cure upon application to form a monolithic layer upon the substrate.

A process for in-line extrusion of polymeric coatings onto roofing shingles during manufacturing includes moving a web of shingle substrate material in a downstream direction and extruding a liquefied coating of polymeric material onto at least one surface of the moving web to form a thin film. The liquefied coating may be a molten polymeric material that forms a thin film on a back surface of the shingle material to prevent sticking and eliminate the need for a traditional back dusting with material such as powdered stone. The polymeric film further may be applied to the substrate material in lieu of a saturation coating of asphalt, thus reducing cost and weight while providing a comparable moisture barrier and a lighter more flexible shingle.

A flexible pavement structure comprises a surface layer, a base layer, a sub-base layer, and a subgrade layer. Herein, the surface layer is adjacent to and above the base layer, and the sub-base layer is adjacent to and above the subgrade layer. The flexible pavement structure further comprises a layered system composed of first, second, and third materials different from each other, and is disposed as an interface layer between the base layer and the sub-base layer. The first material is a geotextile fabric selected from a group consisting of polypropylene and polyethylene, providing ground stabilization or reinforcement properties. The second material is a waterproof heat insulation material selected from a group consisting of cross-linked polyethylene foam and laminated aluminum foil, providing waterproofing or impermeability properties. The third material is a glass foamed insulation material.

Various embodiments disclosed relate to a composite shingle. The composite shingle includes a particle layer and a polyketone layer proximate to the particle layer.

A system includes a plurality of roofing modules and a plurality of photovoltaic modules. The roofing modules include a first layer and a second layer. The first layer has a first surface that is textured. The roofing modules are configured to be installed on the roof deck of a structure proximate to the photovoltaic modules. An appearance of the roofing modules aesthetically matches an appearance of the photovoltaic modules when viewed from a vantage point located at a ground level of the structure.

A method is provided for forming an adhered membrane roof system that meets Factory Mutual (FM) 4470/4474 standards for wind uplift. The method comprises applying a bond adhesive to a substrate on a roof to form an adhesive layer and applying a membrane directly to the adhesive layer. The bond adhesive includes a moisture-curable polymer.

A glass sheet composite having two or more glass sheets and a liquid layer between at least a pair of glass sheets out of the glass sheets, wherein a thickness of the liquid layer is 1/10 or less of a total thickness of the pair of glass sheets when a total thickness of the pair of glass sheets is 1 mm or less, and 100 μm or less when the total thickness of the pair of glass sheets is more than 1 mm.
