The present disclosure relates generally to polymer structures, for example, suitable for construction products. The present disclosure relates more particularly to a thermoplastic construction product including a coextruded layer structure having a base layer including a first thermoplastic material, an outer layer including a second thermoplastic material, and an infrared-reflective intermediate layer that is coextruded with the base layer and the outer layer and is disposed between the base layer and the outer layer. In some embodiments the intermediate layer has a thickness of at least 30 micrometers. In some embodiments the infrared-reflective intermediate layer includes a reflective pigment dispersed in a matrix of one of the first thermoplastic material or the second thermoplastic material.

A method for covering a roof, the method comprising (i) providing first and second silicone membranes, where the membranes are in the form of rolls; (ii) unrolling the first and second silicone membranes over a roof surface; (iii) positioning first and second membranes adjacent to one another and overlapping and edge of the second over an adjacent edge of the first membrane to thereby form a lap; (iv) securing the first and second membranes to the roof surface; and (v) seaming the first membrane to the second membrane in the lap.

A method of fixing a membrane to a surface is disclosed. The method includes affixing a metallic washer having a heat-activated adhesive layer on a surface; arranging a membrane on top of the surface and the heat-activated adhesive layer of the metallic washer; heating the metallic washer to activate the heat-activated adhesive layer such that the membrane is fixable to the metallic washer; positioning a magnetic clamping heat sink assembly on the membrane; magnetically clamping the magnetic clamping heat sink assembly to the metallic washer causing the magnetic clamping heat sink assembly to apply a force against the membrane when the magnetic clamping heat sink assembly sufficiently overlaps the metallic washer to form a secure bond; and cooling the metallic washer, the heat-activated adhesive layer, and the membrane by removing heat through the magnetic clamping heat sink assembly.

The present disclosure provides a method, process and system for recycling an asphalt-based roofing material. In particular, the method, process and system are capable of removing and recovering an aggregate product, fiber product and an asphalt product from the asphalt-based roofing material. The aggregate, fiber and asphalt products each may be reused in a variety of applications.

A method of providing covers over at least a portion of a roof of a storm damaged built structure that includes the steps of: applying a sheet of heat shrinkable film over the portion of the roof, the sheet having a leading edge and a trailing edge and being a film of low density polyethylene including shrinking resins; wrapping portions of the leading edge around a first batten and attaching the first batten to the underside of a first eave or to the facia of the built structure; wrapping portions of the trailing edge around a second batten and attaching the second batten to the underside of a second eave or to the facia of the built structure at a location different than the first batten; and heating the sheet of heat shrinkable film to bring the film into conformity with the portion of the roof, wherein the heating step shrinks the sheet of film tight against the built structure to cover over the portion of the roof.

A method of joining overlapping thermoplastic roofing membrane components in which a first thermoplastic roofing membrane component and a second roofing membrane component are positioned in overlapping relationship between a pair of complementary molding surfaces. Heat is generated in a metal substrate and transferred by thermal conduction from the metal substrate to overlapping portions of the first and second thermoplastic roofing membrane components to locally melt and coalesce a portion or more of the thermoplastic material of the first thermoplastic roofing membrane component and a portion or more of the thermoplastic material of the second thermoplastic roofing membrane component. The molten thermoplastic material of the first and second thermoplastic roofing membrane components forms a zone of coalesced thermoplastic material that, upon cooling, forms a solid weld joint.

A weatherable, low heat build-up capstock system comprising an acrylic cap, a pigment system that is IR transparent to a greater degree than existing pigment systems, an IR reflective substrate, and an extrusion system for same.

This invention relates to a roofing, cladding, or siding module, comprising an underlapping region extending from a head edge of the module and an exposed region extending from a foot edge of the module. The length of the foot edge defining the length of the module. The underlapping region is adapted to be substantially covered by the exposed region of an adjacent or overlapping module when installed on a building surface. The module is formed of at least one layer of extruded material. The layer so formed comprises at least 40% w/w filler and/or reinforcement, and one or more polymer(s).

The present protective barrier is similar to those commonly installed beneath ceilings during construction work being performed on ceilings or roofs of buildings, wherein two or more sections are sewn together to construct the protective barrier. However, the present protective barrier also comprises a dustcover, which covers the seam entirely preventing dust from passing through holes created when the seam is sewn using a thread or similar means.

A method of molding a building product may include providing an injection mold with a plurality of gates located adjacent a perimeter of the injection mold. The method may further include commingling a first material and a second material into a flow. The second material may be a color that contrasts with a color of the first material. The method may include injecting the commingled flow into the plurality of gates to form an injection molded building product, and removing the molded building product from the injection mold. In addition, the second material may extend through an interior of the molded building product and appear as contrasting streaks on an exterior of the building product to form a variegated grain appearance.
