When a foamed resin metal laminated sheet (1) heated in a heating furnace (11) is cooled to room temperature, the foamed resin metal laminated sheet (1) is held at soaking temperature in a soaking bath (21) to make the temperature of the foamed resin sheet uniform over the entire area of the foamed resin metal laminated sheet (1), and then cooled to room temperature in a room temperature cooling unit (22). Thus, rippling due to thermal strain can be suppressed.

A method comprising providing a polymeric substrate having a melting point of from about 130 C. to about 190 C., and locating a material layer onto the substrate, wherein the material layer comprises one or more polymeric materials that liquefy upon exposure to temperatures of at least about 100 C., to blend with a softened portion of the polymeric substrate. Upon exposure of one or more of the substrate and the material layer to a stimulus, the temperature is increased in a predetermined temperature zone of one or more of the substrate and material layer to cause blending of the one or more polymeric materials of the material layer with the softened portion of the polymeric substrate.

A method of producing a combination structural member and surface coating or covering, and the product so produced. The surface covering is composed of at least two layersan outer layer of vibration oriented polymer granules adhesively bonded together at a density that allows the layer to be highly porous to liquid and such that it presents a non-planar upper surface for enhanced traction, and a bonding/sealing inner layer formed of an aliphatic urethane bonding agentthe bonding/sealing agent producing a liquid impermeable barrier on the structural member. The bonding/sealing layer is applied as an uncured inner layer on the structural member and the polymer granules are then applied onto the bonding/sealing layer.

A construction board comprising (a) a foam core having a first planar surface and a second planar surface; (b) a facer, having first and second planar surfaces, including an inorganic fabric and a coating; and (c) an interfacial region between the foam core and said facer.

A method includes providing a production line configured for continuous fabrication of polymer or predominantly polymer roofing boards by setting and expansion of precursor materials on a conveyor. A first polymer or predominantly polymer material foam precursor is dispensed to the production line, and allowed to rise and at least partially set to form a foam core layer for an insulation board, the foam core layer for the insulation board having a first density. A second polymer or predominantly polymer material foam precursor is dispensed to the production line and allowed to rise and set to form a core layer for a cover board, the foam core layer for the cover board having a second density greater than the first density. The combined thickness of the foam core layer for the insulation board and the core layer for the cover board is set by constraining the expansion of the combined foam precursors using a downstream forming conveyor disposed above the rising foam precursors.

A method for the manufacture of a polymer foam composite includes forming a polymer foam that is at least partially uncured; contacting the formed polymer foam with a fibrous mat including a plurality of nonwoven fibers having an average diameter of 100 um or less under conditions effective to infiltrate a portion of the polymer foam into the mat, to provide a pre-composite; and curing the pre-composite to form the polymer foam composite. The pre-composite includes a polymer foam layer and an intermixed layer including the fibrous mat and the same polymer as the polymer of the polymer foam layer. The polymer foam composite includes a cured polymer foam layer and an intermixed layer integrally bonded to the first layer, wherein the intermixed layer includes the fibrous mat and a cured polymer the same as the polymer of the cured polymer foam layer.
