Abstract: An inverted roof membrane assembly comprising: a) a waterproofing membrane suitable for direct or indirect mounting on top of a roof decking, b) at least one layer of the polymer foam insulation board directly or indirectly on top of a), c) a flame-resistant fabric shield directly or indirectly on top of b), said flame-resistant fabric shield having a water vapor permeability of 1.0 perm or greater; and d) a ballast layer directly or indirectly on top of c).

Abstract: An inverted roof membrane assembly (IRMA) includes decking, a waterproofing membrane above the decking, a layer of polymer foam insulation board above the waterproofing membrane, and ballast above the polymer foam insulation board layer. The polymer foam insulation board includes a polymer foam layer that includes an alkenyl aromatic polymer and an infrared radiation attenuator, and first and second facer layers.

Abstract: A process includes: (a) providing a tantalum-coated metal alloy substrate; (b) heat annealing the tantalum-coated metal alloy substrate by heating to an annealing temperature for the tantalum-coated metal alloy substrate, holding at the annealing temperature for a period of time and then quenching to a temperature below 50 degrees Celsius; (c) heating the tantalum-coated metal substrate to the precipitation hardening temperature of the metal alloy substrate; and (d) cooling the tantalum-coated metal alloy substrate to a temperature below 50 degrees Celsius; wherein the process is further characterized by carrying out steps (b)-(d) under a tantalum-inert gas atmosphere and by quenching in step (b) and cooling in step (d) being carried out by flowing a tantalum-inert gas having a temperature of less than 50 degrees Celsius over the tantalum-coated metal alloy substrate.
