Abstract: Thermal breaker or thermal barrier structures are disclosed for use in connection with roof decking assemblies wherein the thermal breaker or thermal barrier structures effectively prevent the respective transmission of heating gradients from the interior or exterior building environments to the exterior or interior building environments by thermal conductivity so as to render buildings more energy efficient.

Abstract: An over-molded fitment is configured for mounting to a flexible packaging material. The fitment includes a flange having first and second sides, a spout extending upwardly from the first side of the flange and an over-molded sealing media molded onto the first side of the flange. The flange and spout are integral with one another and formed from a single first material. The over-molded sealing media is formed from a second material different from the first material and having a density less than a density of the first material. The sealing media permits joining the different materials of the flexible packaging and the fitment that would otherwise not seal to one another. A method for forming the over-molded fitment and a package formed with the fitment are also disclosed.
