Provided are insulative apparatus and methods of forming insulative apparatus. As an example, a method of forming an insulative apparatus can include connecting a barrier material to a mold; injecting a polyurethane foam composition into the mold, wherein the polyurethane foam composition includes a polyol, an isocyanate, and supercritical carbon dioxide; curing the polyurethane foam composition to form a polyurethane foam and applying a vacuum to the mold to provide a pressure from 1 millibar to 500 millibar.

Insulative apparatus

A gas diffuser including a grid of aeration pipes spaced apart and in parallel alignment within a horizontal plane is provided. The aeration pipes have improved discharge hole placement along their lengths and around their circumferences to provide improved performance and reduced fouling of membrane filtration systems associated therewith.
