A method of forming a polymeric vacuum insulation board is provided, the polymeric vacuum insulation board including a plurality of evacuated, closed-cell pores therein. In one embodiment, the method includes intermixing a polymer with zeolite particles that contain water and extruding the resulting composition under high pressure. During extrusion, water in the zeolite particles evaporates and creates a porous, closed-cell microstructure within a polymer matrix. As the polymer matrix cools and solidifies, water vapor is reabsorbed by the zeolite, which at least partially evacuates the closed-cell pores. In another embodiment, the method includes intermixing a polymer with expandable graphite particles and extruding the resulting composition under high pressure. During extrusion, the expandable graphite particles define evacuated voids. The polymer binder can be selected to include low gas permeance, for example ethylene vinyl alcohol (EvOH) or polyvinylidene chloride (PVDC). In some applications, the polymer can be blended with nano-clays or other additives to further decrease the gas permeance of the vacuum insulation board.

A vacuum adiabatic body includes a first plate; a second plate; a seal; a support; and an exhaust port, wherein an extension tab extending toward the third space to be coupled to the support is provided to at least one of the first and second plates, and the extension tab extends downward from an edge portion of the at least one of the first and second plates.

Vacuum insulation panels, methods for manufacture thereof, and applications thereof are described. The vacuum insulation panels comprise a porous insulating core encapsulated in an envelope to which a vacuum is applied. The envelope is coated with a waterproof coating layer which increases the robustness of the vacuum insulation panel.

The invention involves using composite panels to a framework to create a standard reusable rapidly deployable building structure, even in remote areas under favourable weather conditions. The invention discloses a minimal set of components, assemblies and methods where logistics are simplified through the use of flat-pack shipping and minimal use of field fasteners/tools. No crane or specialized trades are required to construct the building on site Standardization allows for interchangeability of components for repair or changing of building dimensions either during the initial construction or later. Most components are commercially available materials joined into assemblies using simplified manufacturing operations to reduce costs. Most assemblies, including flanges and cleats connecting adjacent composite panels, rectangular and/or triangular lattice (truss), transom, pier, columns, shear pins with retention means, are re-usable should the building require repairs, re-purposing or relocation. A free-span interior is described maximizing flexibility for arrangement of interior rooms and furnishings.

A vacuum adiabatic body includes a first plate, a second plate, a seal that seals the first plate and the second plate to provide a space between the first plate and the second plate in a vacuum state, a support including at least a pair of support plates that maintain a distance between the first and second plates, a thermal insulator including at least one radiation resistance sheet provided between the pair of support plates to reduce heat transfer between the first plate and the second plate, and an exhaust port through which a gas in the space is exhausted.

A method of making a board or mat, includes forming a liquid slurry with solids including inorganic fibers and cellulose fibers, forming a web from the slurry on at least one foraminous element, extracting water from the web, and drying the web to make a product, wherein the pH of the liquid slurry including the inorganic fibers and cellulose fibers is in the pH range of 2-6 and wherein the cellulose fibers have a Schopper-Riegler index of ≥50 according to ISO 5267.

Recent progress in passive radiative cooling technologies have significantly improved cooling performance under direct sunlight. Performance of existing passive radiative coolers for air conditioning and portable refrigeration applications can be improved with a material that is solar reflective and infrared transparent that can also have a low thermal conductivity.

A vacuum adiabatic body and a refrigerator are provided. The vacuum adiabatic body includes a support that maintains a vacuum space between a first plate and a second plate.
