A vacuum insulated structure includes a first panel having an inner surface defining an area. The first panel includes a vacuum port. A trim breaker interconnects the first panel with a second panel in an air-tight manner to define a vacuum cavity therebetween. A first filter member is disposed on and substantially covers the area of the inner surface of the first panel and the vacuum port of the first panel. A second filter member substantially covers the first filter member to define a channel therebetween. The channel includes an area commensurate with the area of the inner surface of the first panel. The first panel may also include a mesh member covered by a filter member to define a channel therebetween to improve evacuation time using the channel to evacuate the vacuum cavity.

A method of manufacturing a vacuum heat insulator includes preparing a hollow body that has heat resistance equal to or higher than a level to withstand a flame of 781° C. for 20 minutes and that has a hollow portion in the hollow body, introducing, into the hollow portion of the hollow body, an inorganic foaming agent that has the heat resistance and foaming the foaming agent to form a foam having open cells, or introducing an inorganic foam having the heat resistance and open cells, and then solidifying the foam, and evacuating the hollow portion after the foam is solidified or during the solidification of the foam.

A temperature-stable vacuum insulation element 1 for use over a wide temperature range of high or low temperatures including a core material 2 of fumed silica in a proportion by weight in the range from 30% to 90%, a fiber material 3 in a proportion by weight in the range from 1% to 10%, an opacifier in a proportion by weight in the range from 5% to 50%; and a vacuum-tight envelope of the core material 2 of at least one stainless steel foil 4a, 4b.

A vacuum insulation assembly includes a number of vacuum insulation modules. Each module includes a first layer of material, a second layer of material substantially parallel to the first layer of material, a frame member disposed between the perimeter edges of the first and second layer of materials, a vacuum chamber formed between the first and second layer of materials and the frame member, and one or more spacers that generate a magnetic field. The spacers can be located on the interior, the exterior or disposed within the first and second layers of material. In one aspect, the spacers are permanent magnets, electromagnets, and the like, that are positioned such that the spacers provide a sufficient magnetic field to prevent the first and second layers of material from contacting each other.

A vacuum insulating material providing assembly, which can be used to provide the vacuum insulating material to the interior corners, exterior corners and/or window edge portions of a building, includes corner members positioned at the interior corners, exterior corners or window edges of the building, wherein the corner member has: a base plate; a first cantilever plate extending from one end of the base plate in the vertical direction; and a second cantilever plate extending from the base plate in the direction parallel to the first cantilever plate.

An assembly comprising at least one first pocket (3) which contains a thermally insulating material (5) and in which a first controlled atmosphere prevails, and at least one second pocket (7) which surrounds the first pocket and in which a second controlled atmosphere prevails. The first controlled atmosphere is different from the second one and corresponds to a vacuum of 10 Pa or less. The thermally insulating material (5) preferably has open cells with a diameter greater than or equal to 1 micron.

The present invention is a thermal and acoustic insulating sphere that has an evacuated hollow interior. The spheres are constructed of insulating materials, and the inner and outer surfaces of each sphere have highly reflective coatings evenly applied to them. The coatings applied to the inner and outer surfaces reduce the transmission of heat by conduction, convection, and radiation. Additionally, the spheres provide superior acoustic insulation due to the inability of sound to travel through the interior vacuum. The spheres can be used to produce insulating materials, for example, by embedding or positioning them within or between other materials, to provide thermal and acoustic insulation.

A vacuum adiabatic body may include: a first plate member; a second plate member; a sealing part sealing the first plate member and the second plate member to provide a third space; a supporting unit maintaining the third space; a heat resistance unit at least including a conductive resistance sheet capable of resisting heat conduction flowing along a wall for the third space to decrease a heat transfer amount between the first plate member and the second plate member; and an exhaust port through which a gas in the third space is exhausted. A side frame may be fastened to the conductive resistance sheet and the second plate member, and the side frame is fastened to an edge portion of the second plate member. Accordingly, the formation of dews may be prevented and an adiabatic effect may be improved.
