A vacuum insulation panel manufacturing method that makes it possible to manufacture low-cost, high-performance vacuum insulation panels, and a vacuum insulation panel are provided. This method of manufacturing a vacuum insulation panel (1) involves: a stacking step in which a first metal plate (20) is stacked on one side of an insulating core material (10), and in which a backing member (50) having an opening (51) and a second metal plate (30) having an evacuation port (32) are stacked, with the opening (51) and the evacuation port (32) stacking, on the other surface of the core member (10) in the order of backing member (50) and second metal plate (30) from the core member (10) side; a first welding step for welding outwards of where the core member (10) is arranged in the first metal plate (20) and the second metal plate (30); an evacuating step from the evacuation port (32) to create a vacuum in an inner area which is held between the first metal plate (20) and the second metal plate (30) and in which the core member (10) is arranged; and a laser welding step in which, in a state in which the inner area is made into a vacuum by the evacuating step, the evacuation port (32) is sealed by means of a sealing material (60) and the sealing material (60), the second metal plate (30) and the backing member (50) are laser welded.

An insulative construction product includes a polyurethane foam core and a mixture of Aerogel and carbon black that is disposed within the polyurethane foam core. The mixture of Aerogel and carbon black includes between 90 and 99 weight percent Aerogel and between 1 and 10 weight percent carbon black. The polyurethane foam core includes between 10 and 90 percent by volume of the of Aerogel and carbon black mixture and the construction product has an R-value of at least 8.0 R/inch.

Embodiments of the present invention are based, at least in part, on the discovery of methods for encapsulating fragile insulation materials within polyisocyanurate foam to thereby provide a construction board having an advantageous balance of insulating properties and mechanical durability.

A vacuum insulation body comprising at least one vacuum-tight covering that surrounds at least one evacuated region, wherein one or more core materials are arranged in the evacuated region, and wherein the vacuum-tight covering has at least one evacuation opening that is provided with at least one valve having at least one valve disk that opens the evacuation opening in the opened state and that releases the evacuation opening in the closed state, with means for a vacuum-tight sealing of the evacuation opening being arranged outside the sealing region of the valve disk.

A vacuum heat insulating material includes a sheath material and a core material that is sealed inside the sheath material in a hermetically sealed decompressed state. The sheath material comprises a gas barrier layer and heat sealing layer. Heat sealing layer contains a heat sealing resin and filler with an aspect ratio exceeding 1. In heat sealing layer, at least some of filler is oriented, with a long-axis direction intersecting with a direction in which heat sealing layer spreads. Accordingly, there is provided a vacuum heat insulating material capable of preventing entry of a gas to the inside and favorably ensuring the hermetically sealed decompressed state on the inside.

Provided are vacuum-insulated articles comprising inner and outer tubes that define an evacuated space therebetween, one or both of the inner and outer tubes optionally comprising a flared region and a joint region that define a trough into which brazing or other material can be applied to facilitate sealing the inner and outer tubes to one another.

The invention relates to a thermal insulation moulded body (1) comprising a thermal insulation layer (2) made of one or more insulation materials (3) and a cover layer (4), characterized in that the cover layer (4) is formed by a polyurea, obtained from a polyaddition-polymerisation reaction of an aromatic or aliphatic isocyanate and an OH-group-free polyamine with a terminal amine group, wherein the cover layer (4) is arranged on the thermal insulation layer (2) or the thermal insulation moulded body (1).

A vacuum insulation panel manufacturing method that makes it possible to manufacture low-cost, high-performance vacuum insulation panels, and a vacuum insulation panel are provided. This method of manufacturing a vacuum insulation panel involves: a stacking step in which a first metal plate is stacked on one side of an insulating core material, and in which a backing member having an opening and a second metal plate having an evacuation port are stacked, with the opening and the evacuation port stacking, on the other surface of the core member in the order of backing member and second metal plate from the core member side; a first welding step for welding outwards of where the core member is arranged in the first metal plate and the second metal plate; an evacuating step from the evacuation port to create a vacuum in an inner area which is held between the first metal plate and the second metal plate and in which the core member is arranged; and a laser welding step in which, in a state in which the inner area is made into a vacuum by the evacuating step, the evacuation port is sealed by means of a sealing material and the sealing material, the second metal plate and the backing member are laser welded.

An energy efficient film comprising of first and second substrate layers and microstructures positioned between the first and second substrates is provided. The microstructures are positioned between the first and second structures such that a vacuum environment is created between the first and second substrates. In one embodiment, the insulating film includes a first substrate, a second substrate, and a plurality of microstructures positioned between the first substrate and the second substrate, such that a vacuum environment is created between the first and second substrates and within each microstructure cell, individually. Preferably, the plurality of microstructures is a polygonal cellular network positioned between a first transparent substrate and a second transparent substrate. A gasket may be provided on one or both of the first or second substrates. The gasket may also be provided on outer edges of the first and/or the second substrate.
