A method of forming a thermal insulation porous film includes mixing 100 parts by weight of polysilsesquioxane-containing polymer, 20 to 75 parts by weight of surfactant, and 20 to 2000 parts by weight of solvent to form a thermal insulation coating material, wherein the polysilsesquioxane-containing polymer in the thermal insulation coating material is tube-shaped or sheet-shaped. The thermal insulation coating material is coated on a substrate, and then dried and sintered to form a thermal insulation porous film.

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.

A removable pipe insulation system comprising one or more components, each component comprising insulation in a waterproof covering with at least one opening for air to exit the covering during use. The insulation in the covering may be surrounded by an inside skin with a plurality of holes formed through hot micro perforation. The inside skin may be surrounded by an outside cover, which may be edged in elastic binding and which may attach to itself by hook and loop fastener. The component may be wrapped around a pipe element and secured to provide insulation to the pipe element while protecting the insulation from moisture and protecting the pipe element from corrosion under insulation.

A method of forming an insulated structure for an appliance includes forming a structural enclosure having an outer wrapper and an inner liner and an insulating cavity defined therebetween, forming an insulating powder material, compacting the insulating powder material to form a pre-densified core material, disposing the pre-densified core material within an insulating cavity, wherein the insulating cavity is defined between the outer wrapper and the inner liner and expressing at least a portion of the gas contained within the insulating cavity, wherein the insulating cavity is hermetically sealed to define a vacuum insulated structure.

A pipe connection for conducting a fluid that is under pressure is provided, having two tubular connection parts for a conical clamping connection, which are screwed together by a union nut while one is inserted in the other, wherein each connection part has a conical sealing surface that contacts the other in a sealing manner and wherein an annular groove is provided in one of the sealing surfaces. In order to enable the pipe connection also to conduct a fluid having cycling or varying temperature, the inner of the two connection parts has thermal insulation on the inside of the pipe at least in the axial segment of the sealing surface of the connection part, wherein the thermal insulation tube has a cam or a collar on the outer surface, which engages in a recess, which is axially bounded by the two connection parts.
