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 for applying a flexible cladding material to an outer surface of an insulation layer for a pipe section includes providing the insulation layer in the shape of a cylinder and providing first and a second supporting elements with a gap therebetween. A layer of the flexible cladding material is arranged between the insulation layer and the first and second supporting elements. The insulation layer and the supporting elements are moved in relation to each other in such manner that the insulation layer and at least part of the layer of the flexible cladding material is moved through the gap between the first and the second supporting elements. The two supporting elements are moved toward one other after the insulation layer and the layer of flexible cladding material has passed through the gap. The flexible cladding material is adhesively connected to the insulation layer during or after the steps.

An insulating member 2 comprising a vacuum insulation panel 10 in a board-like shape and an elastic body 12A, wherein the vacuum insulation panel 10 has a core material and a gas barrier film covering the core material, the core material is decompressed and encapsulated in an outer sheath formed of the gas barrier film, the elastic body 12A has a degree of elongation of at least 10%, an Asker F hardness of at least 10 and an Asker C hardness of at most 30, and the elastic body 12A is provided on the entire surface of an application surface 10a of the vacuum insulation panel 10.

A reusable insulation wrap may include a multilayer insulation member having at least one stretchable layer adapted to resist moisture and sized to closely wrap around an article, at least one insulative layer adapted to accommodate deformation of the at least one stretchable layer, and at least one protective layer adapted to be abrasion and moisture resistant and prevent damage to at least one of the at least one stretchable layer and the at least one insulative layer. A releasable fastener may be configured to close the multilayer insulation member in releasable engagement around the article; whereby, the wrap may be configured to stretch around and fit snugly on the article.

Thermal insulators having cold side flap seals are described. An example thermal insulator includes a first thermal blanket and a second thermal blanket to be coupled to the first thermal blanket. The first thermal blanket includes a first insulation section, a flap, and a second insulation section. The flap extends laterally from the first insulation section and has a first portion laterally adjacent the first insulation section and a second portion laterally adjacent the first portion. The second insulation section is located on the first portion. The second thermal blanket includes a third insulation section, a fourth insulation section, and a seal. The fourth insulation section has a third portion laterally adjacent the third insulation section and a fourth portion laterally adjacent the third portion. The seal is to be compressed between the third portion and the second portion when the second thermal blanket is coupled to the first thermal blanket.

A heat-insulating protective member for skid posts contains a needled blanket of inorganic fibers. At least some of the needled blanket has, disposed therein, an impregnation part where an oxide-precursor-containing liquid is adherent in an undried state. The impregnation part has a water content of 50-400 parts by mass per 100 parts by mass of the inorganic fibers of the impregnation part. The water content of the heat-insulating protective member is 50-400 parts by mass per 100 parts by mass of the inorganic fibers of the heat-insulating protective member. The oxide-precursor-containing liquid contains ingredients that, upon burning, yield a composition containing Al.sub.2O.sub.3 and CaO. The oxide-precursor-containing liquid is adherent in an amount of 2-50 parts by mass in terms of oxide amount per 100 parts by mass of the inorganic fibers of the impregnation part. A molar ratio of Al/Ca, in the whole impregnation part is 10-330.

An insulating material for an aerosol generating device includes an insulation sheet and a waterproof film arranged on at least one surface of the insulation sheet.

Sheet of insulating plates comprising successively placed lamellae of insulating plates attached to each other at their edge side which is cross directional in relation to the longitudinal direction of the sheet of insulating plates, alternately at the upper corners and lower corners of the cross directional edge sides, whereby thus formed uniform sheet of insulating plates comprising several lamellae of insulating plates can be folded into accordion-like folded stack of lamellae of insulating plates and unfolded again into a uniform sheet of insulating plates, which sheet of insulating plates has an upper surface and a lower surface. The upper surface of the sheet of insulating plates comprises a surface layer which is arranged in the longitudinal direction of the sheet of insulating plates alternately attached to and detached from the lamellae of the insulating plates in groups of two successive lamellae of insulating plates.
