Foil insulation for nuclear plant - has spacing dimples and lapped edges, giving lightweight construction without gaps

Thermal insulation consisting of metal foil is esp. intended for nuclear installations and consists of a number of spaced, metal foil layers imprisoning air between them; the arrangement is capable of accommodating thermal movements. Some or all of the metal foil sheets comprise embossed projections which forms virtual point contacts between the sheet of foil and the adjacent sheet. Pref. each alternate metal foil has embossed projections on both sides; and a perforated intermediate sheet is incorporated between other sheets, the perforations being fitted over the embossed projections. Minimal contact area between one sheet and the next is attained and, by staggering the embossed points from one sheet to another, a long thermal conduction path is ensured, resulting in the min. loss of insulating value. Gaps do not open up in the sheets due to thermal movement. Fixing is easy.

Insulating material board

An insulating material board for insulating hollow walls, ceilings etc., especially for automotive manufacture, consists of a mineral fibre mat (6) or a similar insulating material and at least one ventilation and drainage layer, which is formed by at least two folded thin films (2, 4) disposed upon each other, which form channel-like air spaces on the surface of the mineral fibre mat. A flexible board is obtained by parallel folding of the films, between which a flat film (3) is applied. The thin flexible films can consist of plastic or metal. ...

INSULATED CHIMNEY ASSEMBLY

Insulated Chimney Assembly Linear sections (101) of a chimney assembly (100) each include concentric outer, intermediate and inner sleeves (102, 104, 106). The inner sleeve (106) is interconnected at its lower portion (140) to the intermediate sleeve (104) through spaced apart U-shaped clips (142), while the upper portion of the inner sleeve (106) is allowed to float. The inner sleeve (106) is thus spaced apart from the intermediate sleeve (104) with an insulative air gap (136) therebetween. The air gap (136) and the particular connective arrangement of the inner sleeve (106) to the intermediate sleeve (104) allows for both linear and radial thermal expansion of the inner sleeve (106) caused by high temperature waste flue gases, and also facilitates engagement of adjoining linear sections (101).

The shroud is formed from sheet material and is cylindrical in shape. A plurality of spacers are associated with the sheet material. These spacers are designed to engage the outer surface of a duct to hold the cylindrical sheet material in radially outwardly spaced relationship to the duct, defining thereby an insulating air gap between the outer surface of the duct and the shroud. The angular space between the spacers serves as gas channels to permit gas to flow between the shroud and the outer surface of the duct, along the length of the duct. The shroud has a straight axially extending slot along its entire length for easy removal from a duct. An axially extending edge receiving pocket is formed on the shroud adjacent the slot for receiving the adjacent longitudinally extending edge of the slot to hold the shroud in a cylindrical shape and to provide a gas-tight closure for the slot.

In order to satisfy these properties, in the outer packing material for vacuum insulation material, a layered body including a gas barrier film and a thermally weldable film as constituting members is generally used (such as in Patent Documents 1 to 4).As the gas barrier film, a constitution of a base material such as a plastic film including an inorganic thin film such as a metal film or a metal oxide film on its surface has been known.
