Abstract
This invention deals with casings useful for fabricating articles used in insulation methods and a blanket type thermal insulation formed from such articles that can be placed on substrates to prevent exaggerated changes in temperature of the substrate. The flexibility of the blanket allows for its use on a variety of configurations of substrates.
Claims29
A casing for use in containing thermal insulation, said casing comprising
- a flexible housing having spaced apart opposing side walls, said side walls being connected to each other by a plurality of flexible fasteners which cause the side walls to cooperatively define at least two chambers therebetween;
- a means for detachedly fastening said casing to another adjacent similar casing;
- a means for detachedly securing said casing on a substrate.
An article for thermally insulating a substrate, said article comprising
- a flexible casing said casing comprising a flexible housing having spaced apart opposing side walls, said side walls being connected to each other by a plurality of flexible fasteners which cause the side walls to cooperatively define at least two chambers therebetween;
- there being contained in each said chamber, insulative material sufficient to thermally insulate said substrate;
- a means for fastening the casing to another similar casing;
- a means for detachedly securing said article on the substrate.

A method of constructing a casing, the method comprising
- (I) providing a first side wall;
- (II) providing an opposing second side wall to form a cavity therebetween;
- (III) providing at least one divider wall disposed between the first side wall and the opposing second side wall and forming at least two chambers from the cavity by securing each of the divider walls to the side walls, each said divider wall being alternatively secured to said opposing side walls.
A method of constructing an article, the method comprising
- (I) providing a first side wall of flexible material;
- (II) providing an opposing second side wall of flexible material to form a cavity therebetween;
- (III) providing at least one divider wall disposed between the first side wall and the opposing second side wall and forming at least two chambers from the cavity by fastening each of the divider walls to the side walls, each said divider wall being alternatively secured to said opposing side walls;
- (IV) filling the chambers formed thereby with a thermal insulating material, and
- thereafter,
- (v) sealing the article to prevent the escape of the material of (IV) .
