An insulation article usable either by itself or to provide an increased efficiency to a fibrous insulating medium comprises a first plastic sheet with closed cells of entrapped air bonded to a metal foil sheet in turn bonded to a layer formed from a sheet of paper or other moisture absorbing material. Passages are formed through each of the layers to permit the passage of vapor and to regulate the flow of thermal energy.

This invention relates to insulation materials and, in particular, to thermal insulation materials having heat reflective properties. In particular insulation material according to the invention comprises a random array of elements as herein defined having at least a portion thereof deformed so as to increase the resilience of the elements and to assist in forming spaces between adjacent elements in the random array. In this specification the term element is used to include filaments of differen...

An insulation material comprised of multiple layers of treated newspaper spaced in relation to one another for use as side wall or ceiling insulation bats and wall board in older homes.

An insulation material comprised of multiple layers of treated newspaper in a compartmentalized air impervious resin container or use as side wall or ceiling insulation bats in homes or like structures.

The invention relates to a coating for insulation material, which coating comprises a metal layer, such as an aluminum layer, and a plastic layer. The plastic layer contains plastic that crystallises when heated. The plastic can more particularly be a polyamide.

An insulation film comprising an organosilicon polymer and an organic polymer such as polyarylene, polyarylene ether, polyimide, and fluororesin is disclosed, wherein the organosilicon polymer has a relative dielectric constant of 4 or less and has a dry etching selection ratio of 1/3 or less to silicon oxide, fluorine-doped silicon oxide, organosilicate glass, carbon-doped silicon oxide, methyl silsesquioxane, hydrogen silsesquioxane, a spin-on-glass, or polyorganosiloxane. The insulation film ...

Putty-like gap-filling compounds for insulation that can be utilized at temperatures from about -420.degree. F. (-250.degree. C.) up to about 500.degree. F. (260.degree. C.) are described herein. Embodiments of these compounds contain about 25-50 volume percent base material, about 50-75 volume percent microspheres, and about 0.1-0.3 volume percent catalyst. Embodiments of these compounds contain about 70-80 weight percent base material, about 20-30 weight percent microspheres, and about 0.1-0.5...

An insulation retainer is provided for mounting upon the threads of a threaded stud so as to retain insulation of various thicknesses upon a substrate to which the stud is attached. The insulation retainer includes an outer body member and an inner body member. Adjustment means are formed upon the interior surface of the outer body member and upon the exterior surface of the inner body member so as to permit ratcheting of the outer body member over the inner body member in small increments so as...

An insulation sheath for a pipe in a furnace is provided. The sheath has excellent insulation properties together with adequate resistance to the corrosive environment and thermal shock conditions. A pre-formed, substantially C-shaped, elongate member shaped to conform to the pipe over a portion of its circumference, the member comprising an inner layer of bonded insulating material integrally-bonded to a protective outer layer of refractory material. The inner layer is preferably formed of bond...

The invention relates to a coating for insulation material, which coating comprises a metal layer, such as an aluminum layer, and a plastic layer. The plastic layer contains plastic that crystallizes when heated. The plastic can more particularly be a polyamide.
