Description
THERMALLY INSULATED PERSONAL ARTICLES
FIELD OF THE INVENTION
This invention relates to thermally insulated articles worn by a mammal, particularly human beings, and particularly to articles of clothing and footwear.
BACKGROUND OF THE INVENTION
Apparel and footwear worn by mammals, particularly human beings, are typically thermally insulated by means of a thick or a plurality of wool or other fabric layers per se or insulative foam, wool or other fabric material between an inner lining and the outer skin of cloth making up the jacket, trousers, coats and the like.
At present, satisfactory insulated apparel in cold or very cold environments generally need to be bulky to provide a satisfactory comfort level.
There is, however, a need to provide thermally insulated clothing that provides satisfactory thermal insulation that is not relatively bulky.
Reflective metal polymeric insulation materials are known in the construction industry, particularly for use in residential, commercial, and industrial buildings and establishments, wherein the insulation material is adjacent frame structures, walls, crawl spaces, ceilings, around water heaters and pipes and under concrete floors and roads.

Fig. 1 shows generally as 1, a person 2, wearing headgear 3, jacket 4, gloves
5, trousers 6 and boots 7 lined with reflective metal polymeric insulation material according to the invention.
With reference to Fig. 2, this shows generally as 100, a double layer, bubble-pack with aluminum foil insulation assembly adhered between the outer skin 202 and inner lining 204 of a jacket material. The double layer consists of a pair of bubble arrays 120, 140 bonded together through an intervening low density polyethylene film 160.
Arrays, 120, 140 are formed of a plurality of bubble or sealed cavities 180, 200, respectively, from a 5 mil polyethylene film 220, 240, respectively. Each of films 220, 240 at their outer surfaces is bonded to a reflective aluminum foil 260, 280, respectively, to provide the whole assembly with external aluminum surfaces.
Assembly 100 has approximately twenty, 1 cm diameter, 0.5 cm high bubbles per cm length and breadth within each of films 220, 240.
The aforesaid assembly 100 is made by a double hot roller thermal and vacuum forming process for cavity forming and lamination sealing techniques known in the art.
With reference to Fig. 3, this shows generally as 200 a composite double bubble-pack assembly according to the invention, having an aluminum foil 102 disposed between and bonded to bubble arrays 112 and 114 formed as for Fig. 2 assembly. Bubbles 118 and 120 are encapsulated between polyethylene films 116 and 128.
Aluminum foil 102 has a low emissivity value of less than 5% on each surface to essentially eliminate heat transfer by radiation.
Each of the single bubble-pack layers 112, 114 provides both thermal conduction and convection insulation, and, in combination with the aluminum surfaces, excellent radiation insulation.
The composite bubble-pack 100 offers significant resistance to heavy loading whereby appreciate non-breakage of the air bubbles is often found. Preferably, outer layers 128 are made slightly thicker than inner layers 116 to better resist abrasion.
Additional water resistance or abrasion resistant films may be bonded or formed laminated to layer 128.
Further, in consequence that composite assemblies of the invention have better thermal R-values than prior art assemblies, thinner or higher insulative assemblies may be provided.
