The present invention is a vacuum insulated panel (VIP) for increasing the thermal insulation surrounding a structure or volume, and a novel method for manufacturing the VIP. The VIP comprises at least two pieces of thin metal foil welded together adjacent the edges of said metal foil, said thin metal foil material defining the exterior of a sealed and gas evacuated vacuum enclosure; and a vacuum insulation panel core located between said at least two pieces of welded thin metal foil material, said vacuum insulation panel core located inside said sealed and gas evacuated vacuum enclosure.

1. A method for making a vacuum insulated panel for decreasing heat leakage from a structure, comprising: enclosing a core of the vacuum insulation panel between two thin sheet metal foils, each thin sheet metal foil is thinner than 0.003 inch, has a thermal conductivity lower than 26 W/(m×K), the t
1. A method for making a vacuum insulated panel for decreasing heat leakage from a structure, comprising: enclosing a core of the vacuum insulation panel between two thin sheet metal foils, each thin sheet metal foil is thinner than 0.003 inch, has a thermal conductivity lower than 26 W/(m×K), the thin sheet metal foil material selected from the group consisting of stainless steel, titanium, and other low thermal conductivity metals;welding said two metal foils directly together continuously on three sides adjacent the edges of said metal foils, forming an enclosure between said metal foils, said enclosure having at least one opening communicating with an interior of said enclosure;clamping the remaining open side of said two metal foils together;evacuating gas from the enclosure through said opening; andwelding the remaining open side of said two metal foils together after the enclosure formed by said two metal foils has been evacuated of gas. 2. The method of claim 1, further comprising: removing the portion of said two metal foils disposed on the outside of the weld of said remaining open side of said two metal foils, after said remaining open side has been welded. 3. The method of claim 1, wherein: said two metal foils are welded together using a welder selected from the group consisting of a seam welder, a laser, a plasma welder and a brazing system. 4. The method of claim 1, wherein: said two metal foils are welded together to create a continuous gas tight seam around said enclosure after gas has been evacuated from said enclosure. 5. The method of claim 1, wherein said method comprising: delivering a getter to the interior of said enclosure through said opening of the two metal foils immediately prior to welding the remaining side of said two metal foils. 6. The method of claim 1, wherein: said at least one opening comprises multiple orifices adapted at one side of said enclosure to increase the speed of gas evacuation. 7. The method of claim 1, wherein: said at least one opening comprises multiple orifices located at different sides of said enclosure to increase the speed of gas evacuation. 8. The method of claim 1, further comprising: pumping edge leaks with an additional vacuum pump when there is a leak on said clamped remaining side along the edge of the enclosure. 9. The method of claim 1, wherein: said enclosure comprises arbitrary sizes and shapes, selected form the group consisting of square, trapezoidal, rhomboid, circular, rectangular, and pillow-shaped. 10. The method of claim 1 further comprising: welding said two metal foils together along single connected or multiple connected paths. 11. The method of claim 1 wherein said core of the vacuum insulation panel is composed of material selected from the group consisting of fumed silica, a tensile structure, and mechanical structures. 12. The method of claim 1 wherein said core of the vacuum insulation panel is adapted to support an external pressure of at least one atmosphere while minimizing the transfer of heat across the vacuum insulated panel. 13. A vacuum insulated panel for decreasing heat leakage from a structure prepared by a process comprising the steps of: enclosing a core of the vacuum insulation panel between two thin sheet metal foils, each thin sheet metal foil is thinner than 0.003 inch, has a thermal conductivity lower than −26 W/(m×K), the thin sheet metal foil material selected from the group consisting of stainless steel, titanium, and other low thermal conductivity metals;welding said two metal foils directly together continuously on three sides adjacent the edges of said metal foils, forming an enclosure between said metal foils, said enclosure having at least one opening communicating with an interior of said enclosure;clamping the remaining open side of said two metal foils together;evacuating gas from the enclosure through said opening; andwelding the remaining open side of said two metal foils together after the enclosure formed by said two metal foils has been evacuated of gas.
