Based on experience, under the above conditions, production of at least 80-120 silver atoms per sulfonated center is adequate to provide a total metallic-type barrier to the passage of air. These extremely thin silver layers, when part of a vacuum-treated thermal insulation panel, conduct very little heat around the rims of the panel as is needed to achieve the desired high thermal insulation. For example, the thermal conductivities of an appropriately formed panel is typically as low as 0.007 watts m /m2oC as compared to values for polystyrene and polyurethane foams of 0.03-0.04 watts m /m2°C and 0.016-0.025 watts m /m2oC, respectively (3). ... 

In case of the thermal insulation, the technical limits are nearly reached today and a further improvement will affect aspects like the units transparency (yiP - Vacuum Insula-ti(Mi Panels) or their maximum size, not mentioning the costs. A functional transparent vacuum insulating unit with U-values of 0.1 W/(m K) is not available by now due to the technical problems of keeping the system permanently gas-tight. Therefore, the use of translucent Silica Aerogels, as a highly efficient insulating material inside the/Gf/ s cavity, represents the best possible thermal insulation at the moment.

Kapton tape is the most appreciated with respect to the high temperature resistance of Kapton, intensively used as dielectric insulator of solar cell panels. The Kapton tape is associated with acrylic or fully reticulated silicon adhesives outgassing is the driving factor for the choice of the adhesive part of the tape, the unwanted event being the bubbling between the tape and the adherend under vacuum.
