Advanced vacuum insulation panels encapsulated in a glass barrier.

Author(s) : GLICKSMAN L. R., SOLOMOU N.

Summary

Evacuated powder insulation systems have long been known to exceed the thermal performance of existing commercially available insulators, such as fiber glass and CFC-blown foam. Low cost perlite powder was used, because, provided that low pressures are maintained within the panel by using a glass gas permeation barrier, its thermal conductivity is very similar to the thermal conductivity of other finer and more expensive powders, such as silica. The individual plastic-enclosed evacuated powder panels, encapsulated in a thin glass barrier, were put together in a matrix structure so that even if one individual panel is punctured or damaged, the insulating performance of the entire matrix is not significantly affected.
