Abstract:

A multilayer insulation has first and second outer polymeric layers having respective first and second outer metallized surfaces and respective first and second bonding layers inner side thereof. A third metallized coating is between the outer first and second polymeric layers. An air cellular assembly is between the first bonding layer and the second bonding layer. The air-cellular assembly has a plurality of air-filled cells between a first air cellular film and a second air-cellular film. In one embodiment, the third metallized coating is directly bonded to the first bonding layer, the second bonding layer, or a third bonding layer. Another embodiment has a total polymeric thickness of from 7 to 20 mils, a total thickness of from 1.5 to 4 centimeters, and an intrinsic normalized R-Value per inch of at least 2.9. A climate control duct can be surrounded by the multilayer insulation laminate.
