Thermal insulators having cold side flap seals

Abstract:

Thermal insulators having cold side flap seals are described. An example thermal insulator includes a first thermal blanket and a second thermal blanket to be coupled to the first thermal blanket. The first thermal blanket includes a first insulation section, a flap, and a second insulation section. The flap extends laterally from the first insulation section and has a first portion laterally adjacent the first insulation section and a second portion laterally adjacent the first portion. The second insulation section is located on the first portion. The second thermal blanket includes a third insulation section, a fourth insulation section, and a seal. The fourth insulation section has a third portion laterally adjacent the third insulation section and a fourth portion laterally adjacent the third portion. The seal is to be compressed between the third portion and the second portion when the second thermal blanket is coupled to the first thermal blanket.
