Multi layer insulation mli is thermal insulation composed of multiple layers of thin sheets and is often used on spacecraft and cryogenics it is one of the main items of the spacecraft thermal design primarily intended to reduce heat loss by thermal radiation in its basic form it does not appreciably insulate against other thermal losses such as heat conduction or convection. Multi layer attic insulation based on nasa technology 99 9 pure aluminum reflects 97 radiant heat keeping the heat cold from entering your home through the attic. Multilayer insulation material guidelines multilayer insulation material guidelines provides data on multilayer insulation materials used by previous spacecraft such as spacelab and the long duration exposure facility and outlines other concerns.

The data presented in the document are presented for information only. Imli uses discrete spacer technology to improve thermal performance and predictability and offers significant advantages over traditional mli and spray on foam insulation sofi. Improving the efficiency of your hvac means less energy used to cool heat your home. Ungar crew and thermal systems division nasa johnson space center houston tx.

They can be used as guidelines for multilayer insulation design for future. Multi layer insulation blankets consist of multiple layers of thin plastic film coated on one or both sides with an aluminized reflective material.
