Multi Layer Insulation Nasa

Imli uses discrete spacer technology to improve thermal performance and predictability and offers significant advantages over traditional mli and spray on foam insulation sofi.

Multi layer insulation nasa.

It was found that use of 2 mm foil spacing and locating the foils near the hot boundary with the top foil 2 mm away from the hot boundary resulted in the most effective insulation design. For example a 2 by 4 section of wall with fiberglass batting might have an r value of 11 to 15 while 7 layers of aluminum foil subdividing the space achieves a total of r 18. They can be used as guidelines for multilayer insulation design for future. Integrated multi layer insulation imli is a next generation ultra high performance thermal insulation.

In construction multi layer reflective insulation systems either achieve a higher r value for a more energy efficient home or allow an r value that matches local codes in a smaller space.
