systems, attic systems, aircraft fuselage systems, space probe systems, and crawl spaces. Reflective thermal insulation can be used as a stand-alone product in many applications but can also be used in combination systems with mass insulation where higher R-values are required. Military applications Low emissivity coatings have found applications in stealth technology, reducing the thermal infrared emissions from military equipment in the short-wave, mid-wave and long-wave infrared portions of the electromagnetic spectrum.
