An electrical insulating material
Insulation for houses and tents, reflecting thermal radiation
Five layers of metallized boPET film in NASA’s spacesuits make them radiation resistant and help regulate temperature.
Metallized film emergency blankets conserve a shock victim’s body heat.
As a thin strip to form an airtight seal between the control surfaces and adjacent structure of aircraft, especially gliders.
Light insulation for indoor gardening.
Fire shelters, used by wildland firefighters.
Proximity (aluminized) suits used by AR-FF fire fighters for protection from the high amount of heat release from fuel fires.
Aluminized boPET films are no longer used as thermal and acoustic insulation in aircraft since they were found to have been a factor in the Swissair Flight 111 crash. The accident investigation showed that the aluminum layer prevents the film from self-extinguishing in a fire under the conditions in aircraft.
Used in sock and glove liners to lock in warmth
