AcoustaTherm™ is a patented triple layer thermal and acoustic shield constructed of aluminum and expanded foam, which is attached using push pins, projection studs, rivets, etc. AcoustaTherm™ is die cut, then stamped with an inexpensive plastic die, into its final shape. A temperature drop of 490°F across this material is typical, with a 1000°F source temperature and only a ½” air gap. Typical transmission loss is 45 to 50 dB at 2500 Hz and up.
