Quilted Fiberglass
Absorbers
|
dB Engineering Quilted Fiberglass Absorbers are fire safe, high performance
acoustical fiberglass blankets that are used to reduce reverberant (reflected) airborne
noise energy in many diverse industrial and architectural applications as well as on
original equipment.
They are available as overhead sound absorption baffles, wall
panels, in roll form with edges bound or unbound or as die-cut pieces. An excellent
alternative to urethane foams since they are fire safe, exhibit low smoke emissions and
possess high mechanical strength. Additionally, they have a wide range of
temperature limits, can be cleaned, and are unaffected by moisture, humidity, dust, dirt,
oils and most chemicals. Flexible quilted absorbers are easily installed, will not
degrade and have extremely long service lives.
