Industrial Quilted Fiberglass Absorbers are soft, porous, open-celled materials used to reduce the reflection of sound waves. As a result, reverberation time and ambient noise levels are also reduced, thereby improving communication in a variety of applications.
Applications
Commonly used in manufacturing spaces as wall panels, ceiling baffles, banners or ceiling clouds.
Sizing
All curtains are custom made with standard sizes of 48" x any desired length up to 50' with up to a 4" thickness. Custom curtain sizes and bound or unbound rolls are also available.
Easy Install
Wall panels are constructed with all edges bound and grommets across the top for easy installation.
Acoustical Performance
QFA products can offer up to an NRC of 1.05, helping to contain noise to its source and improving the overall acoustics of a space.

Decibel Examples
When trying to enclose a piece a machinery, most people will know they want it "quieter," but can't put into acoustical terms the end result (or decibel reduction) they want to achieve. With our audio examples, you can actually hear the decibel differences compared to static pink noise.
Pink Noise
An example of a randomized static pink noise. Pink noise uses deeper sounds and lower sound waves.
3 dB
Just perceptible. 3dB reduction has a 18% reduction in the perceived volume and yet is just barely perceptible to the human ear.
6 dB
Noticeable. 6dB reduction has a 34% reduction in the perceived volume and is very noticeable to the human ear.
10 dB
Double/Halving. 10dB reduction has a 50% reduction in the perceived volume and sounds half as loud to the human ear.
20 dB
Much more/less. 20dB reduction has a 75% reduction in the perceived volume and most noticeable to the human ear.
