STRATOCELL WHISPER | Sound insulation panel
Sound insulation and sound absorbing panel in synthetic fibre
Ethafoam® Whisper™ is a closed cell polethylene foam which has cells that are subsequently opened through the manufacturing process resulting in a highly efficient sound absorbent material with unique advantages compared to other materials. One of the key features of Ethafoam® Whisper™ foam is the ability to remain almost unaltered when exposed to water or humidity, the product’s acoustic performance remains consistent. Testing of Ethafoam® Whisper™ foam was carried out at Instituto Giardani, Italy under the EN ISO 354: 2003 Measurement of Sound Absorption in a Reverberation room. In-house testing using Sealed Air own Impedence Tube takes place on a regular basis to qualify the acoustic performance on Ethafoam® Whisper™ foam.
