Stratocell® Whisper®

Sound Absorbing Polyethylene Foam

2 Stratocell® Whisper® Stratocell® Whisper® 3

Noise-Directive 2003/10/EC calls for action when sound levels reach over 80dB to minimise damage to hearing. An additional 170 million citizens are living in so-called “grey areas” where the noise levels are 55-65 dB(A), causing serious annoyance during the daytime.

WHAT IS STRATOCELL® WHISPER® FOAM? It is a closed cell polyethylene foam providing excellent acoustic properties. This material is easy to fabricate and install, and retains its structure in humid environments, which will save you time and money.

It’s superior noise reduction qualities stand up to the most rigorous applications, such as road and rail traffic and industrial machinery. The low frequency sound absorption is ideal for HVAC systems and transportation components as well as acoustical panels.

It has been estimated that between 17 and 22% of the EU population (or close to 80 million people) suffer from noise levels that scientists and health experts consider to be unacceptable, where most people become annoyed, where sleep is disturbed and where adverse health effects are to be feared.

THE PERFECT ACOUSTIC SOLUTION

SOUND ABSORPTIONBy absorbing noise rather than just reflecting noise back, Stratocell® Whisper® laminated PE foam is an excellent alternative to many noise barrier materials currently used. Stratocell® Whisper® foam exhibits some of the best sound absorbing properties available today.

MOISTURE RESISTANTOne of the key features of Stratocell® Whisper® foam is the ability to remain almost unaltered when exposed to water or humidity, the product’s acoustic performance remains consistent and there is no need for a water protection film.

Stratocell® Whisper® has superior sound absorption, making it the ideal choice for acoustic panels.
