Stratocell® Whisper®

Stratocell® Whisper ® is a range of closed-cell semi-rigid sound-absorbing polyethylene foam sheets. The sound-absorbing properties make it one of the most innovative materials for industrial and building acoustics control. Thanks to the numerous certifications, it can be used in the construction, industry, railways, automotive, electronics, nautical, canalization and air conditioning sectors. Suitable for application in public buildings such as canteen halls, gyms, classrooms, shooting ranges, work environments, but also for the creation of road barriers, filtering systems, engine compartments and much more is also indicated for use in wet environments due to its?water resistance. The closed cell structure, the high level of sound absorption, its resistance to water and humidity, the self-supporting capacity, as well as the specific certifications for many sectors, give uniqueness to this innovative material.
