WHISPER: Sound-Absorbing Panels

Whisper® is an innovative acoustic panel designed with honeycomb-like closed-cell structures for optimal noise absorption. Made from high performance polyethylene foam - durable material which remains acoustically ‘soft’ eliminating the problem of hard reflective surfaces that contribute to reverberation and echo.

Engineered to withstand challenging environmental conditions such as, water, moisture, humidity, dirt, dust, ultraviolet light, chlorine, and harsh chemicals. Whisper® offers unparalleled durability in demanding environments.

Whether you seek a high-performance acoustic solution that is both resilient and effortless to install, indoors or outdoors, Whisper® stands as the definitive choice.
