NOISE CAN BE ANNOYING

Just make it Whisper®

Whisper® Acoustic Panels

According to the World Health Organisation, Noise pollution is a major environmental issue, second only to air pollution. Excessive noise can trigger stress responses, impacting our physiological and mental health. Noise is becoming a part of our lives that should not be overlooked.

If you have challenging environmental conditions to deal with such as, water, moisture, humidity, dirt, dust, ultraviolet light, chlorine, and harsh chemicals, then Whisper® Acoustic Panels are the right acoustic solution for you.

Whisper® Acoustic Panels are a honeycomb-like matrix of networked closed cells which efficiently absorb noise. Made from high performance polyethylene foam, this durable material remains acoustically ‘soft’ eliminating the problem of hard reflective surfaces that contribute to reverberation and echo.

With a strong yet light structure, Whisper® Acoustic Panels are easy to install and can be hung as baffles, attached to walls, and easily shaped for an attractive, creative solution to sound absorption. The material is fibre-free, doesn’t crumble or emit irritating dust or corrosive gasses, plus it is washable and resistant to common household cleaning chemicals.

For acoustic experts, Whisper® FR 50mm attains Class A Absorption, with an SAA of 0.98, and transmission loss Rw of 13.8 at a mass of only 1.25kg/m2.
