Rainshield – Water Resistant Acoustic Foam

Rainshield – Water Resistant Acoustic Foam

Rainshield is a water resistant acoustic foam which uses a high performance honeycomb like structure to absorb noise. This durable material remains acoustically
‘soft’ eliminating the problem of hard reflective surfaces that contribute to long reverberation times and echo. If you have challenging conditions to deal with such as, water, moisture, humidity, dirt, dust, ultraviolet light, chlorine and harsh chemicals, then Rainshield water resistant acoustic foam is the right acoustic solution for you.

Rainshield is easy to fabricate, light weight, quick to install, and retains its structure in humid environments. Its superior noise reduction qualities are proven in some of the most rigorous applications, such as road and rail traffic and industrial machinery.

Rainshield sound absorbing panels help to safely reduce noise, make music sound better, allow people to speak and hear one another, and contribute to a safer and more productive work environment, indoors, or outside.

Rainshield uses a networked honeycomb like structure to absorb sound, providing unique properties over conventional fibre, polyester and open cell foams. The structural and acoustic properties of Rainshield are demonstrably maintained following exposure to moisture. Therefore, there is no need for a water barrier, protective film or perforated metal facing to ensure acoustic properties are maintained. It is free of Formaldehyde, has low volatile organic compounds (VOC’s), low particle emissions, is fibre-free, and has zero ozone depleting substances.
