Whisper®
Acoustic Baffles and Rafts for Ceilings

An ideal sound absorption solution for factories, hospitality, public buildings, recreation, construction, industrial enclosures and transport.

Whisper® is a closed cell polyethylene 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 reverberation and echo.

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

Whisper® 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.

VERTICAL HANGING BAFFLES

Hanging baffles are the most economic method of applying acoustic absorption to an interior space. Whisper® absorbs sound on both sides, therefore baffles enable minimum product for maximum absorption. As many as 16 baffles have been installed per hour on large builds.

 

CEILING RAFTS

Hanging panels are an economic method of applying acoustic absorption to an interior space. Whisper® absorbs sound on both sides, therefore baffles enable minimum product for maximum absorption. Ceiling rafts are a better option where total available height in a space is restricted or material use needs to be minimised for maximum acoustic performance.

  • Available thicknesses; 25mm, 40mm, 50mm
