System CW - Acoustic Data

Our Vinyl concertina system is designed specifically for low budget projects.
They do however come in three different levels of sound attenuation.

They are as follows:

• Type C15 can achieve 15dB RW
• Type C23 can achieve 23dB RW
• Type C30 can achieve 30dB RW

These sound attenuations are extremely good when taking into account how light weight this system is.

Please note that we are available to provide sound certificates upon request.
