Parafon® Decibel Mute

Parafon Decibel is a series of suspended ceiling products with sound insulating and sound absorbing properties whose primary area of application is sound reduction between rooms in buildings where the intermediate walls do not extend all the way up to the floor. Parafon Decibel Mute is an acoustic tile developed for optimal sound insulation and sound absorption. It is useful when sound insulation is needed via suspended ceilings of up to Dn,f,w 54 dB . The tile has a core of non-combustible stone wool and a sound insulating membrane. It has been tried and tested in a Swedish accredited acoustic lab and is quick and easy to install. Supplied with A-edge in several different surface layers in white, black or an NCS colour of your choice.
