Parafon® Decibel Light

Parafon Decibel is a series of suspended ceiling products with soundproofing 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 Light has a core of non-combustible stone wool and an aluminium membrane at the back and satisfies the lower requirements on sound insulation via the suspended ceiling. In combination with Parafon Decibel Barrier installed vertically in the plenum, or the sound absorbing Parafon Bass placed on top of the suspended ceiling, the sound insulation with Decibel Light can be reinforced significantly if required. Supplied in several different surface layers in white, black or an NCS colour of your choice.
