Parafon® Decibel Barrier

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 Barrier is installed vertically in the plenum above the partitioning wall and reinforces effectively the sound insulation via the suspended ceiling. Can be used as a single or double in combination with Parafon Decibel sound insulating suspended ceilings. Decibel Barrier is manufactured in non-combustible stone wool and has an aluminium layer on the front and glass-fibre felt.
