Wavebar^® dBX

Wavebar^® dBX is a high performance, flexible, mass-loaded, polymer noise barrier offering superior acoustic transmission loss. dBX represents the latest in alternative noise barrier technology using recycled polymers that are halogen-free. It was developed to meet market noise reduction requirements for the domestic, commercial, industrial, automotive and marine markets.

Wavebar dBX is available with a reinforced foil facing. This high performing product was engineered by Pyrotek to achieve a self-extinguishing, low smoke emission, thin, strong and highly flexible product. These properties, combined with foil facing, give dBX added strength, high transmission loss and fire rating, complying with IMO 653.16 marine standard, and building code for low spread of flame. The foil facing also makes it easy to bond onto other substrates using matching Tape ALR adhesive or equivalent.

Stiff lightweight panel constructions, such as plasterboard, drywall, plywood and hollow core walls, typically have coincidence dip resonance which allows noise to transmit through a construction. The coincidence dip is dependent on the material’s stiffness and thickness and occurs at the point where the sound transmitted through the structure matches the natural frequency of the panel.

dBX prevents coincidence dip resonance. The thin, dense mass barrier reflects and absorbs the transmission of sound through walls, ceilings and floors, reducing the critical frequencies generated from mechanical equipment, engine noise and electronic audio technologies such as radio and television.

dBX products are environmentally safe, contain no ozone-depleting substances and comply with European and Australian standards for Volatile Organic Compound emissions.

Areas of Use

• Marine engine rooms and deckheads to reduce noise transmission
• Rail carriages for under floor insulation to reduce track and braking noise
• Inside cavities or over lightweight wall, ceiling and floor constructions. Ideal for theatres, office partitions, meeting rooms and high privacy areas.
• Between the plenum chamber of a floor slab, roof and adjoining partition walls
• Acoustic doors to increase transmission loss
• Automotive cabin application to reduce engine and road noise transmitting through the structure
• Can be laminated onto lightweight structures to dampen and reduce airborne noise
• Usable where moulded parts or components are required
