Wavebar^® Quadzero^®

Wavebar^® Quadzero is a high performance, foil-faced, mass-loaded vinyl noise barrier, offering superior acoustic transmission loss and low spread of flame surface covering.

Quadzero was developed to meet market noise reduction requirements in the domestic, commercial, industrial and OEM sectors.

To achieve this high performance, the Pyrotek engineering team developed Quadzero to be dense, thin, strong, tear-resistant and highly flexible. These properties give the product high transmission loss throughout the various weight ranges. It complies with British and International fire and building codes for low spread of flame. 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.

Quadzero prevents coincidence dip resonance. The thin, dense mass Quadzero 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.

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

Areas of Use

• Inside cavities or over lightweight wall, ceiling and floor constructions. Ideal for home theatres, office partitions, meeting rooms.
• Over roof joists to reduce aircraft, rail and traffic noise.
• Applied between the plenum chamber of a floor slab, roof and adjoining partition walls.
• Installed around the outside of metal air ducts to reduce noise break-out.
• Wrapped around noisy pipes, e.g. fluid or gas pulsation in chemical, petrochemical and waste water treatment plants.
• Wrapped around valves and fan casings.
• Automotive firewalls to reduce engine and road noise transmitting through the structure.
• Rail carriages for under floor insulation to reduce track and braking noise.
