Quadzero NL

fire-resistant, foil faced flexible noise barrier

Quadzero™ NL is a high performance foil faced mass-loaded vinyl noise barrier offering superior acoustic transmission loss and upgraded fire resistance.

With a fire-resistant foil facing, Quadzero™ NL was developed by Pyrotek to meet stringent fire safety requirements in the marine, building and transport sectors. The product achieves the highest fire ratings complying with International Marine Organisation standards for low spread of flame, as well as British, German, American and Australian building and transportation standards for heat release, toxicity and flame propagation properties.

The upgraded fire safety provided by Quadzero™ NL is offered without reducing the strength, tear resistance or flexibility offered by the Wavebar® Quadzero™ product range.

Stiff lightweight panel constructions, such as plasterboard, drywall, plywood and hollow core doors, 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™ NL shifts the coincidence dip to frequencies limiting its impact, thereby maintaining the performance of the product. 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 devices.

Quadzero™ NL contains no ozone depleting substances and complies with European and Australian standards for Volatile Organic Compounds emissions.
