Mass Barriers

Subdue

Subdue composite acoustic panels
Subdue's innovative engineering and material process uses a unique combination of viscoelastic cores, lamination technology and outer layer materials to produce high performing composite panels at lower weights. An improvement over conventional manufacturing techniques, these panels now maximise noise reduction (STC rating) and effectively reduce the transfer of vibration (dB/sec decay rating) throughout the structure.

Subdue^® is a lightweight multi-layered panel offering exceptional acoustic properties. The outer layers of the sandwich panel are constructed from a choice of lightweight but rigid and strong high-quality materials, such as plywood, glass- reinforced plastic or metals, with a range of sound insulating materials as inner cores. Subdue was developed to meet noise reduction requirements in marine, rail, industrial and OEM markets. The panels are specially designed to optimise acoustic solutions at lower weights and are an ideal choice in weight-sensitive applications where strength and good sound insulation properties are required. The panels can be supplied in standard or custom-designed modular sizes for ease of installation, offering labour, cost and time savings.

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

Wavebar Original

Wavebar® is a high-performance, flexible mass-loaded vinyl noise barrier, offering superior acoustic transmission loss.

Wavebar was developed to meet market requirements for reducing noise in the domestic, commercial, industrial and automotive markets.

To achieve this high performance, the Pyrotek engineering team developed Wavebar to be dense, thin, highly-flexible, tear-resistant and strong. These properties give the product high transmission loss throughout the various weight ranges.

Wavebar Outdoor

Wavebar® Outdoor is a high performance, flexible, tough, mass-loaded vinyl noise barrier curtain offering superior acoustic transmission loss. It was developed to meet market requirements in reducing noise on construction and industrial sites.

To achieve its high performance, Pyrotek engineered Wavebar Outdoor using a tear resistant, high tensile strength tarpaulin base fabric to give added support and weather resistance for both indoor and outdoor applications.

Typically, Outdoor can be designed as partial or complete enclosures around noise sources to reduce noise transference.

Outdoor can also be laminated to Sorberfoam™ or Sorberpoly™ to create a curtain that will reflect and also absorb noise within an enclosure. It can easily be cut and fabricated into various shapes to suit any design or area.

The extraordinary strength of Outdoor provides the versatility to hang or drape in long lengths, with the attachment of velcro seals to create easy accessibility to the enclosure.

Acoustic curtains are especially useful around industrial equipment and building sites, since curtains offer more versatility and economy than rigid installations.

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

Areas of Use

• Both indoor and outdoor applications
• Around construction sites to reduce environmental noise issues
• Acoustic expansion joints to reduce break-out noise in air conditioning duct systems
• Portable acoustic curtains and screens. Easily draped over fencing to create an acoustic barrier
• Enclosures for industrial equipment such as punch presses, blowers, drop saws, granulators and generators
• Ideal noise curtain for portable mobile equipment including jack hammers, drilling rigs and pile drivers
• Can be designed to be installed into a C-track support system for moveable / concertina curtains
