WAVEBAR - Flexible noise barrier The easy way to reduce noise through walls, floors and buildings near airports; as strip curtains, soft machine enclosures and truck mats; and for muffling explosions and noisy equipment such as jack hammers, drill rigs and pile drives. Made of special barium-loaded material, Wavebar is very flexible and easy to install even in and around awkward places or drape - or join into mats and enclosures - to greatly reduce noise transmission. A variant, Wavebar Quadzero, is manufactured with an aluminium finish. Features and benefits Wavebar ... is easy to cut and fabricate around pipe penetrations, ducting and cabling boasts high tensile strength is highly resistant to tearing is highly chemically resistant to oils, alkalis and acids enables unusually long vertical drops, providing an economical noise-barrier system even where space is limited comes in weights of 2, 4, 6, 8 and 10 kg/m² in its Wavebar Quadzero variant, is suited to joining with aluminium-reinforced tape thereby eliminating the need to use adhesives or mechanical fastening. Applications Wavebar is ideal for: shutting traffic and aircraft noises out of offices and homes portable screens use in partitioning under floor above false ceilings soft enclosures for fans and machines strip curtains use as a sound barrier against the noise of jack hammers, drill rigs, blasting and pile drivers. truck and bob-cat mats. Specifications Construction: 100% polyester fabric & barium loaded vinyl Weights: 2, 4, 6, 8 and 10 kg/m² Roll widths: 1350mm Roll lengths: Up to 20 m Roll weights: All rolls exceed 30 kg and must be handled by at least two people Specific gravity: 2.2 g/cm³ Flammability: Self extinguishes on removal of flame. Also meets the "Four Zero" early fire hazard index laid down in AS1530.3 (1989) - Simultaneous determination of ignobility, flame propagation, heat release and smoke release, which is a requirement under the Australian Building Code. Sound transmission loss: Achieves Rw 30 with a CAC (ceiling attenuation class) of 50 in a single flexible layer as determined by independent tests conducted to AS1191 Acoustics - method for the laboratory measurement airborne sound transmission loss of building partitions by National Acoustic Laboratories. Installation Step 1: Assess the area where the baffle is to be fixed. Make sure the ceiling slab is level when fixing the C-track or timber batten. If the slab is not level, fill the area with a caulking compound. Step 2: Cut Wavebar to fit. To do this, first measure the height between the ceiling and the ceiling slab (h). Add the width of the C-track or batten and add a minimum of 250mm for the ceiling overlap. Thus, in the schematic, the length (L) you would need to cut is given by L=h+100+250. Step 3: At joins, overlap Wavebar at least 50mm. Join the overlap with screws at 100mm intervals. Alternatively, if using Wavebar, use 75mm wide reinforcing tape to join the overlap down the full length of the drape. Step 4: For pipe, cable and ducting, measure and mark out the appropriate diameters or other dimensions and make incisions in the Wavebar to allow the obstructions to pass through. Using Wavebar for this work is recommended because of its ease of tapping.
