flexible noise barrier
Wavebar is a high-performance, flexible mass-loaded vinyl noise barrier, offering superior acoustic transmission loss. Designed to meet market requirements it has been effectively used to reduce noise in building, commercial, industrial and automotive markets, globally.
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.
Our range of standard mass loaded vinyl barriers include ‘Wavebar®’, and ‘Wavebar® NC’ (Noise Curtain) with reinforced fabric backing offering strength and is self-supporting. The extraordinary strength of ‘Wavebar® NC’ with its versatility to hang or drape in long lengths favour its use as noise enclosures in industrial and construction sites.
dBX Flexible Noise Barrier with Aluminium Glass-Cloth Facing
Quadzero™ dBX is a high performance noise control product that exhibits superior transmission loss performance. It features a flexible, mass-loaded, noise barrier, laminated with an aluminium foil-covered glass-cloth facing, (AGC). It was developed to meet market requirements in marine, rail, domestic, commercial, industrial and automotive industries.
‘dBX’ is a thin, strong, highly-flexible mass barrier made from recycled polymers that are halogen-free and offered in a range of weights that provide impressive acoustic transmission loss performance. The aluminium glass cloth (AGC) face offers a durable, flame-retardant surface enhancing its fire and acoustic performance. This high-performing product complies with IMO 653.16 marine standard building code for low spread of flame and exhibits impressive transmission loss and fire performance.
Stiff lightweight panel constructions, including plasterboard, drywall, plywood and hollow core walls, typically exhibit coincidence dip – a phenomenon where there is a reduction in the noise-transmission loss. This can be affected by the stiffness, mass and natural frequency of the construction and occurs at a point called the ‘critical frequency’ where the frequency of incident sound matches the natural frequency of the structure.
Quadzero™ dBX’s flexibility alters the stiffness of the construction, thereby shifting its natural frequency and co-incidence dip phenomenon outside the ‘critical bandwidth’, and thus maintains the transmission loss performance of the system. The dense, mass-barrier attenuates noise from mechanical equipment, engine, and electronic audio technologies such as radio and television, when transmitted through walls, ceilings and floors.
lightweight multilayered acoustic panels
Subdue® is a lightweight multilayered 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 with a range of sound insulating inner core materials. 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.
