Shutting Out Noise

INSUsound-xlo is a new-age sound insulation material.

HVAC equipment for a building is one of the major sources of interior noise, and this noise comes from the main fans, flow of air through the system, and flow through diffusers. Most sound or noise is generated via rotating equipment and air and fluid movement through ducts and pipes. This movement creates vibration and noise. In fact, noise is a key parameter in measuring comfort level provided by HVAC systems, in addition to temperature, humidity and indoor air quality. Control of HVAC system sound and vibration are of equal importance. Apart from causing discomfort to occupants, they create secondary radiation of noise from vibrating walls, floors, piping, etc. Therefore, installing a suitable sound-absorbing liner inside the air ducts is an effective way to reduce airborne noise and improve acoustics. INSUsound-xlo, manufactured by Supreme Industries, is an ideal product for sound insulation applications in HVAC ducts. It is non-fibrous, tri-dimensional chemically cross-linked fire-retardant foam, and provides excellent sound absorption characteristics ideally suited in duct lining application. INSUsound-xlo is a range of high-performance engineered open-cell XLPE foam specially designed for applications that require enhanced sound absorption properties. Due to its open-cell structure, INSUsound-xlo allows effective absorption of airborne sound across a broad frequency range. Its high air flow resistance offers beneficial sound transmission loss properties. Unlike conventional products, INSUsound-xlo does not disintegrate or particulate, thus making it suitable material for ´clean room´ applications. It is suitable in duct internal lining, plenum area lining, pipe lagging, gaskets, AC equipment insulation and room acoustics. It is ideal for shopping malls, multiplexes, airports, BPOs, gymnasiums, commercial complexes, conference rooms, offices and hotels, banquets, concert halls and many more other applications.
