Noise Barrier

Noise barrier for road and housing.

Noise barriers Landscaped barriers, it is a mesh fence, placed between the sound source and the sound receiver. Highly decrease the sound effect among the sound receivers. Pattern: acr shaped or flat straight pattern. Height of noise barriers: 2000mm, 2500mm, 3000mm Standard space between the post:1000mm, 2000mm, 2500mm . Material of the noise barriers: metal barriers, punched hole metal mesh , frp noise barriers, etc Usage: railway noise barriers, highway noise barries, landscaped bariers, etc High-speed rail noise barriers: Size:l1960mmxw500mmxt140mm Post: h shape steel. L1960mmxw500mmxt140mm

Noise Barrier

Noise barriers supplied by Vinh Hung IP, which meet all current standards, are able to minimize the noise affecting surrounding area (residentialareas, hospitals, schools, industrial parks, etc.) and ensure a fine landscape. The noise barriers are windproof and aid to driver's concentration which could increase safety for people and other vehicles. PRODUCT CHARACTERISTICS Absorptive noise barrier: Using sound-absorbing materials, punch plates, etc., which prevent sound reflection. Sound absorption standard rating: Noise Reduction Coefficient NRC describes the average sound absorption performance of noise barrier. For the absorptive noise barrier, the NRC will be within 0.6 to 0.9 range (FHWA highway noise barrier design handbook). Reflective noise barrier: Using good noise insulation materials such as Polycarbonate panels (PC), Poly methyl methacrylate panels (PMMA), Glass laminate. Sound reflective standards: Transmission loss coefficient TL will measure the amount of sound energy hitting on or transmitted through the barrier. For the reflective noise barrier, the TL coefficient is >25 dB at 500HZ and >30 dB at 1000HZ (according to KS F4770 standard). INSTALLATION Preparation: Prepare installation materials, tools and equipment. Check the surface of base structure: - Check the distance among the anchor bolts. - Check the dimensions of posts flanges, positions of bolt holes and anchor bolts.

Metal noise barriers Material:galvanized plate, aluminium plate, color steel plate, iron plate, other Metal thickness:0.6mm, 0.7mm, 0.8mm, 1.0mm, other Finished thickness:50cm, 60cm, 80cm, 100cm, other Metal noise barriers can effectively decrease the high-frequency by10-15db. The installation of the metal noise barrier can be designed according to the distance between the sound source and the receiver.The sound can be belowed 6db by the height of the screen double. Metal thickness:0.6mm, 0.7mm, 0.8mm, 1.0mm, other Finished thickness:50cm, 60cm, 80cm, 100cm, other

Noise barriers products supplied to projects by Vinh Hung IP meet all the current standards, enable to minimize the noise volume affecting the surrounding area (residential areas, hospitals, schools, industrial parks and so on) and offer the beautifulness. The noise barrier walls are windproof, increases the concentration for drivers, which increases the safety for people and vehicles on roads Absorptive noise barrier wall: Using materials capable of absorbing the sound, punching plates and so on, which prevents the sound reflection. Sound absorption Standards: Noise Reduction Coefficient â?? NRC indicates the amount of noise power absorbed by the noise absorbing barrier wall. For the absorptive noise barrier wall, the NRC will be within 0.6 to 0.9 range (FHWA highway noise barrier design handbook). Reflective noise barrier wall: Using the good noise insulation materials like Polycarbonate panels (PC), Polymethyl methacrylate panels (PMMA), Glass laminate. Sound reflective Standards: Transmission loss coefficient â?? TL will measure the sound power hit on or transmitted through the walls. For the reflective noise barrier wall, the TL coefficient is >25 dB at 500HZ and >30 dB at 1000HZ (refer to KS F4770 standards). ALLATION METHODS Preparation: Gather materials, accessories and installation Check the surface of the basement system: Check the distance among the anchor Check the dimensions of post flanges, positions of bolt holes and anchor

ITLS-RB is a flexible high-performance sound barrier. It is a low-stiffness material which improves the sound transmission loss by effectively blocking noise. ITLS-RB has a reinforced backing to further enhance its mechanical strength. It is designed for hanging-up applications where the material is typical used as an acoustic curtain. ITLS-RB is a high temperatures resistant noise barrier. It provides excellent soundproofing effect at a wide range of temperatures, typically from -40°C to +140°C, where other traditional noise barriers would fail. ITLS-RB meets with GM Holden specification HN2483 requirements. Key Features *Durable & flexible *Suitable for hung-up applications *Easily cut, fabricated and installed *Contains no lead, non toxic *May be stapled or nailed into position *Suitable for elevated temperatures up to 140°C(Intermittent) Key Benefits *Proven soundproofing performance *Economical *Low installation cost *Easy to handle
