Acoustical Louvers

Noishield and Slimshield acoustic louvers from IAC Acoustics reduce noise pollution from plant cooling towers, boiler rooms, and air handling systems in all types of buildings, including power stations, chemical treatment plants and offshore applications. Our acoustic louver solutions from will help to combat environmental noise problems that affect mixed, commercial and residential areas. Our acoustic louver panels and acoustic grilles reduce noise from a wide variety of applications that include:

* Fresh air intakes for ventilation systems
* Mechanical equipment screens
* Noise attenuation solutions for roof top plant rooms
* Acoustic barriers and screens
* Process air intakes
* Cooling tower inlet attenuators and screens

Should none of our standard range of silencers meet your requirements we will develop one for you. If you have a special requirement, please contact us and our specialist team will be able to provide you with a bespoke solution. IAC Acoustics Duct Attenuator Range of Products.

We design and manufacture duct attenuators in response to specific requirements from acoustical consultants, consulting engineers, owners and contractors. Our duct silencers provide the most economical choice for solving the wide diversity of noise control problems encountered in HVAC engineering.

IAC standard rectangular duct attenuator cross sections range from 150mm x 150mm (6in. x 6in.) to 1200mm x 1200mm (48in. x 48in.). For small mains, branches and duct run outs there are module sizes to fit every need. When large silencer banks are required, multiple-module assemblies can be arranged to provide almost limitless dimensional flexibility.
