Soundproof screens

In high-noise production facilities, noise-reduction measures are essential to ensure compliance with required noise levels in the surrounding area. Back-draft silencers offer a particularly effective solution for this purpose. Based on acoustic engineering reports, attenuation values and permissible pressure losses are precisely determined, allowing the number, size, and performance parameters of the units to be accurately designed at the factory. In combination with natural supply and exhaust air systems, the silencers enable energy-free ventilation without disruptive noise escaping to the outside. Professional integration into the building structure is handled by INDU LIGHT’s engineering team.

The torsion-resistant, galvanized steel sheet housing serves as a sturdy base for the sound-absorbing panels. These panels are designed for optimal airflow and filled with moisture-resistant, rot-proof rock wool (building material class A1 according to DIN 4102). The glass fiber fabric laminated on both sides provides a tear- and abrasion-resistant surface that withstands air velocities of up to 20 m/s. For areas highly susceptible to contamination, a particularly robust perforated sheet metal version can be used. The maximum operating temperature is 100 °C.

The silencers are installed directly on the unit inside the building as an add-on to INDU LIGHT ventilation systems. They provide immediate sound-dampening effects that last indefinitely without incurring additional energy costs. Only in cases of heavy soiling is it recommended to occasionally clean the perforated metal panels to ensure long-term performance.
