Soundproof mat and soundproof material "CISILENT"

Easy and flexible noise control measures that can accommodate various conditions (patented).

As environmental awareness increases and it becomes clear that severe noise can harm health, effective measures are being sought. In places where traditional heavy and rigid concrete systems cannot be used, the lightweight and flexible CISILENT soundproof wall demonstrates excellent effectiveness. Even in cases with spatial and technical issues, weight restrictions, and other constraints, new possibilities open up both indoors and outdoors. CISILENT efficiently solves noise problems. It features a lightweight structure that can be installed in narrow spaces and is easy to transport. Its simple assembly allows it to be used as a temporary system. The transmission loss of the flexible soundproof wall CISILENT is Rw=25dB, meeting the requirements of the German guidelines for road noise barriers (ZTW-Lsw 88). Moreover, when comparing the weight per unit area, it is significantly lighter than traditional sound barriers. Even if bulk materials have the same mass per unit area as CISILENT, their sound insulation effect is inferior. This is because their high rigidity causes sound to hit the surface and diffuse again. In contrast, the flexible CISILENT exhibits sound insulation effects proportional to its mass.

basic information

CISILENT is a product of the German company CALENBERG. It is modular in design, allowing for tailored solutions to various spatial requirements. A flexible soundproof wall for outdoor use The textile, made of three layers of high-strength polyester fabric, is designed in a bag shape to allow for filling materials. The coating treatment makes it resistant to moisture, dirt, and microorganisms. The fabric can be printed on, making it ideal for advertising purposes. Filling media Even without any filling media, the cover alone already provides a transmission loss of 16dB. By filling it with media (flame-retardant soundproof wool), the transmission loss can be improved to 25dB. CISILENT can provide customized proposals according to your needs.
