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 sound barrier 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 has a lightweight structure that allows for installation in narrow spaces and easy transportation. It can be easily assembled, making it suitable for use as a temporary system. The transmission loss of the flexible sound barrier 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 conventional sound barriers. Solid components, even if they have the same mass per unit area as CISILENT, have inferior sound insulation effects because their high rigidity causes sound to hit the surface and disperse again. In contrast, the flexible CISILENT exhibits sound insulation effects commensurate with 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, made from a high-strength three-layer polyester fabric, is designed to be bag-like to accommodate filling materials. The coating treatment repels 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 provides a sound transmission loss of 16dB. By filling it with media (flame-retardant soundproof wool), the transmission loss can be improved to 25dB. CISILENT can offer customized proposals tailored to your needs.

Company information
We provide a comprehensive service from design to product supply for various types of frames (platforms - operation platforms, walkways, stairs, handrails, ladders, etc.) and piping support devices (pipe supports) for plants and factory equipment. In the design phase, we conduct structural analysis and strength calculations, as well as planning design and detailed work utilizing 3D CAD (including the creation of installation drawings). Additionally, we offer integrated manufacturing from primary processing to assembly, welding, and painting, all linked with 3D CAD. For piping support devices (pipe supports), we supply high-quality products that are mass-produced using streamlined production technology from our German partner, LISEGA, which boasts a top global market share. We maintain a stock of standard products at our domestic factory in Japan, enabling us to respond to short delivery times. 【Products Handled】 - Spring hangers and supports - Constant hangers and supports - Hydraulic snubbers (hydraulic dampers) - Rigid hangers - Pipe shoes and pipe saddles - Secondary steel materials for piping support (beams, brackets) - Operation platforms (platforms), walkways, stairs, handrails, ladders - Piping racks - Viscoelastic dampers - Spring-type vibration isolation devices (spring devices) - Tuned mass dampers
