Silent Plus

Noise barrier gabion with sand core

Silent Plus is a multi-chamber basket system consisting of the locking rod system monotecR®

  • Combining attractive privacy measures with highly effective noise protection.

Thanks to the incorporation of a fleece sack in the middle chamber, which is filled with sand, a seamless construction acoustic insulation layer is guaranteed.

By filling the outer chambers with coarse rocks, sound absorbing properties are achieved. In the case of more stringent requirements, the outer chambers can be filled with porous lava rock. This helps to achieve a higher absorbency.
