Structure-born noise isolation



Vibration damping


VIBRAX-STAIRTOP SL is a shear pin for low to medium forces, which is used to connect and positionally secure concrete structural elements. The elastomeric coating that is vulcanised onto one end reduces the transmission of structure-borne noise. The pin can be used in all structure-borne noise-damping joints. An installation sleeve, for use e.g. in the case of prefabricated structural elements, is also available.
