Slitrack - Sleeper Pads

Slitrack Pads

In order to increase the track vibration insulation and to improve the life of the ballast track, Whisper Acoustics has designed a range of pads, named Slitrack, to apply directly under the sleeper of the track both on ballast and concrete platform applications.

The Slitrack pads can be glued on the base and on the sides of the sleeper or they can be drowned during the casting of the sleeper in the concrete.

SlitrackThe particular structure of high density SBR rubber granules and fibres, gives to these Slitrack sleeper pads an excellent insulating capacity and a good mechanical protection effect of the ballast gravel.

The Slitrack range can be used with excellent environmental insulating results on Tramways and Undergrounds, and on rail Freight transport and/or High-Speed railways.
