TreDo

COMPACT, IMPACT SOUND INSULATED SHEAR FORCE TRANSMISSION FOR HIGH LOADS

The TreDo is a compact solution for the sound decoupling of landings and flights of stairs. The combination of a sound decoupling element (elastomeric bearing and dowel) and a simple shear force dowel sleeve (DB-N) impresses with good sound reduction via approved elastomeric bearings as well as high transmissible forces. The system can be extended with additional bearing elements, allowing loads to be supported in up to two directions.
