Sonodec 50 TRD
The Sonodec 50 TRD consist of a perforated aluminum inner duct, thermical insulated with a glass wool layer and provided with an aluminium laminated outer jacket. An barrier between the duct and the insulation wool adds strength and prevents the diffusion of insulation particles as well as the following functions: improves acoustical performance, avoids cold bridges, leakage, pressure loss, protecting the R-value to be effected by humidity influences and avoid grow of fungus in the insulation wool. Both ends are taped to make ready-made connections.
The Sonodec TRD has an increased insertion loss, the Sonodec GLX however, has an increased sound attenuation.
application
- air supply systems
- air conditioning systems
- sound attenuator
- the reduction of noise from machines
