SONODEC Classic

Sonodec 25 is a flexible insulated duct consisting of a perforated aluminium/polyester laminate inner duct, thermally and acoustically insulated with a glass wool blanket and protected by an aluminium laminated outer jacket. A plastic barrier between the duct and the insulation prevents the diffusion of glass wool particles into the airflow.

Sonodec 25 is designed to provide both thermal insulation and sound attenuation, making it suitable for a wide range of ventilation and air conditioning applications.

Applications:

• Air supply systems
• Air conditioning systems
• Prevention of condensation in air conditioning systems
• Reduction of engine and equipment noise
