Nilan Soundflex

Flexible sound absorber that forms a simple and easy connection between the unit and the manifold boxes or duct system. It is also suitable to use between the unit and the discharge/outdoor air intake in order to block noise from the roof stack. 

The perforated, internal duct absorbs sounds that arise in the ventilation unit via the fans, and it is very efficient. 

The insulation protects the air in the duct from its surroundings. As a result, when cooled down, there is no condensation. The insulation itself is protected from erosion by a layer of film.
