The flexible duct, thermally and acoustically insulated, thanks to its temperature resistance up to +250 C and non-flammability, is designed for transporting hot air, e.g. in DGP systems. Perforation of the internal duct reduces the noise generated in the installation and dampens its vibrations.

The inner layer of the cable is a slightly perforated duct. The insulating coating is mineral wool, while the outer layer is a multi-layer coating of laminated aluminum reinforced with glass fiber. The cable also contains a vapor barrier layer of polyester film between the inner cable and the insulation. Thanks to a thicker layer of aluminum, the duct has greater rigidity, durability and mechanical resistance compared to a traditional flexible duct.
