Applications

Flexible ductwork systems

Flexible ducts generally attach air outlets to rigid ductwork. The round ducts are composed of ISOVER glasswool sandwiched between layers of robust plastic, with coil wires for rigidity.


Isover Flexible Ducts

Flexible ducts are primarily used for attaching supply air outlets (diffusers and grids) to the rigid ductwork. In most cases, local regulations limit their length to a maximum of 1.5 m because of their base level thermal and acoustic performance and the high pressure losses they cause. They are, however, very practical and easy to install.

Examples of ISOVER solutions for this application include:
