Flexible duct insulation
Flexible ducts generally attach air outlets to rigid ductworks. The round ducts are composed of ISOVER glass wool sandwiched between layers of robust plastic or aluminium, with coil wires for rigidity.
They 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 2 m because of their basic level thermal and acoustic performance and the high pressure losses they cause. They are, however, very practical and easy to install.
