Texoflex Black Combi is a lightweight and highly flexible air duct. The duct is not insulated. It contains a steel spiral inserted in-between the layers of the duct. On the outside an extra PVC layer provides additional protection to the duct. 

This kind of flexible duct is very convenient for attaching air supply outlets or their plenum boxes to the rigid ductwork. The flexible duct can be attached with long zip ties or metal band clamps, and for extra strength Alu tape can be applied. 

However, please note, that the pressure loss is higher than for most other types of ducts. As such, designers and installers attempt to keep their installed lengths (runs) short, e.g. less than 5 meters (15 feet), and try to minimise turns. Kinks in flexible ducting must be avoided at all cost. 

Flexible ducts can tolerate a moderate negative pressure, however many designers prefer flexible ducts only for short distances, or in case of longer distances only for positive pressure applications. This is the case for air supply, but also if air exhaust is achieved in combination with, for example, a wall mounted fan or inline fan in front of the flexible duct. A typical use case is a fan located in a bathroom, toilet, or laundry room etc. blowing air downstream into the flexible duct towards the outside wall grille.
