Flexible Ducts are used in heating, ventilation, & air conditioning (HVAC) systems to distribute air throughout a building. They are typically made of a flexible plastic material, such as PVC or polyurethane & are designed to be lightweight & easy to install. Flexible Ducts are ideal for use in situations where rigid ductwork cannot be easily installed, such as in tight spaces or around obstacles. They are also helpful when the ducts need to be moved or repositioned frequently.
