Semi-rigid flexible duct, also known as semi-flexible duct, strikes a balance between rigid and flexible ductwork. It is more supportive than flexible ducting, reducing kinks or compression, yet more pliable than rigid ducts for easier installation in tight spaces without complex fittings. Made with reinforced design to maintain shape, it’s suitable for various HVAC applications requiring both rigidity and flexibility. Useful in residential, commercial, and light industrial settings, especially where space is limited, and minimal bending is needed without risk of damage.
