Semi-rigid ducts are flexible, metal air ducts that can be bent to a specific shape and will hold that shape, eliminating the need for rigid elbows in many applications. They are more durable and resistant to crushing than flexible foil ducts, making them ideal for situations like dryer vents, where they allow for easier installation by letting you position an appliance close to the wall. Their construction, typically helically corrugated aluminum with a wire helix, provides durability, heat resistance, and the ability to maintain airflow efficiency.
Key features and benefits
- Flexibility and rigidity: They are flexible enough to be maneuvered around obstacles and into tight spaces, but rigid enough to stay in the position they are bent into, which simplifies installation and avoids kinks or crushing.
- Durability: Made from metal like aluminum, they are more resistant to puncturing and damage than flexible plastic or foil ducts.
- Improved airflow: Their construction helps them maintain a consistent diameter, which is more efficient and resists lint buildup compared to some other flexible ducts, leading to better energy savings.
- Heat resistance: The aluminum construction is highly resistant to heat, making them suitable for applications like dryer vents, kitchen exhaust, and industrial fume ventilation.
- Versatility: They are used for a variety of applications, including residential and commercial HVAC, appliance venting, and industrial fume extraction.
