How to Install a Flexible Aluminium Duct
Installing flexible aluminium ducts is a straightforward process, but one that requires care. Ideal for air conditioning, ventilation, and HVAC systems.
Materials Required
- Flexible aluminium duct in the appropriate diameter
- Duct clamps or aluminium tape
- Aluminium connector/coupling (if required)
- Aluminium duct cover/rose for a neat finish
Step 1: Choose the Diameter
The diameter must match the equipment outlet. The most common sizes are 80mm, 100mm, 125mm, 150mm, and 200mm.
Step 2: Measure and Cut
Measure the distance between the connection points. Extend the compressed duct to the required length.
Step 3: Connect and Secure
Fit the duct into place and secure with a clamp. Use aluminium tape to seal all joints.
Professional Tips
- Avoid tight bends — each 90° bend reduces airflow by 10%
- Keep the run short and straight
- Use insulated ducting in areas with significant temperature differences
