Designed for HVAC professionals and serious DIY enthusiasts, this 3-meter Aluminium Semi Rigid Flexible Ducting is ideal for residential or light commercial ventilation systems requiring reliable, sag-resistant airflow. The product excels at maintaining its shape through tight bends, providing a durable and fire-resistant solution for connecting fans and vents; however, users should exercise care during installation to avoid puncturing the thin aluminium foil walls.

While it is fire-resistant, always check your local building codes and the dryer manufacturer's specifications regarding the use of aluminium ducting for lint-producing appliances.
It is primarily designed for indoor ventilation systems. If used outdoors, ensure it is protected from direct impact, debris, and extreme weather.
Use a 200mm rigid duct connector and secure both sides with high-quality metal jubilee clips and foil tape.
It is recommended to use tin snips or heavy-duty wire cutters to handle the structural wire within the ducting safely.
Aluminium ducting typically handles standard ventilation temperatures well, but you should refer to the specific heat rating documentation provided on the packaging for exact limits.
Ensure the duct is fully stretched and properly secured at both ends with tight-fitting jubilee clips; ensure no sharp bends are causing air turbulence.
Check the duct for kinks or areas where it has been crushed. Ensure the duct run is as straight as possible to minimize pressure loss.
Immediately seal the area with HVAC-grade aluminium foil tape, ensuring it is airtight to prevent air leakage.
For optimal results, ensure the duct is fully extended before measuring the required length to avoid excessive slack that can cause vibration. Use high-quality foil tape or jubilee clips designed for 200mm ducts to secure the ends to your ventilation housing or wall vent. When cutting the duct to size, use a sharp pair of tin snips to ensure a clean edge without tearing the aluminium. To maintain the system, periodically inspect the duct for any accidental punctures or loose connections, and avoid crushing the ductwork under heavy objects or sharp building materials.
