The selection of air ducting is critical to the long-term effectiveness of any mechanical ventilation system, particularly those installed under the stringent requirements of UK Building Regulations. Our Round PVC Air Ducting is engineered to simplify compliance and ensure optimal system performance, directly addressing the key requirements of Approved Document F (ADF).
Optimising for ADF (Ventilation) Compliance
Approved Document F (ADF) mandates that ventilation systems must be installed and commissioned to deliver the design flow rates (as required by the system design and calculated under BS 5925 or BS EN 15251). This is where the choice of ducting material and shape becomes paramount.
Round ducting, such as our PVC range, inherently offers superior airflow performance compared to rectangular or oval alternatives of equivalent cross-sectional area. This is due to the maximized internal volume-to-surface-area ratio, which significantly reduces resistance and pressure drop.
