Frequently Asked Questions

What is semi rigid radial ductwork?

Semi rigid radial ductwork is a flexible but structured ducting system used to move air between a ventilation unit and individual rooms. It is commonly used in MVHR, MEV and other domestic ventilation systems.
What is radial ductwork used for?

Radial ductwork is used to create individual duct runs from a manifold or distribution box to different rooms. This can help simplify the duct layout and support balanced airflow across the property.
What fittings are needed for semi rigid ductwork?

A semi rigid ductwork system may require manifolds, plenums, connectors, bends, sealing rings, clips, blanking caps and other accessories depending on the layout and installation.
What size radial ducting do I need for my system?

The required duct size depends on the airflow needed at each valve and the overall system design. Radial ductwork should be sized as part of the complete MVHR design rather than selected by room size alone.
Is radial or rigid ducting better for a new build?

Both can work effectively when correctly designed. Radial ducting is popular in new builds because individual flexible runs can make routing and system balancing more straightforward.
