Our Flue Vent 180mm insert is an ideal product for capping older chimneys or flues that are no longer in use while still allowing airflow. The flu vent has a traditional red colour that smoothly blends itself in with roof tiles leaving a professional finish. Not to be used with active flues or fires. The Hepworth flue vent ventilation terminal is used to maintain airflow and prevent condensation within a redundant flue. It is an effective and simple solution to the structure of an unused chimney, requiring minimal alteration work. Colour resistant to fading Fits both new and existing chimney pots Resistant to frost Prevents birds from nesting in the flue Prevents rain from directly entering the flue
