Hepworth ventilation terminals are manufactured under a Quality Management system to BS EN ISO 9001.
Ventilation terminals work by allowing air to circulate into and out of redundant flues to reduce the build up of moisture and thereby reduce the possibility of condensation forming inside the chimney. They also reduce the possibility of bird and rainwater ingress.
