DPR recently completed a project on a roof in Monk Bretton, near Barnsley. They were contacted by a customer requesting a new ventilation cowl to their existing chimney pot. A cowl is used to provide good ventilation and also gives added protection against wind and rain entry. They can also prohibit any animal entering the chimney whilst maintaining flue efficiency. DPR supplied and fitted a DFE terracotta clay ventilation cowl specifically for a gas fire flue. A terracotta cowl was recommended as it should last longer than a standard cowl and was in keeping with the current chimney structure and therefore more aesthetically pleasing.
