A twin wall open terminal is the final element of a twin wall flue system, acting as a chimney cap. It's designed to provide an unrestricted discharge of flue gases into the atmosphere while protecting the insulation inside the twin wall flue. These terminals are fixed to the top of the flue system with a locking band. They help prevent wind from affecting the draft in the chimney and ensure the proper functioning of the appliance.
