This fireplace shutter completes the chimney channel, while warm air is distributed via gravitational or mechanical means. It is installed on the wall of the flue. The construction of the Luft shutter is characterized by the presence of a covered air duct. When installing the shutter, care must be taken to ensure the correct orientation. If you install the fireplace shutter, the air ducts should be at the bottom, while the intake should be at the top, ensuring sufficient circulation of warm air. The shutters are painted with powder that is known for its color and heat resistance. Additionally, the paint on the shutter protects against mechanical damage.
