In addition to its entirely functional form and this offers a stylish black finish. The inventive triple-wall structure increases stove efficiency by preserving a cold climate outside and a warm atmosphere within. As a result, the building and chimney are both protected by a structure that is fire-safe. An air gap and a ceramic blanket offer protection. Ceramic blanket insulation reduces hot spots, which are frequent with loose-fill types of insulation, by being firmly held in place.
