8 Inch DuraPlus Galvalume Wall Thimble

Galvalume Wall Thimble, 8 in. This fits between standard wall studs. This allows you to alter the wall thickness from 4 1/4" to 7 1/4". The revolutionary triple wall structure improves stove efficiency by keeping things warm inside and cool outside. As a result, both the building and the chimney are covered by a fire-resistant framework. The triple wall chimney has two layers of insulation. These solutions are designed to meet the stringent criteria of continuous gas ventilation while also improving safety.
