Use this metal storm collar when installing a through-the-roof roof with roof flashing. It is feasible to develop a fire-safe architecture that safeguards the chimney and the building thanks to the inventive triple wall structure, which is designed to keep things cold on the outside and bring hot breezes inside to increase stove efficiency. The triple-walled chimney has two levels of insulation. An air pocket and a ceramic blanket are used to secure the pattern.
