This is the actual HeatShield repair of a damaged flue system.

Here in Cincinnati, when a chimney liner is in need of repair Heat Shield can sometimes be installed to resurface the chimney liner without having to install a stainless steel chimney liner which is more expensive. If there are missing mortar joints in the chimney, the HeatShield® Joint Repair System can be an option for repair. You of course must have a professional evaluate the integrity of the chimney to see if a HeatShield® repair is appropriate for your chimney.
