What is HeatShield®?

A faulty chimney liner makes it impossible for your family to safely enjoy and use your chimney system. There are options for relining your chimney system, such as stainless steel liners. However, if you want to repair your damaged clay tile liner, HeatShield® is oftentimes far and away the top option. It is a cerfractory flue sealant that can repair your clay tile liner in three different ways.

  • Joint Repair – The joints are mortar areas that hold the chimney liner together. Over time, they can deteriorate, crack, and suffer damage due to the constant exposure to high temperatures and other byproducts of fire. As they deteriorate, they create a fire hazard because they allow embers to come into contact with flammable materials within the walls surrounding your chimney. In addition, they can allow hazardous gases, such as carbon monoxide, to escape the chimney, exposing your family to serious health hazards. If our professional technicians notice any damaged joints during an inspection, they can apply HeatShield® and use a foam applicator to spread it over the area and seal any damage.
  • Resurfacing – We can also resurface the entire chimney liner with HeatShield®. This is recommended when the damage is more rampant and affects the majority of the liner. During resurfacing, we start by creating a custom-fitted applicator plug. The plug is used to apply a prep coat to remove any dust and debris. Next, we apply the HeatShield® Flue Sealant to smooth the entire flue surface and cover up any cracks or holes.
  • Relining – If your chimney system is damaged beyond repair, we can use HeatShield® to reline the system. To start, we prep the flue and apply the sealant, bottom to top. Once the sealant is dry, we fit a ceramic and stainless steel mesh liner into the flue and apply the sealant again to insulate and seal it even further. This provides more support, while protecting your chimney from the hazards of high temperatures and byproducts of fire.

All three options provide 20 years of guaranteed service!
