Flex King Pro Insert Kit

Chimney Insulation Kits help ensure safety and efficiency for stainless steel chimney liners. Chimney liner insulation will help keep flue gasses warm and reduce creosote buildup. Insulating your chimney liner is always beneficial, but typically required for wood burning applications.

We offer different types of insulation to cater to your chimney liner installation. The most common installation requires our Insulation Blanket Kit. However, if there isn’t enough room to install the Blanket Kit, take a look at the Insulation Mix.
