First-class strength – The thickness of the steel and the process of manufacturing make this chimney lining system the leader in strength and heavy duty.

If you burn wood or coal as your primary heating source, you’ll need your flue cleaned often and aggressively. Armor Flex™ is an effective solution.

The Armor Flex™ Lining System uses heavy duty certified stainless steel. Two types of stainless steel are used:

• 304L used exclusively for wood burning
• 316L useful for coal and is a good alternative for all fuels.
