INTEGRITY® Aluminum Chimney Liner Systems

---

INTEGRITY® (formerly CHIM-LITE®) Aluminum Chimney Liner is flexible for use in lining or relining masonry chimneys. It forms an effective flue gas exhaust liner system for category 1 heating appliances. This liner may be used for venting natural gas and propane heating appliances listed for use with type B gas vents. 

INTEGRITY® Aluminum flexible chimney liner is manufactured from two layers of .0055, 3003 aluminum; making it 10-15% thicker than the other aluminum chimney liner produced today!  Our chimney liner profile and wall thickness combination create a chimney liner that will never separate. You may just mistake it for stainless steel! 

INTEGRITY® Aluminum fittings are also made of 3003 aluminum. Our kits contain NO galvalum or galvanized materials which can be prone to corrosion over time. It’s truly a carefree kit. Cheaper aluminum chimney liner kits contain these inferior metals and as a result will have to be replaced numerous times over the lifetime of the appliance.

INTEGRITY® flexible aluminum chimney liner is available in 3”-24” diameters for residential to commercial applications. In addition to being manufactured entirely from 3003 aluminum and 10% thicker, each INTEGRITY® Aluminum chimney liner kit is superior to its competition. Every aluminum chimney liner kit includes: a 25' or 35' coil of INTEGRITY™ Aluminum flexible chimney liner, flat top flashing, mortar collar, basic rain cap, aluminum pop rivets and liner coupling/guide cone. 

INTEGRITY® Aluminum chimney liner is also available in a 100' bulk coil for 3" and 4" diameters; ideal for installing collinear fireplace gas inserts where there is no need for the parts that come with a traditional kit. These are the perfect companions to the Homestyle Collection of specialty gas terminations for direct vent appliances.

Tested by Underwriters Laboratories (UL) to their stringent 441 standard. INTEGRITY® Aluminum chimney liner systems are tested and listed by Underwriters Laboratories, Inc (UL). UL developed the standard for testing chimney liners. That is why they are the test lab we chose to evaluate our INTEGRITY® chimney liners.

We are proud to manufacture every aspect of our INTEGRITY® chimney liner systems in the USA, while other companies only manufacture their chimney liner in the US and import their components from Canada, China and other foreign countries.
