Designed only for use with Flexi-Liner, this 10' long, high temperature, poly-faced Flexi-Sleeve adds extra protection to your chimney liner. There are four situations when this sleeve will be a great help to you: when the flue gas temperature is below 280 degrees Fahrenheit at the thimble, when large portions of the chimney are located at the exterior of the house, when the liner is venting fan-assisted appliances, and when the flue cavity is much larger than the liner. This sleeve is designed for 5.5" or 6" pipe.
