Rigid chimney liners are non-flexible, straight pieces of 22 gauge (thickness) stainless steel that most commonly come in 4-ft sections. These sections have male and female ends which are screwed or pop-riveted together giving the liner smooth, snug connections. This type of chimney liner is completely smooth on the inside and will give you a 20% better draft than a corrugated or light-wall chimney liner. This is hands down the most durable stainless steel liner on the market today. It is also easy to clean after each heating season, and because of the additional draft, you will collect less creosote (if used for wood burning appliances). This option is also much less labor-intensive than our Cast-In-Place liner system, making this an ideal chimney liner, and Chimney Savers’ favorite to install for wood stoves and furnaces.
