5.5 Inch Pre-Insulated Double Ply Smooth Round Chimney Liner Kit

The 5.5 Inch Pre-Insulated Double Ply Smooth Round Chimney Liner Kit is a premium stainless steel chimney liner designed for maximum performance and durability. Made from high-quality 316 stainless steel with built-in insulation, this liner kit is ideal for relining masonry chimneys while protecting against corrosion, moisture, and flue gas leaks.

This 5.5 inch pre-insulated chimney liner kit is commonly used for wood stoves, fireplace inserts, and other residential heating appliances that require slightly more venting capacity than a standard 5" liner. The pre-insulated design eliminates the need for separate insulation wrapping, saving time during installation while ensuring proper clearance and improved safety.

The double-ply smooth wall construction significantly improves draft efficiency and airflow compared to corrugated liners, while also making cleaning easier. This design provides superior strength and durability while maintaining flexibility for installation in masonry chimneys.

Pre-insulated chimney liners provide a convenient, all-in-one solution for installations where insulation is required, ensuring code compliance without additional materials or labor.
