What is the difference between a stainless steel and a flexible liner?
A. A stainless steel liner is generally best for a masonry fireplace. Stainless steel is more durable, and a stiffer liner. This will be more expensive than a flexi-liner. Because it costs more to make, and it takes the technician longer to install. A flexi-liner is usually best for a pre-fab fireplace, and is more flexible than a stainless steel liner.
