Chimney Liners Stainless Steel Frequently Asked Questions

What makes a Lock-Top or Lyemance Damper a great energy-saving alternative vs. the original fireplace damper?

These two great top sealing dampers both seal with a silicone rubber gasket. When you close our dampers warm air is sealed in and cold air is sealed out. This tight-sealing gasket means our dampers will reduce unwanted heat loss by 90%. And, unlike replacement throat dampers, the Lock-top and Lyemance Dampers have a lifetime warranty.
