Chimney Terms

Top-Sealing Dampers

A device installed at the top of a chimney for the purpose of sealing the flue shut when the fireplace is not in use. They are often used as replacements for throat dampers that are installed just above the firebox when a masonry chimney is built. Lyemance and Lock-Top top-sealing dampers are as much as 90% more efficient than throat dampers because they provide a silicone rubber gasket seal rather than metal to metal.

Stainless Steel Chimney Liner

Stainless steel pipe, either rigid or flexible, made for relining flues of masonry chimneys when the original clay liner has cracked or broken. May also be used to create a lining in a masonry chimney that was made without a clay liner.

Chimney Caps

Protective coverings for chimneys usually made of aluminum, galvanized or stainless steel, or copper. Most chimney caps have a mesh screening that serves the dual purpose of spark arrestor and barrier against animals. Chimney caps also prevent rain from entering the flue of the chimney.

Lyemance Dampers - The Whole Story

See why most dampers perform poorly and cost you money.
Traditional dampers are located in the "throat" of a fireplace. They are made of cast-iron and are housed in a low-tech frame work.
Cast-iron plate and frame do not seal tightly, allowing energy dollars to escape.
These cast-iron dampers do not seal well—they have a leaky, rough, metal-to-metal seal.
Recent lab studies have shown that even a new throat damper can leak up to $200 of heating and cooling a year. Imagine how much energy an old, rusted out damper leaks!

The Lyemance Energy-Saving Damper seals tightly to save you money.

Lyemance mounted on the top of the chimney.
Lyemance's rubber gasket seals tightly like a storm door for your fireplace, and keeps heating and cooling dollars where they should your home.
Lyemance mounts on top of your chimney to keep out animals and rain.

Lyemance easily operates from inside your firebox and seals tight everytime you close it—eliminating any draft.


Do you still need more convincing that the Lyemance Energy-Saving Damper is right for you? Here is a five minute video that demonstrates the differences we have stated above.
