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

In stock

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.

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 rubber gaskets of a Lyemance damper seal tightly like a storm door for your fireplace, and keep heating and cooling dollars where they should your home.

Lyemance dampers mount 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.

NOTE: Do Not Use With Gas Log Sets

A Lyemance Chimney Top-Sealing Damper will change all that. This well constructed, superbly engineered damper eliminates 90% of the winter heat and summer cooling loss that leaks past your current damper. It also eliminates downdrafts and keeps moisture and animals out of your chimney and home. Moisture in your chimney causes unwelcome odors and leads to deterioration of bricks and mortar. The Lyemance Chimney Top-Sealing Damper works year round to protect your chimney. That's why thousands are installed each year.

Our silicone rubber gasket provides solid, tight-sealing protection 
Nothing seals like a rubber gasket. That's why we use rubber enhanced silicone for lifetime durability. It makes the Lyemance Chimney Top-Sealing Damper seal super tight, just like an old fashioned Mason jar. Traditional throat dampers only give metal to metal contact - notoriously leaky and expensive. Who can afford heated or cooled air going out their chimney?

Your current throat damper was designed for the days when energy was cheap. Back then if you lost some energy here and there, it was no big deal. Today it is a big deal. Energy prices have skyrocketed and are predicted to go even higher. Lyemance dampers solve your problem because they seal like no throat damper can.
