All About Lock-Top Chimney Dampers

Do you know energy dollars are escaping out of your chimney?

See why most dampers perform poorly and cost you money.

Cast-iron plate and frame do not seal tightly, allowing energy dollars to escape.

  • Traditional chimney 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 Lock-Top Energy-Saving Damper seals tightly to save you money.

  • Lock-Top's rubber gasket seals tightly like a storm door for your fireplace, and keeps heating and cooling dollars where they should your home.

  • Lock-Top mounts on top of your chimney to keep out animals and rain.

  • Lock-Top easily operates from inside your firebox and seals tight every time you close it- eliminating any draft.

Red, silicone rubber gasket under Lock-Top lid seals tightly to eliminate draft.

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

Keep heat and energy in...rain and animals out
If it's not the cold drafts on your feet, it's the high energy bills in your mailbox.

You've got a fireplace problem you probably don't know about. It's your chimney damper. It leaks. Not a lot mind you, but enough to be costing you over $200 a year in lost energy.

The Lock-Top Damper seals tight with a silicone rubber gasket
That's right, our damper seals with a rubber gasket, not metal to metal like your current damper. A Lock-Top Damper seals tight, so virtually no air, and thus no heat or air conditioning gets lost up your chimney.

The Lock-Top also eliminates downdrafts, seals out rain which can deteriorate the inside of your chimney, and prevents entry by pests like squirrels, raccoon, and nesting birds.

The Lock-Top mounts on top of your chimney
On top? Yes, that is the perfect location to create an airtight seal.

A cable drops down your flue and connects to a handle which mounts where you can reach it for convenient opening and closing.
