Chicago Chimney Dampers
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.
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 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. It 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, raccoons and nesting birds.
The Lock-Top mounts on top your chimney
On top? Yes, that is the perfect location to create an airtight seal. A cable drops down your flue and attaches to a handle which mounts where you can reach it for convenient opening and closing. The Lock-Top II combines the energy saving features of the Lock-Top Damper with a special stainless steel chimney cap.This combo unit is a great option for those who want to prevent snow build-up on top of the damper, and to protect their chimney from rain, birds and animals.
Spider and Lymance
Traditional fireplace dampers leak. They leak a lot!! That costs you big money in lost utility dollars going up your chimney. The Lyemance damper eliminates 90 percent of 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.
The damper has a silicone rubber gasket that provides a solid tight-sealing protection, just like an old fashioned mason jar. The Lyemance replaces traditional throat dampers that are notoriously leaky and expensive. The damper handle is mounted on the side wall of the firebox and a quick pull on the handle causes the damper to open when you are ready to start a fire. A stainless steel cover can be installed over the damper for additional protection.
A Spider Damper is the ultimate replacement for worn out, warped and defective factory build zero clearance dampers. It is mounted at the top of the flue and recessed approximately 6 inches below the flue’s termination point. It is ideal for restoration projects where an exposed damper is objectionable. The stainless steel construction enables the damper to withstand repeated chimney fires. It is easily opened with a handle mounted on the side wall of the firebox. When in the closed position, it helps reduce airflow in and out of the chimney.
