Chimney Damperin NJ
Chimney Damper in NJ. Traditional damper is 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 Fireplace 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!
