Clay Chapman describes his installation of the All Season Control Cover on one of his projects featured on his website, "Hope for Architecture". 

He says, "The minimal design of the Control Cover damper is favored for many historical restorations because the simplicity of the mechanism is quite inconspicuous while still providing a product that performs the required service effectively."

The elegant and simple design of the All Season Control Cover makes installation easy. The cover when closed is almost invisible from street level, so it doesn't detract from the aesthetics of the chimney. It's careful engineering makes it functional and efficient, providing energy savings and improving chimney performance.
