Energy Innovator of the Year Award for 2014.
Here's what others are saying about the All Season Control Cover:
- I would like to nominate Denny Moore and Benson Energy for their All Season Control Cover. I have worked in the roofing industry for almost 20 years and observe closely the building envelope from the roof perspective. I have always been surprised by the open chimney tops that we encounter and the amount of air escaping them in in both the heating and cooling season. In winter months when we are working on homes with open chimney tops, we often utilize the heat escaping from them to thaw out materials, equipment, and frozen hands in order to keep working in the cold.
Although temporarily useful to us, the cumulative energy loss from decades of an open chimney are enormous and account for a good portion of energy loss in a home with these conditions. Summer months also cause loss, especially if there is a swamp cooler in use. The pressurization of the home will drive a cool stream of air out of the opening and we can find respite from the hot sun over an open chimney top.
We see some covers in use that are simply critter guards and still allow the air to escape but the ASCC can be easily opened for use or closed to keep critters out and energy in. It was exciting to find a solution that will help homeowners save a great deal of energy with a simple and cost effective chimney cover.

Benson Energy - Control Cover Damper
For over two decades, our company has turned to Benson Energy and the All Season Control Cover to provide custom solutions to problem chimney restoration projects. The universal hinge mechanism allows different sizes and configurations to be created to handle situations even where there is no existing flue tiles.
The Control Cover chimney-top fireplace damper is much more effective at conserving energy than even glass doors or existing in-throat traditional dampers. Glass doors are not sealed, so they leak, and worse, they block thermal radiation, and so lose much of the radiant energy of the fire. In-throat dampers are not airtight when new, and can quickly warp with high heat from fires, and eventually rust with incoming moisture and can become inoperable.
Sealing off the top of the chimney is also a safety precaution. Moisture mixing with creosote creates an acid that eats away the mortar connecting the flue tiles together over time. This destabilizes the physical integrity of the chimney and can even allow temperatures to rise to a combustion level outside the chimney lining.
Massive amounts of energy are lost each year through millions of uncovered chimneys, not to mention countless critter home invasions. The All Season Control Cover solves many if not all of the problems associated with wood burning masonry fireplaces.

- The Patent for the All Season Control Cover was cited as follows:
The sturdy construction of the hinge for the flue cover is an important feature of the invention... The sturdy construction of the side plates and hinge plates and the lack of any welded joints provides a hinge which is able to readily withstand the forces which are applied to it and the temperature changes to which it is subjected. At the same time, the hinge permits free opening and closing movement of the flue cover and allows the cover to seal against the flue in an air tight manner when closed.
An additional feature which is important to the invention is the use of a torsion spring to bias the cover toward its open position. The torsion spring is loaded in compression when the cover is closed and is considerably stronger than a tension spring. Therefore, the torsion spring is much less susceptible to being permanently set or to fail in fatigue due to repeated cycling. The torsion spring is also well shielded for the elements by the parts of the hinge mechanism which mounts the cover on the flue. The torsion spring typically lasts as long as the rest of the parts of the assembly and functions in a reliable manner to assure opening of the cover when the cable is released.
