Lyemance Energy-Saving Dampers

Lyemance Damper Lyemance dampers are an industry icon and may well be the most widely installed top-sealing, energy-saving dampers in America. Lyemance dampers have been manufactured since the mid 1970s and are the very first top sealing chimney damper in the industry.

Lyemance dampers are made with a silicone rubber gasket that seals them as tightly as a mason jar to prevent warm air from escaping up the chimney, saving households hundreds of energy dollars each year. Their indestructible cast aluminum frame will last a lifetime.

Lyemance dampers even include an easy open power level assist to assure proper operation no matter what the conditions.

Plus, their low profile is ideal for homeowners who want to maintain the authentic look of their masonry chimney.

Naturally, Lyemance dampers come with a lifetime warranty.
