SKU: The Top Damper Plus
DESCRIPTION: The Top Damper Plus combines the efficiency of The Top Damper with the added protection of a stainless steel cap. This damper still seals out rain, snow and sleet while sealing in "paid" heat and air conditioning, but also provides added animal and debris control. What makes the Top Damper Plus so unique is the soft, pliable rubber gasket seal attached to the frame that compresses and conforms to the lid when closed, while also acting as a chimney cap. Designed with a cast-aluminum lid and stronger spring, this damper is easier to open and close while still creating an air-tight seal at the top of the chimney. When closed, this damper is a great solution for saving “paid” energy dollars for homes with leaky or missing dampers. Heat loss up the fireplace chimney accounts for an average 8% of your home heating costs - The Top Damper Plus helps prevent this heat loss.
  • Stainless Steel & Aluminum Construction
  • No Fusible Link / Quick & Easy Install

The Top Damper Plus - Designed by Sweeps, Designed for Sweeps


U.S. Fireplace Products and Lindemann Chimney Supply are proud to offer our line of top sealing dampers! These high-quality dampers are designed by professional chimney sweeps and guaranteed to provide an energy efficient and cost-effective option when sealing the top of your chimney.


A chimney without a cap allows moisture from rain and snow to be absorbed into your the inner flue tile, outer bricks, and mortar. When this trapped moisture goes through a freeze/thaw cycle the integrity of the chimney’s structure becomes compromised, creating a safety hazard. Home heating and cooling costs can escalate when a proper damper is not installed, allowing air to escape through the chimney flue. At the same time, wildlife, insects, and debris can create further hazards inside an uncovered chimney flue.


What makes The Top Damper Plus so unique is the soft, pliable, rubber gasket seal attached to the frame that compresses and conforms to the lid when closed and also acts as a chimney cap. Designed with a cast-aluminum lid and stronger spring, this damper is easier to open and close while still creating an air-tight seal at the top of the chimney. When closed, this low profile damper is a great solution for saving “paid” energy dollars for historical homes with leaky or missing dampers. Heat loss up the fireplace chimney accounts for an average 8% of your home heating costs - The Top Damper Plus helps prevent this heat loss!


The Top Damper Plus are made for use only with open, wood burning, masonry fireplace chimneys and are not suitable for use on chimneys serving vented gas logs. Vented gas logs require the fireplace damper to be removed completely or fixed to a permanently open position; this is to assure that soot, fumes, and carbon monoxide do not enter your home. Use this damper only on vent-free gas logs if approved by the appliance manufacturer and the local authority having jurisdiction.
