The Butterfly Cap-Damper merges the functionality of a traditional damper with the protection of an exterior chimney cap. Its innovative dual-blade design provides precise control over airflow while sealing the flue from moisture, debris, and downdrafts when not in use. At Chicagoland Fireplace & Chimney Restoration, we install butterfly-style cap-dampers built from premium stainless steel for long-lasting performance and dependable weather resistance.
Unlike standard chimney caps or dampers, this design performs both functions simultaneously. When open, the butterfly mechanism allows clean, even exhaust flow to prevent smoke backup and ensure efficient combustion. When closed, the damper blades seal tightly against the cap’s gasketed frame, blocking heat loss and preventing cold air or rain from entering the flue. The result is year-round efficiency and a cleaner, safer chimney system.
Each unit is fabricated from heavy-gauge 304 stainless steel, chosen for its strength, corrosion resistance, and ability to handle extreme temperature swings. The precision-hinged butterfly plates and reinforced cap housing resist warping and degradation over time. The exterior finish maintains its appearance while withstanding years of smoke, moisture, and exposure to harsh Chicago weather.

The airtight seal provided by the butterfly closure reduces energy loss by preventing warm indoor air from escaping through the flue. In summer, it blocks humidity and outdoor odors from entering your living space. The improved seal can significantly lower utility costs and enhance indoor comfort throughout the year.
Our technicians measure your chimney’s dimensions to ensure the butterfly cap-damper fits precisely and operates smoothly. The installation includes testing for draft balance, closure integrity, and complete weatherproofing. Routine maintenance checks keep the mechanism clean and responsive, ensuring continued performance through every heating season.
