Butterfly Cap-Damper - Premium Chimney Cap for Home Protection

Butterfly Cap-Damper | Dual-Function Chimney Protection & Airflow Control
Combine superior draft control and weather protection with a Butterfly Cap-Damper, installed by Chicagoland Fireplace & Chimney Restoration. Stainless steel construction built for long-term efficiency and reliability.

Integrated Design for Protection and Performance

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.

Dual-Action System for Complete Coverage

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.

Crafted from 304 Stainless Steel for Durability

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.

Energy Savings and Comfort Improvements

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.

Professional Installation and Seasonal Maintenance

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.

Annual chimney cleaning helps reduce creosote buildup, improve draft, and spot blockages before winter use. Professional sealing adds a vapor-permeable barrier that repels rain and snow without trapping moisture in masonry.
