Modular Extensions 3/4 Stainless Steel
Expand and customize your stainless steel chimney cap system with CA 5/8 Modular Extensions from Chicagoland Fireplace & Chimney Restoration. Built for precision fit, stability, and long-term performance.

Controlling airflow is essential to keeping your fireplace safe and efficient. The Butterfly Damper provides smooth, even regulation of exhaust gases while reducing heat loss and preventing backdrafts. Unlike traditional throat dampers, this model features dual rotating plates that open and close with balanced precision—ensuring better sealing when closed and controlled ventilation when open. At Chicagoland Fireplace & Chimney Restoration, we install butterfly dampers crafted from durable stainless steel for long-lasting, maintenance-free performance.

The twin-blade mechanism allows precise adjustment of the flue opening, maintaining proper draft for wood-burning and gas fireplaces alike. Its circular motion ensures uniform airflow, eliminating uneven burning and smoke rollbacks. This design minimizes pressure differences, keeping indoor air quality clean and combustion efficient through every use.
Each damper is fabricated from 304 stainless steel, chosen for its ability to resist heat, moisture, and corrosion. The blades pivot smoothly on reinforced pins, supported by precision bearings that won’t warp or seize over time. This construction guarantees quiet operation and a secure seal, even after years of repeated use.

When not in use, the butterfly damper seals tightly to prevent warm air from escaping up the flue. This energy-saving feature helps maintain stable indoor temperatures and reduces heating costs during winter months. In warmer seasons, the damper can remain partially open to provide gentle ventilation without compromising energy efficiency.

Our technicians ensure proper sizing, placement, and calibration for every installation. Each unit is positioned to optimize airflow, reduce turbulence, and match your fireplace’s flue geometry. Once installed, the damper is tested for smooth operation, full closure, and balanced airflow under draft pressure.
