Features 1. WARM IN WINTER AND COOL IN SUMMER: The magnetic fireplace draft stopper helps eliminate airflow from the chimney, blocking cold air from entering your home during winter and preventing heat loss. In summer, it helps keep hot and humid outdoor air from coming inside. 2. IMPROVE ENERGY EFFICIENCY: This fireplace draft cover helps prevent your chimney from becoming an unwanted source of drafts. It improves energy efficiency by reducing air exchange, helping maintain indoor temperatures. 3. REDUCES AIR INFILTRATION: Even when not in use, chimneys can allow continuous airflow, drawing warm indoor air out and letting cold air in. This draft stopper provides an effective solution to minimize unwanted air movement. 4. SUITABLE FOR RESIDENTIAL CHIMNEYS: This cover helps reduce the entry of dust, pollen, and debris through the fireplace opening. It is designed for use with both wood-burning and gas fireplaces, making it ideal for home use. 5. EASY TO INSTALL AND USE: The draft stopper attaches securely to the fireplace vent with built-in magnets. Simply remove it before using the fireplace and reinstall it once the chimney has cooled. It can be easily trimmed with scissors to fit the specific dimensions of your fireplace opening.
