Feature: 1. WARM IN WINTER AND COOL IN SUMMER: Magnetic fireplace draft stopper can eliminate winter weather airflow, blocking unwanted cold air at home and preventing heat loss. In summer, this fireplace ventilation cover can be used to keep hot and humid air out. 2. IMPROVE ENERGY EFFICIENCY: This fireplace wind screen ensures that your chimney does not become an unwanted source of cold or hot air. This windshield cover improves energy efficiency, allowing you to save on monthly water and electricity. 3. BLOCKING AIR CIRCULATION: Even without a fire, your chimney will continue to generate airflow, which may cause warm air to be sucked out of your home and replaced by cold air outside. Our fireplace barrier is the perfect solution to this common problem. 4. SUITABLE FOR HOME CHIMNEYS: This fireplace cover is the perfect windproof hood that can reduce unwanted pollen and dust entering your home through the fireplace. Our winter and summer fireplace covers are perfect for burning wood or gas fireplaces, making them the perfect companion for your home chimney. 5. EASY TO USE: Our fireplace draft stopper is securely attached to the magnetic vent of the fireplace using a magnet. Simply remove the mapper plug before using the fireplace and reapply it after the fireplace cools down. In addition, our wind plugs can be easily trimmed with a pair of scissors to better fit the ventilation openings of your specific fireplace.
