Chimfex is the indispensable fire suppressant for controlling fires that occur from creosote build-up in chimneys. It is perfect for homeowners or even a professional firefighter to quickly and safely suppress chimney fires. Chimfex is far superior to using water to extinguish a chimney fire, water causes damage to the flue tiles and the chimney which creates damage. Chimfex reduces heat damage with its safe, easy to use application. Activate ChimFex and place it next to the fire and close the fireplace doors or intake vents. ChimFex quickly replaces the oxygen in your chimney and stifles the fire. It continues to produce fumes for a few minutes to ensure the fire does not re-ignite. Having an additional ChimFex stick on hand just in case is recommended. Keep your family safe with ChimFex next to your wood stove, fireplace or fireplace insert.
