\n\nDamper plate closes against fiberglass gasket (white) for a tight seal (screen removed for demo).\n\nYou could be losing $350.00 or more out of your chimney, every year, without even knowing it.\n\nHuge heat loss occurs when a chimney�s damper doesn�t seal properly or is missing or broken. You can�t see it, the heat just goes out of the house. If your chimney�s damper isn�t sealing properly it�s like leaving a front door open in the middle of winter.
