Top sealing chimney caps create a tight seal at the top of your chimney to prevent heat loss and energy dollars from being wasted up and out the chimney. Top sealing chimney caps are designed to stop cold air from coming down the flue, and expensive conditioned air from going up the chimney. Top sealing chimney caps are made of cast aluminum and are available in a variety of sizes.
