6 Inch Vacu Stack Chimney Cap Air insulated Chimney Pipe

Prevents wind induced downdraft regardless of wind direction (even downward.) Accelerated air flow around the Vacu-Stack creates a venturi, causing flue gasses to flow up and out of the chimney. Note: For Air-Cooled Double and Triple Walled Chimneys. These models feature separate passages for cooling air to flow uninterrupted through convection cooled chimneys.
