The most effective draft inducing Chimney Caps are able to:
#1: Separate the wind stream as it flows over the cap
#2: Rotate to align with the direction of the wind
Our Wind Directional Caps provide maximum drafting by accomplishing both of these items
When installed, the pivoting hood is kept in proper position (relative to the wind) by the vane. Air movement past the hood creates a partial vacuum in the flue enhancing efficiency and helping to prevent downdraft.
The sizes below are designed to fit the outside diameter of your single wall chimney pipe. If installing on square masonry tile or on to double and triple wall pipe see our adapters HERE.
