Chimney Caps for Wind Problems

Here the solution to chimney backdraft! These chimney caps are constructed of two concentric hoods that are positioned so the adjacent bands overlap, and so the unit presents a spherical image to the wind, regardless of the wind direction.

When the wind blows, the air is forced around the unit and actually causes an increase in upward draft. The harder the wind blows, the more this effect will increase.

The Vacu Stack wind caps, for example, come with a lifetime warranty and are available in 13 different diameters to fit flue diameters from 3 inches to 16 inches. Two rectangular versions if the Vacu Stack and a custom model can also be ordered. A Vacu Stack chimney cap for air insulated chimneys is another viable chimney backdraft solution for homeowners with this common chimney problem.
