Vacu-Stack

Vacu-Stack® - Part# VSS
This is the premier chimney cap for solving common, wind-related draft problems. These problems often occur for homes that have hills, mountains, tall trees or buildings in the vicinity.
How it works: When wind flows around the Vacu-Stack's unique design, wind speeds increase which creates a partial vacuum. This vacuum then pulls flue gases up and out of the chimney, thus preventing wind-induced downdraft and the resulting infiltration of smoke, odor, and flue gas into your home.
This cap also functions as a conventional chimney cap by protecting the chimney from rain, snow, debris, and animals. It is designed for round chimneys that are not air insulated (also called air-cooled). The Vacu-Stack can also be installed on a square or rectangular chimney using the Masonry Adaptor.

This model work with the following types of chimneys:
  • Single wall
  • Masonry
  • Solid pack insulated
  • Class A
  • B vent
  • All the Vacu-Stack® chimney caps are made of durable 304 Stainless Steel.
    Please be aware that any Vacu-Stack chimney cap that is larger than 12" will be custom made and will ship out in 1-2 weeks.
