VenTubes

Ventubes are hollow stainless steel cylinders installed in chimneys that provide cross ventilation for large flues. When properly installed, they prevent moisture damage that results from condensation in the large cavities surrounding the flue liners. They do this by allowing up to 85% of the condensation inside of the cavity to escape.

  • Provides Cross Ventilation for Large Flues
  • Prevents Moisture Damage
  • Helps Prevent Efflorescence and Spalling
  • Easy to Install
  • Wire Screen Guard to Prevent Insects
  • Angled Tip Keeps Water Out
  • 100% Stainless Steel

Description

Ventubes are hollow cylinders constructed of 100%, 304 series stainless steel. Each tube is 1/2″ in diameter and 4 1/2″ in length. A wire screen is welded in the front of each tube to prevent insect intrusion. VenTubes provide cross ventilation in chimneys with large cavity areas surrounding the flue liner. The tubes help prevent water damage caused by condensation common to this type of chimney construction.

Ventubes prevent moisture damage that results from condensation in the large cavities, or chase areas, surrounding flue liners. Moisture vapor held in large cavity areas often condenses on the inside of outer chimney walls when wall surface temperatures fall below air temperatures.

VenTubes help to prevent the efflorescence, spalling, and freeze/thaw damage that is caused by condensation in these cavity areas. VenTubes can eliminate up to 85% of the moisture that damages chimneys with large chase areas. Easy to install, they solve an often overlooked moisture problem.

Years of field observation indicated that chimneys with large cavities surrounding the liners deteriorate much faster than chimneys built according to the recommendations of the Brick Institute of America (BIA), which recommends one inch of air space between the liner and outer brick.

Note: Do not install VenTubes in chimneys which have damaged, cracked, or misaligned flue liners. Do not install Ventubes below the roof line or other combustible exposures.

ChimneySaver Water-Base Water Repellent

ChimneySaver Water-Base Water Repellent is a penetrating, V.O.C. compliant, water repellent which contains a proprietary modified siloxane. This water-based siloxane penetrates masonry up to 1/4 inch or more depending on surface porosity and moisture content at the time of application. ChimneySaver Water-Base Water Repellent reacts with the minerals in masonry in the presence of ultraviolet light and atmospheric moisture. This reaction forms strong permanent bonds beneath the surface and creates a hydrophobic zone that prevents water molecules from penetrating, while allowing free migration of water vapors. The chemical bonds formed in this process allow ChimneySaver Water-Base Water Repellent to become an integral part of the substrate and provide long term water repellent protection.
  • 10 Year Warranty
  • VOC Compliant in All States
  • 100% Vapor Permeable
  • Non-Glossy Look
  • Efflorescence Protection
  • Freeze/Thaw Protection
  • Can Be Used On Most Vertical, Above-Grade Masonry
