Important Installer Notice – Weather Sealing &
Vapor Barriers
It is the installer's responsibility to ensure that vent installations
through exterior walls are caulked and weatherproofed in such
a manner as to:
• Prevent rain water from entering the wall from the weather
side by adequately caulking the outer vent plate to the exterior
wall surface.
• Prevent moisture inside the home from penetrating into the
wall structure by ensuring the inside wall plate is adequately
sealed to the inside vapor barrier.
• Prevent rain water and moisture from entering the walls by
sealing the joints between the outer vent tube and the inner
and outer wall plates.
We recommend the use of a high quality polyurethane sealant.
