What role do external baffles play in ridge vents?
Last Updated 11 years ago

External baffles play a vital role in the effectiveness of a ridge vent.  You want to be sure you have a ridge vent with an external baffle.  Here’s why- as wind hits the external baffle, the wind is forced over the ridge vent creating a low air pressure above the vent’s opening.  This low pressure creates a vacuum effect and pulls air from the attic through the exhaust vent.  

All of Lomanco ridge vents are designed with an external baffle.
