The low-profile, shingle-over look of VenturiVent Plus creates a clean, uncluttered roofline. It installs on the peak of the roof, allowing exhaust ventilation along the entire ridge - end-to-end. With a 12" width, matching shingles can be installed over the vent, allowing the vent to appear almost invisible from the ground. VenturiVent Plus features an external baffle that maximizes airflow performance and helps protect the attic from weather infiltration.
