Compatible with both Concrete Tile and Metal roofs, the G750N is suitable for new construction projects, re-roofing applications, as well as retrofitting.
Its application depends on the pitch and design of the roof construction. The G750N features evenly spaced openings that prevent large insects from gaining access and will achieve BAL compliance up to BAL19 without the application of BAL mesh while allowing airflow to prevent capillary action.
This vent can be used independently or in conjunction with other VENT Systems products to create a comprehensive passive ventilation system.
