The GAF Master Flow Aluminum Slant Back Roof Louver is designed for attic ventilation. The fully enclosed hood deters rodent and insect infiltration and leaf and pine needle clogging. The aluminum slant back roof louver is an excellent choice against weather infiltration, especially in steep-slope applications. Each vent offers a full 60 sq. in. of net free ventilating area (NFA).
