Twin Decorative Gable Vents

Twin Decorative Gable Vents.

These are window-like, solid louvered frames in the outer walls of houses. The builder installs the ridge wait strip along this opening, covering it, and then installs the last course of the ridge shingles over the valve. The overlap valves have formed channels that allow airflow and prevent insulation from tapping the entire airspace between the roof loungers.
