Description

Also seen as the alpha slate vent, it's usable for high and low-level roof ventilation requirements. The hood features a 4mm fly screen to prevent blockage from falling debris and prevent large insects from entering the roof space. Manufactured from UV-stabilised polypropylene, this contributes to its long lifespan, plus allows 10,000mm² airflow per vent for reliable roof ventilation.
