Alpine Ventilation’s 150mm mushroom roof cowl provides a robust, weather‑deflecting cap for larger‑capacity vertical duct terminations. The dome shape helps minimise water ingress while supporting free airflow from rangehoods, bathrooms and inline fans. Designed to suit 150mm ductwork, it installs with standard clamps and sealants for a secure, weather‑resistant fit. A reliable finish for roof penetrations in residential and light commercial installations.
