WHAT IT IS

A static louvred exhaust roof vent is a passive, no-moving-parts ventilation fitting installed through the roof cladding on industrial and commercial buildings in Malaysia. Fixed louvres and an insect screen allow hot air to escape by the stack effect (warm air rises), with no energy input required. Manufactured in aluminium or galvanised steel; face sizes range from 250 × 250 mm to 400 × 400 mm with an integral deck plate for through-sheet mounting. Positioned near the ridge line for maximum thermal extraction. Frequently used alongside turbine ventilators to provide supplementary exhaust ventilation in factories, workshops, and warehouses.
