Ridge Ventilator

A ridge vent is a type of vent installed at the peak of a sloped roof which allows warm, humid air to escape a building's attic.This air slot is then covered by the ridge vent itself. They help to provide continuous, uniform exhaust ventilation at the highest portion of the attic and are designed to help resist wind-driven rain and snow, as well as insect and debris infiltration.Ridge ventilators from 610 mm to 1525 mm throat are to be manufactured from solid galvanised steel plate diaphragms with angled base frames fitted at nominal. 2400 mm centres. From 1830 mm to 3660 mm all structural sections will be in steel angle, all hot dip galvanised after fabrication.A ridge vent is usually made from aluminum or a mesh-type material and is installed underneath the final layer of shingles to create airflow across the exterior roof. It draws hot, moist attic air out through the ridge vent and pulls fresh air into the attic through the soffit vents.
