List of featured suppliers of ROOF VENTILATION Cowl on Building Products Index
Roof ventilation refers to the system of allowing air to flow through the space between the roof and the ceiling. This is important to prevent moisture buildup and to regulate the temperature inside the building. A cowl is a device that is installed on top of a roof vent to help control the airflow and prevent rain or wind from entering. It is usually made from metal or plastic and has an opening that allows air to pass through while also deflecting any precipitation. The cowl must be appropriately sized and positioned to ensure proper ventilation and prevent any blockages or obstructions.
