seinäventtiilit

Seinäventtiilit, often translated as wall vents or air bricks, are passive ventilation components installed in exterior walls of buildings. Their primary function is to allow the controlled intake or exhaust of air into or out of a building's interior. Typically made of brick, concrete, plastic, or metal, they are designed to permit airflow while preventing the ingress of rain, snow, and larger pests.

These vents are crucial for maintaining indoor air quality and preventing moisture buildup. In older buildings, they often serve as a primary method of natural ventilation, allowing fresh air to circulate and stale, humid air to escape. This helps to mitigate issues such as condensation, mold growth, and the accumulation of pollutants. Seinäventtiilit can be found in various configurations, including simple openings with protective grilles or more complex designs with adjustable dampers to control airflow.

Their installation is generally straightforward, requiring a pre-cut opening in the wall. The size and number of seinäventtiilit needed depend on factors such as building size, intended use, and local climate conditions. While modern buildings often incorporate more sophisticated mechanical ventilation systems, seinäventtiilit continue to play a role, particularly in older structures and as supplementary ventilation elements in newer ones, contributing to a healthier and more comfortable indoor environment.
