Louvers are architectural features used primarily for ventilation, light control, and aesthetic purposes. They consist of angled slats or blades, which can be fixed or adjustable, allowing air and light to pass through while providing protection from rain, direct sunlight, and noise. In ventilation, louvers facilitate airflow in and out of buildings, helping to regulate temperature and improve air quality by allowing fresh air to enter and stale air to exit. This is particularly useful in industrial settings, HVAC systems, and residential buildings where maintaining a comfortable indoor environment is crucial. For light control, louvers help manage the amount of natural light entering a space, reducing glare and heat gain. This can enhance energy efficiency by minimizing the need for artificial lighting and air conditioning, especially in hot climates. Louvers can be oriented to block direct sunlight while still allowing diffused light, creating a pleasant indoor ambiance. Aesthetically, louvers add a modern and sleek appearance to buildings. They can be customized in various materials, colors, and designs to complement architectural styles. Louvers are often used in facades, windows, and doors, contributing to a building's visual appeal while serving functional purposes. In addition to these primary uses, louvers can also provide privacy and security. By obstructing direct views into a building, they offer privacy without completely blocking light and air. In some cases, louvers are integrated into security systems, acting as barriers that are difficult to penetrate. Overall, louvers are versatile components that enhance building performance, comfort, and aesthetics, making them a valuable addition to both residential and commercial architecture.

Louvers prevent rain from entering by utilizing their angled slat design, which allows air to pass through while blocking direct rain entry. The slats are typically set at a downward angle, which deflects rainwater away from the opening. This angle ensures that rainwater hits the slats and is directed downwards, away from the interior space. The spacing and overlap of the slats are crucial. They are designed to be close enough to prevent rain from passing through while still allowing adequate airflow. The overlap between slats creates a barrier that rain cannot easily penetrate, as the water would have to travel upward against gravity to enter. Additionally, louvers often incorporate drainage channels or weep holes at the bottom to collect and channel any water that does manage to get past the initial slats. This water is then directed away from the building, preventing accumulation and potential leakage. The material and surface finish of the louvers can also play a role in rain prevention. Smooth, water-repellent surfaces encourage rainwater to slide off quickly, reducing the chance of water ingress. In some designs, louvers are equipped with additional features like rain hoods or baffles, which provide an extra layer of protection by extending the path rainwater must take to enter, further reducing the likelihood of water penetration. Overall, the combination of angled slats, strategic spacing, drainage systems, and additional protective features work together to effectively prevent rain from entering through louvers while maintaining ventilation.
