Louvers are architectural and design elements that are used to control the flow of air, light, and sometimes water in various structures. They typically consist of a series of parallel slats or blades that are set at an angle to allow ventilation while blocking direct light and rain.

1. Design and Structure: Louvers are made up of angled slats or blades that are arranged in a way that they can regulate the passage of air and light. The slats are often adjustable, which allows for control over how much air or light passes through.

2. Materials: They can be constructed from a variety of materials including wood, metal, plastic, or glass. The choice of material often depends on the application, durability requirements, and aesthetic preferences.

3. Applications:

   • Ventilation: Louvers are commonly used in buildings for natural ventilation. They help to circulate air, reducing the need for mechanical ventilation systems.
   • Sun Control: They can be used to manage the amount of sunlight entering a space, which can help in reducing glare and heat gain.
   • Privacy: In residential settings, louvers can offer privacy while still allowing for airflow.
   • Architectural Aesthetics: Louvers can also be used as a design element to enhance the visual appeal of a building.

4. Adjustability: Many louvers are adjustable, meaning the angle of the slats can be changed to control the amount of light and airflow. This adjustability can be manual or automated.

5. Types:

   • Fixed Louvers: These have slats that are permanently set at a certain angle and are not adjustable.
   • Adjustable Louvers: These allow for the angle of the slats to be changed according to the needs of the user.
   • Vertical or Horizontal: Louvers can be oriented vertically or horizontally depending on the desired effect and the design of the building.
