louvered

Louvered refers to surfaces constructed with a set of angled slats, or louvers, designed to control light, air flow, and privacy while providing some weather protection. Louvers can be fixed in place or operable, allowing users to adjust the amount of ventilation or shading. The term is used across architecture, interior design, and manufacturing.

Common applications include exterior shutters or façade screens with adjustable slats, louvered windows and doors, and vent covers for heating, ventilation, and air conditioning systems. Interior uses include cabinet doors, room dividers, and acoustic screens that combine light control with visibility.

Louvers are typically made from wood, aluminum, steel, or durable plastics. They are installed in frames with precise angles and spacing to balance airflow, weather resistance, and maintenance needs. Fixed louvers provide constant shading and ventilation, while operable louvers enable adaptive control.

Design considerations cover climate, energy efficiency, moisture exposure, and wind loads. Louvered surfaces influence glare, privacy, acoustics, and appearance, and may be horizontal or vertical. They can be combined with glass, perforated metal, or solid panels to meet functional and aesthetic goals.
