Louvred is an adjective that describes an architectural feature or an object that incorporates louvers. Louvers are slanted or angled horizontal slats set in a frame, typically made of wood, metal, or glass, that are used to allow for the passage of air or light while simultaneously providing protection against direct sunlight, rain, or other elements.
The term "louvred" often refers to windows, doors, or ventilation systems that are constructed with these slatted panels. Louvred windows or doors are designed to provide a controlled flow of air and natural light into a building, while also offering privacy and protection from adverse weather conditions. These slats can be adjustable, allowing the user to regulate the amount of air or light that enters the space.
Additionally, louvred structures or equipment can also include fixed or movable panels that are arranged in parallel rows. Louvred panels may be found in air conditioning units, exhaust systems, or machinery enclosures, serving to prevent the intrusion of foreign objects or particles while still permitting the flow of air or gas.
Overall, the term "louvred" pertains to anything featuring or incorporating louvers, whether in windows, doors, ventilation systems, or other objects requiring the control or passage of air or light.
The word "louvred" comes from the Old English word "lof" or "low", which referred to an opening or aperture. Over time, it evolved into the Middle English word "louvre", which specifically denoted an opening in a wall or roof to allow ventilation. The spelling eventually changed to "louver" in American English, and "louvred" (with -ed) remains the commonly used form in British English.
