Anotations

Scope note:

Horizontal slats, blades, or baffles arranged to be sloping and overlapping, fixed or adjustable. In construction, louvers are used to exclude rain or snow, to admit air or light in varying degrees, to shield a light source from view at certain angles, or to absorb unwanted light. Examples include as used in doors, windows, lighting devices, and the intakes and exhausts of mechanical ventilation systems. For shutters having louvers, use "louvered shutters." For blinds having slats or baffles, use "blinds (coverings)."
