Interior louvers are window or door shutters with horizontal slats that let in light and air but keep out rain and direct sunshine. Interior louvers also help dampen noise, and the slats are adjustable to let in different amounts of sunlight throughout the day.
Louvers typically are made of aluminum, wood, glass or metal, and owners can control them with the use of a pulley or metal lever. Some modern louvers have motorized controls for opening. When hanging louvers, companies can install them as one piece for a modern look and maximum visibility or as two pieces for a more traditional look. Manufacturers offer interior louvers in many different material options, and users can select specific designs such as sunburst radials or cafe doors to match their decor.
