Louvre windows typically feature blades made of glass, aluminum, timber, or PVC, with common blade widths ranging from 100mm to 150mm. These blades are set within frames made from durable materials like aluminum or timber and can be operated manually or automatically. Designed for tight sealing, louvre windows offer good energy efficiency when closed. Blades are usually angled between 30° and 45° to optimize airflow while keeping out rain. Available in various configurations, louvre windows can be customized with different glass types such as clear, tinted, or frosted for enhanced privacy, light control, and thermal performance.
