Sunshade louvres, also known as sun control devices or sun screens, are designed to reduce the amount of direct sunlight that enters a building, while still allowing natural light in. These louvres consist of a series of horizontal slats that can be fixed or adjustable to any angle on the facade of a building or installed above windows or doors.
In addition to controlling the amount of sunlight entering a building, sunshade louvres can also reduce excessive heat gain, resulting in lower air conditioning requirements and energy savings3. Conversely, in colder months, sunshade louvres can allow more solar heat gain into the interior of a building, reducing the cost of heating.
Sunshade louvres come in various sizes and shapes, and can be made of different materials such as wood, metal, or fabric. They can be designed to block direct sunlight during the hottest parts of the day, and to allow greater light penetration during cooler times. Sunshade louvres can also protect windows from damage caused by windblown debris during storms.
