Aluminium louver vents are a type of ventilation system used to control the flow of air in a building. They are made up of a series of angled slats that are connected together to form a single unit. The slats are usually made of aluminium, although other materials such as plastic and wood can also be used. The louvers are typically installed in the walls or ceiling of a building to allow air to enter and exit the space. The angle of the slats can be adjusted to control the amount of air that enters or exits the space. This type of ventilation system is ideal for controlling the temperature of a room, as well as providing ventilation for the building. Louver vents are also often used in conjunction with other ventilation systems, such as fans and air conditioning units, to ensure that the air quality in the building is kept at an optimal level.
