Louvre windows feature horizontal slats that allow light and air to pass while still providing privacy and protection from the rain. The horizontal slats (louvres) are adjustable and can be easily angled to allow more or less breeze through depending on your needs, making them very easy to operate and providing a high degree of control over natural light and airflow. This popular window variety is best suited to smaller windows and is also a good choice for bathrooms, toilets and laundries as an alternative to exhaust fans.
