Indoor air is kept fresh and healthy with proper ventilation. A louvre is a ventilation product that allows air to pass through it whilst keeping out unwanted elements such as water, dirt and debris. BS EN 13181 is a European Standard that discusses terminals for building ventilation. BS EN 13181 specifies a method for measuring the sand rejection efficiency of sand
