Ventilating Openings
Ventilation openings are intake/exhaust vents to circulate air inside and outside rooms, and roughly classified into louvers and registers. Louvers are mainly used for natural ventilation, and shaped in a way that it is hard to see inside the room by placing long and narrow blades at regular intervals. Some types use perforated panels or wire meshes instead of blades. Louvers with wall caps prevent the infiltration of strong rain and wind, and the cap shapes are selectable from the round type, the U type, the square type, the flat type, etc. Registers use filters for ventilation and prevent the intrusion of pollen, yellow sand and insects from outside. Materials of ventilation openings are aluminum, stainless steel, steel, plastic, etc. Select one for the usage environment.
