PURPOSE: A blade for a louver and a rectifying louver is provided to reduce energy loss by easily controlling the temperature of a structure that uses the louver. CONSTITUTION: A blade(1) for a louver comprises an inclined portion(4), a rainwater cutoff protrusion(20), and a rectifying portion(40). The inclined portion is inclined from an outside intake side to an inside discharge side. The rainwater cutoff protrusion is formed on the top surface of the inclined portion and cuts off rainwater flowing into the discharge side. The rectifying portion is horizontally extended from the inner end of the inclined portion and rectifies air currents. |
