A flashing construction for a curtain wall utilizing The Equal Pressure Principle. Said flashing construction comprises a plurality of vertical mullions disposed parallel to each other and panels being mounted between said mullions. An enclosed vertical space is formed between the mullion and the panel; also, intake ports to the open air are provided on the mullion, whereby said vertical space is connected to the open air through said intake ports. As a result, the pressure in said vertical space is equalized to that of the open air.
