Parapet drains are channels installed at the edge of an elevated structure to carry and redirect rainwater away from the building's facade. These channels are typically made of metal or PVC and are affixed to the parapet wall, allowing water to flow down the channel to a downspout or gutter system. Balcony drainage systems are similar but are installed on the balcony or terrace itself to prevent water buildup and damage. These systems typically feature a drainage slope that funnels water into a drain, which is often located at the lowest point in the balcony or terrace.
