No, windows and doors do not cause condensation. Exterior condensation is dew; the same condensation you see on car windows, lawns. and streets on many mornings. Dew on windows is a natural atmospheric phenomenon, and it doesnât mean your windows are leaking air.
Simply put, wind driven rain is damage caused by rain that was propelled by wind through the window seals or door seals. In other words, if the wind was not in the equation, the water would never have made it into the dwelling to cause damage.
As the wate vapor in warm air rises through updraft, it condenses and fall as rains but if the updraft is strong rain drops coalesce into hail. Even when the updraft is present, falling rain pulls the surrounding air with it making a downdraft. Normally downdraft is characterised by strong winds with rain and hail.
