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.
Jet stream is a type of wind. An upper wind to be more precise. So, it behaves exactly like the normal wind, which we feel everyday. Wind is the result of horizontal pressure difference. It flows from a region of higher pressure to a region of lower pressure. In theory, wind should flow directly between pressure differentials.
