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.
Windstorm: Windstorm, a wind that is strong enough to cause at least light damage to trees and buildings and may or may not be accompanied by precipitation. Wind speeds during a windstorm typically exceed 55 km (34 miles) per hour. Wind damage can be attributed to gusts (short bursts of high-speed winds) or longer periods of stronger sustained winds. Although tornadoes and tropical cyclones also produce wind damage, they are usually classified separately.
