Windtight is a term used to describe something that is impervious to the wind. The word itself is made up of two parts - wind and tight - which indicate that the object or structure is tightly sealed against the wind. There are several synonyms for windtight, including airtight, draft-free, weatherproof, sealed, and airproof. All of these terms suggest that the object or structure is tightly sealed against the elements and will not allow air to pass through it. Windtight constructions are particularly important in areas that experience extreme weather conditions such as hurricanes, blizzards, and tornadoes, as they help to protect buildings and other structures from wind damage and infiltration.
