A building “envelope” consists of windows, doors, walls and a roof. When a building envelope begins to break down due to high winds, damage to the building increases dramatically. This process begins when a component or connection fails, and the air pressure within the building increases. When combined with other forces, this internal pressure can lift the roof from the building. Rain and wind can then enter the building and continued strong winds can cause the frame of the building to fail.

The “envelope” of a building consists of the walls, roof, doors and windows. Damage from high winds increases rapidly as the envelope of a building begins to break down. From the first failure, whether it’s a roof panel, a broken window or a door, the internal pressure within the building increases. This force, in combination with other forces can cause the roof to lift from the building. Wind and rain can then enter the building and, if the winds are strong enough, cause structural failure of the frame of the building.
