Internal Pressurization

Hurricane Shutters can deliver “full envelope” protection of your home or commercial property against hurricane-force winds, preventing internal pressurization of the building. Internal Pressurization happens when strong gusts of wind push into the building, and force upward, creating pressure while wind from the exterior of the building compromises the truss system. The resulting set of forces lifts the roof off because of this massive buildup in pressure. This Internal Pressurization is what causes the often seen roof lift-off and associated catastrophic damage.

Rapid Intensification

Rapid Intensification, also known as RI, is defined by the National Hurricane Center as an “increase in the maximum sustained winds of a tropical cyclone of at least 34.5 MPH in a 24-hour period.” Rapid Intensification can occur regardless of the storm strength or size and is becoming increasingly more common.

Rapid intensification is a serious challenge for the prediction of hurricane intensity. An example is Hurricane Laura that went from a tropical storm with sustained winds of 65 mph early August 25, 2020 to a Category 3 with 115-mph winds the next morning, August 26, 2020. Laura increased into a major Category 4 hurricane before landfall early Thursday, August 27, 2020.
