Wind Storms


Extreme Weather

Storms such as hurricanes, cyclones and tornados can each generate windblasts that reach speeds of over 100 mph causing severe structural damage to buildings and can be lethal to humans. In 2005, Hurricane Katrina caused more than $81 billion in damages and took 1,500 lives. It is because of these staggering costs in lives and property that people located in high risk areas need to consider adequately protecting their glazing systems. Even with all the latest weather technology, no one knows when a natural disaster will happen or where it will strike next. Installing protective safety and security films is a cost-efficient way to increase survivability in the event of a serious storm. Safety and security film acts as a protective net, adhering broken glass shards to itself helping to reduce potentially hazardous damage.

Wind pressure from hurricanes is not always constant but in many cases, windows that have applied safety film can stand up to varying high wind-loads. A typical glazing system will face both a "pushing" and "pulling" pressurization, which causes tremendous strain on the framing system often leading to failure. Once an opening is created, the wind pressure inside the structure can cause walls and roofs to collapse. During a violent storm, the most destructive force comes from wind-borne debris such as roofs, trees, doors, etc. These items become in effect, missiles that cause the largest percentage of injuries to humans in addition to costly property damage.

Johnson Window Films Trident is an effective barrier against windstorm damage when professionally installed in conjunction with an anchoring retention system. These films offer increased protection without distorting the view. The selection of film often depends on the proximity of the windstorm and the force of windstorms you might face. There are many factors involved in choosing the proper film and retention system. Consult a Johnson Window Films dealer to have a custom analysis done for your needs.
