Tornado-Resistant Windows

The perfect enhancement

Thanks to a new window, developed by Pittsburgh Corning Corporation, the windows in a Monolithic Dome can now be as tornado-safe as the dome has always been.

These tornado-resistant windows meet criteria stipulated by FEMA 361 Design and Construction Guidelines and have passed air pressure and tornado missile impact tests. They can withstand tornadoes of up to 250 mph, and that’s virtually as bad as a tornado gets.

According to Pittsburgh Corning, “The Tornado-Resistant Window provides the needed protection from the elements while letting people see what is happening outside of the shelter. It also allows for day lighting to enter the space which is a benefit both when using the space as a shelter and also as a multipurpose area during other non-critical times.”

That website includes a link to a video of the “Missile Impact Test” that was conducted. They fired a 15-pound 2×4 at 100 mph at the tornado-resistant window. The first shot hit the center of the window and the second hit a corner of the window, but neither damaged the panel behind the window.

Available through Monolithic

Monolithic is offering to install these windows in Monolithic Domes. You can order them clear or slightly frosted. We can see where they would be wonderful, especially in rooms at convalescent buildings.

Watch the “Missile Impact Test” that Pittsburgh Corning Corporation recently produced to demonstrate the capability of their newly developed “Tornado-Resistant Windows.” During that test, a 2×4 weighing 15 pounds and traveling at 100 mph was fired twice at the Tornado-Resistant Window. The window withstood a hit to its center and a hit at an upper corner. These windows are now available through Monolithic.
