How strong are skyscraper windows?

Asked by Spargett (5377points) January 26th, 2008

Say I were to run into them with a nice sprint, would I go through? What if two people were to run at the same time. Just curious as to how many pounds of forces those things can withstand.

A MythBusters episode actually covered this.

And the answer was yes, they’re not strong enough to resist you running through them, and at least one person has done so and fallen to his death. Though some posters on that page start to quibble a bit about it. It would depend on the window and what exactly happened.

Also the point of impact is important. A window resist impact more in the center and breaks easier if hit in the corner. The reason for this is the glass actually flexes when hit in the center and the framework makes the glass resist flexing in the corners. As a firefighter we are taught to strike glass in the corner for this reason. We also discharge a CO2 extinguisher at the impact piont before striking it because the cold makes the glass less flexable and causes it to break easier.
