Impact Windows Engineered to Withstand Hurricanes and Home Runs

Impact Windows Engineered to Withstand Hurricanes and Home Runs

Certain Pella® windows can stop flying baseballs and others can resist hurricane-force winds. How?

In regard to hurricane-resistance, Pella HurricaneShield® windows and patio doors rated to ASTM E1996 missile D rating are meticulously tested for impact resistance.

Tests consist of firing a two-by-four at the window to make sure glass remains intact. We use our hurricane cannon to propel the wood, which covers 50 feet per second.

It Started with Hurricane Testing

We thought, if we could engineer a hurricane window with impact-resistant glass, surely we could come up with a fix that could stop home runs from Major League Baseball teams.

When Pella was contacted to help supply a historic building outside of Wrigley Field with home run-resistant windows, that’s precisely what we did.

We overhauled our hurricane cannon to experiment on the home run-resistant windows. We launched baseballs from the cannon at an angle and speed that would recreate the speed of a home run.

Our tempered glass weathered the baseballs best because it’s stronger and safer than generally used annealed glass.

All About Physics

It takes a speed faster than 100 mph and a height of more than 100 feet to send a baseball out of the park.

In Wrigley’s situation, we learned the baseballs would be going at about 60 mph upon hitting windows.

But we exceeded requirements and checked impact resistance up to 100 mph.

More Benefits of Tempered Glass in Pella® Windows

Even if you’re not worried about an MLB home run hurling at your home, there are many reasons to select tough, tempered glass in your Pella windows and doors.

It’s good for homeowners who want an extra level of safety from their windows or patio doors. Or those who are bringing up the next great baseball player.

Consider the strengths and highlights of Pella tempered glass options:

  • Toughened glass like what is used in car windows.
  • Used where cuts from broken glass are a concern.
  • Normally fragments into small, square fragments instead of sharp shards if broken.
  • Glass doesn’t fall apart if shattered.

Tempered glass is available in all Pella windows and patio doors. To learn more about impact windows and if they may be right for your home, call Pella of Bloomington at 309-663-7132. Or, schedule a free, in-home consultation online.
