Impact Windows Engineered to Withstand Hurricanes and Home Runs

Impact Windows Engineered to Withstand Hurricanes and Home Runs

Certain Pella® windows can halt speeding baseballs and others can weather hurricane-force winds. How?

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

Tests involve blasting a two-by-four at the window to ensure glass keeps intact. We use our hurricane cannon to fire the wood, which moves 50 feet per second.

It Started with Hurricane Testing

We figured, if we could create a hurricane window with impact-resistant glass, surely we could find a resolution that could halt home runs from Major League Baseball teams.

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

We modified our hurricane cannon to evaluate the home run-resistant windows. We shot baseballs from the cannon at an angle and speed that would mimic the speed of a home run.

Our tempered glass resisted the baseballs best because it’s tougher and safer than standard annealed glass.

All About Physics

It requires a speed of more than 100 mph and a height of more than 100 feet to launch a baseball out of the park.

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

But we went above and beyond and tested impact resistance up to 100 mph.

More Benefits of Tempered Glass in Pella® Windows

Even if you’re not thinking about an MLB home run propelling toward your home, there are many reasons to use tough, tempered glass in your Pella windows and doors.

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

Review the advantages and highlights of Pella tempered glass options:

  • Durable glass similar to what is used in car windows.
  • Used where cuts from broken glass are a concern.
  • Normally fragments into small, square parts as opposed to 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 Greenfield at (413) 829-0299. Or, schedule a free, in-home consultation online.
