Impact Windows Engineered to Withstand Hurricanes and Home Runs

Impact Windows Engineered to Withstand Hurricanes and Home Runs

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

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

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

It Started with Hurricane Testing

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

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

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

Our tempered glass resisted the hits best because it’s stronger and safer than commonly used annealed glass.

All About Physics

It warrants a speed faster than 100 mph and a height exceeding 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 striking 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 thinking about an MLB home run propelling toward your home, there are a variety of reasons to use strong, tempered glass in your Pella windows and doors.

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

Consider the advantages and highlights of Pella tempered glass options:

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

Tempered glass is available in all Pella windows and patio doors. To discover more about impact windows and if they may be right for your home, call Pella of Annapolis at 240-293-1068. Or, book a free, in-home consultation online.
