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 resist hurricane-force winds. How?

When it comes to hurricane-resistance, Pella HurricaneShield® windows and patio doors rated to ASTM E1996 missile D rating are thoroughly tested for impact resistance.

Tests include shooting a two-by-four at the window to make sure glass remains intact. We use our hurricane cannon to fire the wood, which moves 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 find a fix that could protect from home runs from Major League Baseball teams.

When Pella was contacted to help equip a historic building near Wrigley Field with home run-resistant windows, that’s just 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 mimic the power 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 requires a speed faster than 100 mph and a height of more than 100 feet to shoot a baseball out of the park.

In Wrigley’s case, we found the baseballs would be going at about 60 mph upon impact with windows.

But we went above and beyond and evaluated 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 propelling toward your windows, there are a lot of reasons to use durable, tempered glass in your Pella windows and doors.

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

Consider the strengths and highlights of Pella tempered glass options:

  • Strong glass like what is used in car windows.
  • Used where cuts from broken glass are a concern.
  • Usually shatters into small, square pieces 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 find out more about impact windows and if they may be right for your home, call Pella of Wilmington at 910-218-9596. Or, schedule a free, in-home consultation online.
