Impact Windows Engineered to Withstand Hurricanes and Home Runs

Impact Windows Engineered to Withstand Hurricanes and Home Runs

Certain Pella® windows can put a stop to speeding baseballs and others can withstand hurricane-force winds. How?

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

Tests include blasting a two-by-four at the window to ensure glass stays 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 design a hurricane window with impact-resistant glass, surely we could discover a fix that could protect from home runs from Major League Baseball teams.

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

We retrofitted 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 power of a home run.

Our tempered glass withstood the hits best because it’s more durable and safer than commonly used annealed glass.

All About Physics

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

In Wrigley’s case, we determined the baseballs would be moving at about 60 mph upon hitting windows.

But we exceeded requirements and evaluated 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 being launched at your residence, there are a variety of reasons to choose durable, tempered glass in your Pella windows and doors.

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

Look at the strengths and highlights of Pella tempered glass options:

  • Durable glass much like what is used in car windows.
  • Used where damages from broken glass are a concern.
  • Normally fragments into small, square pieces as opposed to sharp shards if broken.
  • Glass doesn’t come 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 Birmingham at 877-680-9617. Or, request a free, in-home consultation online.
