Impact Windows Engineered to Withstand Hurricanes and Home Runs

Impact Windows Engineered to Withstand Hurricanes and Home Runs

Certain Pella® windows can halt fast-moving baseballs and others can withstand hurricane-force winds. How?

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

Tests involve blasting a two-by-four at the window to ensure glass remains intact. We use our hurricane cannon to launch the wood, which travels 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 find a fix that could protect from home runs from Major League Baseball teams.

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

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

Our tempered glass resisted the baseballs best because it’s more durable and safer than generally used annealed glass.

All About Physics

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

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

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

More Benefits of Tempered Glass in Pella® Windows

Even if you’re not concerned about an MLB home run hurling at your residence, there are many reasons to use strong, 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 bringing up the next great baseball player.

Consider the advantages and highlights of Pella tempered glass options:

  • Strong glass like what is used in car windows.
  • Used where damages from broken glass are a concern.
  • Usually shatters into small, square parts rather than 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 Danville at 217-443-3355. Or, schedule a free, in-home consultation online.
