Certain Pella® windows can stop flying 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 thoroughly tested for impact resistance.
Tests consist of firing a two-by-four at the window to make sure 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 engineer a hurricane window with impact-resistant glass, surely we could discover a solution that could halt home runs from Major League Baseball teams.
When Pella was contacted to help equip a historic building by Wrigley Field with home run-resistant windows, that’s precisely what we did.
We overhauled our hurricane cannon to evaluate the home run-resistant windows. We launched baseballs from the cannon at an angle and speed that would reconstruct the force of a home run.
Our tempered glass weathered the hits best because it’s more durable and safer than standard annealed glass.
All About Physics
It takes a speed surpassing 100 mph and a height greater than 100 feet to shoot a baseball out of the park.
In Wrigley’s situation, we found the baseballs would be traveling 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 concerned about an MLB home run being launched at your home, there are a variety of reasons to select durable, tempered glass in your Pella windows and doors.
It’s great for homeowners who want an extra level of security from their windows or patio doors. Or those who are bringing up the next great baseball player.
Look at the benefits and highlights of Pella tempered glass options:
- Toughened glass like what is used in car windows.
- Used where damages from broken glass are a concern.
- Generally breaks 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 learn more about impact windows and if they may be right for your home, call Pella of Raleigh at 919-324-0196. Or, request a free, in-home consultation online.
