Certain Pella® windows can stop flying baseballs and others can weather hurricane-force winds. How?
In regard to hurricane-resistance, Pella HurricaneShield® windows and patio doors rated to ASTM E1996 missile D rating are meticulously tested for impact resistance.
Tests involve blasting a two-by-four at the window to verify glass remains intact. We use our hurricane cannon to fire the wood, which travels 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 come up with a fix that could halt home runs from Major League Baseball teams.
When Pella was approached to help outfit a historic building by Wrigley Field with home run-resistant windows, that’s exactly what we did.
We modified our hurricane cannon to test the home run-resistant windows. We launched baseballs from the cannon at an angle and speed that would mimic the speed of a home run.
Our tempered glass resisted the hits 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 exceeding 100 feet to send a baseball out of the park.
In Wrigley’s scenario, we found the baseballs would be traveling at about 60 mph upon striking windows.
But we went above and beyond 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 a lot of reasons to use tough, tempered glass in your Pella windows and doors.
It’s great for homeowners who want an additional level of security from their windows or patio doors. Or those who are raising the next great baseball player.
Look at the benefits and highlights of Pella tempered glass options:
- Toughened glass similar to what is used in car windows.
- Used where damages from broken glass are a concern.
- Usually shatters into small, square pieces as opposed to sharp shards if broken.
- Glass doesn’t break 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 Fall River at 508-939-3464. Or, request a free, in-home consultation online.
