Certain Pella® windows can halt fast-moving 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 involve blasting a two-by-four at the window to verify glass keeps intact. We use our hurricane cannon to launch 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 solution that could protect from home runs from Major League Baseball teams.
When Pella was approached to help equip a historic building by Wrigley Field with home run-resistant windows, that’s precisely what we did.
We modified our hurricane cannon to experiment on the home run-resistant windows. We launched baseballs from the cannon at an angle and speed that would mimic the power of a home run.
Our tempered glass weathered the hits best because it’s tougher and safer than commonly used annealed glass.
All About Physics
It requires a speed surpassing 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 traveling at about 60 mph upon hitting windows.
But we did more than what was expected and tested 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 hurling at your home, there are many reasons to use strong, tempered glass in your Pella windows and doors.
It’s great for homeowners who want an added 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:
- Durable glass similar to what is used in car windows.
- Used where cuts from broken glass are a concern.
- Generally breaks into small, square pieces 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 Fargo at 701-281-1390. Or, book a free, in-home consultation online.
