Certain Pella® windows can stop flying 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 thoroughly tested for impact resistance.
Tests involve shooting a two-by-four at the window to ensure glass stays intact. We use our hurricane cannon to fire the wood, which covers 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 protect from home runs from Major League Baseball teams.
When Pella was asked to help supply a historic building outside of 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 shot baseballs from the cannon at an angle and speed that would mimic the force 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 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 moving at about 60 mph upon impact with windows.
But we exceeded requirements and checked 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 hurling at your windows, there are a lot of reasons to use durable, tempered glass in your Pella windows and doors.
It’s ideal for homeowners who want an added level of protection from their windows or patio doors. Or those who are developing the next great baseball player.
Consider the advantages and highlights of Pella tempered glass options:
- Toughened glass much like what is used in car windows.
- Used where cuts from broken glass are a concern.
- Usually shatters into small, square pieces rather than sharp shards if broken.
- Glass doesn’t come 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 Natick at 781-239-1161. Or, schedule a free, in-home consultation online.
