Certain Pella® windows can stop fast-moving 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 include blasting a two-by-four at the window to ensure glass stays intact. We use our hurricane cannon to propel the wood, which moves 50 feet per second.
It Started with Hurricane Testing
We thought, if we could create a hurricane window with impact-resistant glass, surely we could find a solution that could stop home runs from Major League Baseball teams.
When Pella was asked to help equip a historic building outside of Wrigley Field with home run-resistant windows, that’s just 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 recreate the force of a home run.
Our tempered glass weathered the home runs best because it’s stronger and safer than generally used annealed glass.
All About Physics
It takes a speed faster than 100 mph and a height of more than 100 feet to launch a baseball out of the park.
In Wrigley’s case, we determined the baseballs would be going at about 60 mph upon hitting windows.
But we went above and beyond 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 hurling at your residence, there are a lot of reasons to choose strong, tempered glass in your Pella windows and doors.
It’s good 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.
Review the benefits and highlights of Pella tempered glass options:
- Strong glass like what is used in car windows.
- Used where cuts from broken glass are a concern.
- Normally fragments into small, square pieces as opposed to sharp shards if broken.
- Glass doesn’t come apart if shattered.
Tempered glass is available in all Pella windows and patio doors. To discover more about impact windows and if they may be right for your home, call Pella of Southern Pines at 910-444-0729. Or, request a free, in-home consultation online.
