Certain Pella® windows can stop flying baseballs and others can withstand hurricane-force winds. How?
As far as 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 ensure glass keeps intact. We use our hurricane cannon to propel the wood, which travels 50 feet per second.
It Started with Hurricane Testing
We concluded, if we could create a hurricane window with impact-resistant glass, surely we could discover a solution that could stop home runs from Major League Baseball teams.
When Pella was contacted to help supply a historic building outside of Wrigley Field with home run-resistant windows, that’s exactly what we did.
We overhauled our hurricane cannon to test 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 home runs best because it’s stronger and safer than generally used annealed glass.
All About Physics
It warrants a speed of more than 100 mph and a height exceeding 100 feet to launch a baseball out of the park.
In Wrigley’s scenario, we learned the baseballs would be moving at about 60 mph upon striking 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 home, there are many reasons to select durable, tempered glass in your Pella windows and doors.
It’s great for homeowners who want an added level of security from their windows or patio doors. Or those who are bringing up the next great baseball player.
Review the advantages 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 parts instead of sharp shards if broken.
- Glass doesn’t fall 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 Memphis at 901-401-9399. Or, request a free, in-home consultation online.
