Certain Pella® windows can stop flying baseballs and others can resist 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 firing a two-by-four at the window to make sure 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 come up with a fix that could halt home runs from Major League Baseball teams.
When Pella was asked to help supply a historic building by Wrigley Field with home run-resistant windows, that’s precisely what we did.
We retrofitted our hurricane cannon to evaluate the home run-resistant windows. We shot baseballs from the cannon at an angle and speed that would reconstruct the power of a home run.
Our tempered glass withstood the home runs best because it’s stronger and safer than standard annealed glass.
All About Physics
It warrants a speed of more than 100 mph and a height of more than 100 feet to shoot a baseball out of the park.
In Wrigley’s scenario, we learned the baseballs would be going at about 60 mph upon impact with windows.
But we did more than what was expected 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 propelling toward your home, there are a lot of reasons to use durable, 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.
Consider the benefits and highlights of Pella tempered glass options:
- Toughened glass similar to what is used in car windows.
- Used where injuries from broken glass are a concern.
- Normally fragments into small, square pieces instead of sharp shards if broken.
- Glass doesn’t come 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 Haverhill at 978-373-2500. Or, book a free, in-home consultation online.
