Certain Pella® windows can halt speeding baseballs and others can weather 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 consist of blasting a two-by-four at the window to make sure glass stays intact. We use our hurricane cannon to fire the wood, which travels 50 feet per second.
It Started with Hurricane Testing
We figured, if we could design a hurricane window with impact-resistant glass, surely we could come up with a solution that could protect from home runs from Major League Baseball teams.
When Pella was asked to help outfit a historic building by Wrigley Field with home run-resistant windows, that’s precisely what we did.
We modified our hurricane cannon to evaluate the home run-resistant windows. We launched baseballs from the cannon at an angle and speed that would reconstruct the speed of a home run.
Our tempered glass resisted the home runs best because it’s more durable and safer than standard annealed glass.
All About Physics
It warrants a speed of more than 100 mph and a height greater than 100 feet to send a baseball out of the park.
In Wrigley’s scenario, we found the baseballs would be going 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 concerned about an MLB home run propelling toward your home, there are many reasons to choose strong, 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 developing the next great baseball player.
Review the benefits and highlights of Pella tempered glass options:
- Durable glass much 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 Lewes at 302-257-5544. Or, request a free, in-home consultation online.
