Certain Pella® windows can halt speeding baseballs and others can weather hurricane-force winds. How?
When it comes to hurricane-resistance, Pella HurricaneShield® windows and patio doors rated to ASTM E1996 missile D rating are meticulously 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 travels 50 feet per second.
It Started with Hurricane Testing
We figured, if we could engineer a hurricane window with impact-resistant glass, surely we could discover a fix that could stop home runs from Major League Baseball teams.
When Pella was contacted to help supply a historic building by Wrigley Field with home run-resistant windows, that’s just what we did.
We modified our hurricane cannon to evaluate the home run-resistant windows. We fired baseballs from the cannon at an angle and speed that would reconstruct the power of a home run.
Our tempered glass weathered the baseballs best because it’s tougher and safer than commonly used annealed glass.
All About Physics
It warrants a speed faster than 100 mph and a height of more than 100 feet to shoot a baseball out of the park.
In Wrigley’s case, we determined the baseballs would be traveling at about 60 mph upon striking windows.
But we did more than what was expected and checked impact resistance up to 100 mph.
More Benefits of Tempered Glass in Pella® Windows
Even if you’re not worried about an MLB home run hurling at 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 safety from their windows or patio doors. Or those who are developing the next great baseball player.
Review the advantages and highlights of Pella tempered glass options:
- Durable glass like what is used in car windows.
- Used where cuts from broken glass are a concern.
- Generally breaks 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 discover more about impact windows and if they may be right for your home, call Pella of Woburn at 781-935-4947. Or, book a free, in-home consultation online.
