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 rigorously 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 propel the wood, which moves 50 feet per second.
It Started with Hurricane Testing
We thought, if we could design a hurricane window with impact-resistant glass, surely we could come up with a resolution that could stop home runs from Major League Baseball teams.
When Pella was approached 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 fired baseballs from the cannon at an angle and speed that would reconstruct the power of a home run.
Our tempered glass withstood the baseballs best because it’s tougher and safer than generally used annealed glass.
All About Physics
It takes a speed surpassing 100 mph and a height greater 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 impact with windows.
But we exceeded requirements 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 home, there are many reasons to choose 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 bringing up the next great baseball player.
Look at the advantages and highlights of Pella tempered glass options:
- Strong glass similar to what is used in car windows.
- Used where injuries from broken glass are a concern.
- Generally breaks into small, square parts instead of sharp shards if broken.
- Glass doesn’t break 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 Muncie at 317-983-5642. Or, book a free, in-home consultation online.
