Impact Windows Engineered to Withstand Hurricanes and Home Runs
Certain Pella® windows can put a stop to fast-moving 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 rigorously tested for impact resistance.
Tests consist of firing a two-by-four at the window to verify glass remains intact. We use our hurricane cannon to fire the wood, which moves 50 feet per second.
It Started with Hurricane Testing
We thought, if we could engineer a hurricane window with impact-resistant glass, surely we could find a fix that could halt 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 precisely what we did.
We overhauled our hurricane cannon to evaluate the home run-resistant windows. We shot baseballs from the cannon at an angle and speed that would recreate the power of a home run.
Our tempered glass weathered the hits best because it’s more durable 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 shoot a baseball out of the park.
In Wrigley’s case, we determined the baseballs would be going at about 60 mph upon hitting 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 strong, tempered glass in your Pella windows and doors.
It’s great for homeowners who want an additional level of protection from their windows or patio doors. Or those who are developing the next great baseball player.
Look at the strengths and highlights of Pella tempered glass options:
- Strong glass similar to what is used in car windows.
- Used where damages from broken glass are a concern.
- Usually shatters into small, square parts 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 find out more about impact windows and if they may be right for your home, call Pella of Shrewsbury at (508) 925-7149. Or, request a free, in-home consultation online.
