Certain Pella® windows can halt 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 ensure glass remains intact. We use our hurricane cannon to fire the wood, which moves 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 find a solution that could halt home runs from Major League Baseball teams.
When Pella was approached to help outfit 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 reconstruct the force of a home run.
Our tempered glass withstood the hits best because it’s more durable and safer than generally used annealed glass.
All About Physics
It requires 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 case, we learned the baseballs would be going at about 60 mph upon impact with windows.
But we went above and beyond and checked impact resistance up to 100 mph.
More Benefits of Tempered Glass in Pella® Windows
Even if you’re not thinking about an MLB home run hurling at your residence, there are a lot of reasons to select strong, tempered glass in your Pella windows and doors.
It’s ideal for homeowners who want an extra level of protection from their windows or patio doors. Or those who are raising the next great baseball player.
Consider the advantages and highlights of Pella tempered glass options:
- Toughened glass like what is used in car windows.
- Used where cuts from broken glass are a concern.
- Usually shatters into small, square parts 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 discover more about impact windows and if they may be right for your home, call Pella of Portsmouth at 603-427-0677. Or, request a free, in-home consultation online.
