Save the Windows - Home-Run Resistant

Save the Windows. Pella windows were created to resist even the toughest conditions.


Built in 1909, this historic gem is right behind Wrigley’s left-field bleachers, 450 feet away from home plate. Its prime location means it has been peppered by home-run hits since the ballpark opened in 1914. And now, thanks to Pella and the Cubs, 1032 W. Waveland is ready for the season – with new home run-resistant windows.

The Pella Reserve line features intricate, historic detailing – with each window precisely crafted and custom-built. The windows created for 1032 W. Waveland match the building’s historic design flawlessly. And they provide modern, high-performance features, such as improved noise reduction and stronger glas

What a Cannon Taught Us To test our home run-resistant window, Pella retrofitted the hurricane cannon to launch baseballs at an angle and speed similar to a home run hit. Tempered glass was proven to withstand hits best because it is stronger and safer than annealed glass (commonly used in windows).



How Fast the Baseball Needs to Fly What does it take to launch a baseball out of Wrigley Field? A speed of over 100 mph to send it far away from home plate, and a height of more than 100 feet to put it over the bleachers.



The Baseball's Impact Speed Pella applied physics calculations to determine that the ball would be traveling at about 60 mph when it hit the window. Then we went beyond and tested for 75-100 mph.











The Baseball's Trajectory Wind resistance and gravity naturally affect the trajectory of a baseball. But weather, changes in wind direction, time of day, and even air moisture content can influence a baseball's path.
