The building, which sits right behind the left field bleachers, is a prime home run target, and has had at least two windows broken by baseballs in recent memory, says Matt Waldren, an engineering specialist in Pella's test lab.
"We saw a need in the market, windows being broken, so we offered up a solution and the Cubs were willing to take that ball and run with it," says Waldren of the partnership.
Pella specified their Architect Series Reserve line, a window collection with a historically accurate look. The Pella team also upgraded the glass to a tempered option, which, after testing in a lab, was determined to be able to withstand the impact of home run balls.
"We went through and analyzed a lot of MLB statcast data, then we took that data and developed a test in our lab," Waldren explains. "We modified our hurrican cannons to shoot baseballs. We set up products and started shooting baseballs at them."
The design of the Architect Series Reserve windows allowed the projects certified installer, LaPelusa Home Improvement, Inc., to keep the historic interior window elements.
"We crafted a hybrid type of installation approach, where we took a full-frame exterior, but we decided to preserve all of the interior trim, molding and millwork, because of its history," Brian LaPelusa, the company's owner, explains. "Pella windows facilitates that by making a window designed to allow all of the inside molding and millwork to stay in place."
