LANSING, Ill. (August 10, 2023) – A total of 274 people will lose their jobs as the Silver Line Building Products plant, located at 16801 Exchange Ave., winds down operations.
Calls and emails to the company, which manufactures vinyl windows and doors, were not returned for comment.
But a Worker Adjustment and Retraining Notification (WARN) letter sent from Cornerstone Building Brand Services, Inc. to the Illinois Department of Commerce and Economic Opportunity said the intent is to permanently close the manufacturing facility in Lansing.

The letter from Cornerstone Human Resources Vice President Juan Gallegos said employees “are expected to be separated from employment beginning on August 11, 2023, with all separations accomplished by no later than September 29, 2023.”
No reason was provided in the letter regarding why the facility, which opened in Lansing in 1997, is closing.
The letter said 194 employees at the facility are represented by Silverline IL Teamsters Local 731 Production and 12 by Silverline IL Teamsters Local 731 Drivers.
According to a list of job classifications included with the letter, the majority of jobs lost fall under various manufacturing/production technician categories.
A Silver Line Windows & Doors Facebook page indicated the location was hiring as recently as April 2022.
Lansing Village Administrator Dan Podgorski thinks the biggest hit initially will be felt by other businesses in town who were visited by Silver Line employees who bought food, gas, or other services in the village.
“Anytime you lose a large employer it’s gonna hurt,” Podgorski said.
But Podgorski said since Silver Line is a wholesaler, the effect on the village in regards to taxes will be limited.
“I don’t think we’re gonna feel a pinch in regards to retail sales tax,” Podgorski said.
