About Us

Cat-i Glass Manufacturing can trace its roots back to Elgin Precision Glass (EPG), founded by Carl Jaynes nearly 50 years ago. EPG started out producing automotive air conditioning sight glasses in a barn. Thirty years later, key members of EPG became Cat-i Glass Manufacturing and continued to add greater diversification, expanded products and additional capabilities.

With its core being made up of former EPG employees, Cat-i Glass today is one of the largest technical flat-glass fabricators in North America. A key to our growth is our company philosophy of being engineering-driven and utilizing this specialized expertise on behalf of our customers. Cat-i Glass' emphasis on sales, engineering and customer consultation provides our customers with unprecedented ability to obtain the highest value - quality products, no unnecessary costs and short lead times.

As we have for five decades, our company still fabricates products for sight glass, with the capabilities for hundreds of other products in markets such as aerospace, display, instrumentation, lighting, medical, military and scanners.
