Sinclair Glass has a long history in the glass business. Located in Northeast Indiana, our company was once one of many glass companies in this area. While many have simply disappeared, Sinclair has been able to change with the times and transform the business into a thriving enterprise. In 1988, Sinclair Glass was purchased by Gavin Mair who previously worked for the company and now serves as CEO. Since then, our business has expanded by ways of new equipment, increased efficiency, and growth in new and existing markets.
