Sinclair Glass is a specialty glass manufacturer based in Northeast Indiana, serving industrial and commercial clients across North America and beyond. With over 80,000 square feet of manufacturing space operating multiple shifts, we produce custom glass components that combine durability, functionality, and design. Our expertise lies in precision bending, slumping, tempering, and decorative glass processes — including patterned, colored, and our signature antique seedy glass — all crafted to meet the unique demands of high-performance products. Whether it's curved safety mirrors or artistic installations, we bring decades of experience to projects that demand more than ordinary glass.

We partner with manufacturers across industries — medical, aviation, lighting, mining, aquariums, furniture, and more — to deliver tailored solutions with speed, precision, and a personal touch. Founded decades ago and transformed under the leadership of Gavin Mair and now his son Andrew Mair, Sinclair has grown through innovation, efficiency, and long-standing partnerships. If your product needs glass that goes beyond flat and ordinary, we’re ready to help bring your vision to life.
