The original experts in incorporating oven door glass

Our founder, Herbert E. Mills, patented the oven window back in the 1940s. Today, Mills Products continues to create new innovations in appliance construction and engineering to meet the changing needs of the oven industry.

We manufacture oven windows for both self-clean and non-self-cleaning ovens with several choices of glass to maximize oven cooking efficiencies. We can design in-house or work from your existing design to find opportunities to reduce manufacturing costs and improve end-product quality.

With customers that include the biggest names in appliances, we’ve built a reputation as the go-to source for high-end, complicated designs.
