More Than Just a Window Glass Manufacturer

An American Tradition

Homeowners and contractors alike take comfort in the familiar. So it’s no surprise that for many, Vitro Architectural Glass (formerly PPG glass) has long been the brand you can rely on for residential window glass.

Founded in 1883 as America’s first successful glass manufacturer, PPG has been advancing the science of residential glass performance longer than any company in the nation. In 1934–long before the idea of “green” building came into vogue–PPG introduced the world’s first environmentally-oriented architectural glass, which is still widely used on office buildings, hospitals, schools and other commercial structures today.

A mere decade later, PPG unveiled Twindow®, the industry’s first double-paned insulating residential glass with the promise to “keep homes warmer in the winter and cooler in the summer.”

Together, We See Further

At Vitro, we know the key to our success lies in the strength of our partnerships. With a foundation formed on trust, teamwork, and shared excitement, the possibilities for impactful innovations in glass are truly endless. In October 2018, we introduced our new identity to the world. After all, we have a reputation for working together and looking ahead. Now, that reputation becomes our identity.

The Promise Continues

Now, nearly 70 years later, amid a growing global emphasis on energy savings and sustainable building, Vitro glass remains more dedicated to those ideals than ever. Current Vitro glass brands such as Solarban® and Sungate® glasses are among the most environmentally advanced residential glass products in the world.

Developed in Vitro glass laboratories and formulated with highly sophisticated, proprietary coatings, Vitro glass window glasses are specifically engineered to block solar heat gain in the summer to help lower air-conditioning bills and trap heat in the winter so furnaces run less often.

What’s more, windows with Vitro glass provide the clear glass look that so many homeowners demand for natural outdoor views and the abundant daylighting that make living spaces brighter and more comfortable.
