Vitro Architectural Glass

Unavailable Vitro Products & Alternatives

Occasionally, Vitro Architectural Glass (formerly PPG Glass) has found it necessary to discontinue products for various reasons, including scarcity of raw material supply, environmental requirements, low market demand or other operational considerations. This page lists products that are no longer manufactured by the company and, wherever possible, identifies an alternative.

Even though a product is no longer manufactured does not necessarily mean that the product is no longer inventoried or not available for replacement. When a product is discontinued by Vitro Glass, the company creates a special inventory supply, sometimes referred to as “attic” stock. If you need more information on a discontinued product, please contact your Commercial Account Manager or National Architectural Manager.
