About us


Guarding the world with our glass

Glass is a naturally sustainable product made of simple materials. We take pride in our longstanding tradition of making glass products that help our world and the people in it. We’re committed to producing safe, reliable glass solutions, operating a healthy workplace and using our resources efficiently throughout the world. In 1993, we made this philosophy public by establishing our first environmental policy, and we’ve never looked back. Guardian Glass is a true champion for the environment.

We share your commitment

A longstanding member of the U.S. Green Building Council (USGBC) and withan ENERGY STAR® certification, Guardian products save energy and help earn LEED (Leadership in Energy and Environmental Design) points. We’ve invested millions globally to create some of the cleanest float glass plants in the world, and we operate in full compliance with all environmental laws and regulations. As a company, we innovate and collaborate to find ways of achieving economic growth while reaching our ultimate goal of sustainability and global environmental safety.

A better world starts with what we do

As leaders in the world of glass, Guardian Glass also needs to lead the way in environmental protection. We have implemented policies on air and energy, waste and hazardous substances, water efficiency and recycling. Worldwide, we have 16 plants that are ISO 14001 certified, consistently meeting the strictest international requirements and the highest industry standards. However, our focus on social responsibility takes us one step further. As a company, Guardian Glass is committed to protecting this planet and the people on it, building a more sustainable life with glass.
