Guarding the world with our glass. Glass is a naturally sustainable product made of simple materials. We’re committed to producing safe, reliable glass solutions, operating a healthy workplace and using our resources efficiently throughout the world.

We share your commitment. As a longstanding member of the (USGBC), Guardian products help 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 strive to operate in full compliance with all environmental laws and regulations.

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.


Our latest advances come from a long tradition. At the heart of our research and development is the Guardian Science & Technology Center (STC), where our scientists and engineers work together to develop new glass coatings, processes, formulas and technologies. We are committed to creating products that achieve your goals and improve quality of life.

Progress is measured in atoms. Our researchers determine which combination of individual atoms will optimize glass to create the right blend of color, heat, insulation and light transmission. While the atoms are so tiny they appear invisible on the glass, these coatings have a substantial impact on buildings.

Our breakthroughs get put to use. Our team of engineers turn great formulas into superior products that can be manufactured around the world.

The possibilities are endless. We are constantly thinking about new ways to use glass. Drawing inspiration from other industries and using design thinking, we are envisioning how glass can make the way we work, play, learn and live better.
