Quality control

We strive for quality in everything we do

Environmental Stewardship

We pride ourselves on being solution providers, especially in the context of environmental stewardship, which involves considering each stage of the life cycle – from the sourcing of raw materials for each product, through to its production,  application and end-of-life. Our approach to environmental stewardship is twofold – we strive to discover new and innovative technologies that improve both the environmental performance and effectiveness of our manufacturing processes and of our products. 

 

Stewardship in action:
explore the life cycle of glass

We also partner with glass fabricators and processors, architects, designers and suppliers, to create products and services that help meet their needs and project goals. We communicate information about the life cycle environmental impact and material health of our products as it becomes available.

As highlighted in our environmental priorities, we always strive to innovate and provide solutions that are a win-win-win for our customers, the environment, and society. And to truly be transformative in this space, we look to partner with suppliers, customers, and other key partners who share our vision.

Recycled glass content

We’re committed to improving the energy efficiency of our manufacturing processes and reducing our use of resources. One way to achieve these is to maximize the amount of glass cullet used.

Cullet Recycling

Cullet is broken or rejected glass which can be reprocessed – saving resources such as sand, soda ash and limestone. Having already been through the mineralization process, cullet melts at a much lower temperature than the raw materials, so the more cullet used, the more energy efficient the process. In fact, energy demand is reduced by approximately 3% for every 10% of cullet, and because less energy and fewer raw materials are used, this also reduces CO2 emissions. Recently we even conducted a pilot production in Europe that used 60% cullet – while still remaining focused on the quality of the glass.

Retrofitting the future

Retrofitting existing buildings, instead of constructing new ones, is now acknowledged to be a viable approach in reducing the resources used during a building’s construction.

Retrofitting the future

Guardian’s high-performance glass can play an important role in this, and the 225 Polk building in Nashville, Tennessee is one such example. SunGuard™ SuperNeutral 68 HT low-E coating on low-iron UltraClear™ glass helps deliver the energy performance requirements of a contemporary building, while preserving the look that helped make the building an important part of Nashville architecture.

Retrofitting the future

Glass innovation

Our architectural glass products have been contributing to the energy efficiency of buildings for many years and we continue to innovate at every opportunity – for residential and commercial projects. 

Glass innovation

Guardian ClimaGuard®, for example, is a residential low-emissivity (low-E) glass that helps keep homes comfortable in different environments – by helping retain the interior heat in colder climates and reduce solar heat gain in hotter climates. For commercial construction, the Guardian SunGuard® range also utilizes low-E coating technology for superior solar control and energy performance. All of which helps architects and designers to comply with important regional codes and standards like Energy Star® and IECC 2021, and regional certifications around the world such as LEED®, BREEAM and WELL.

Certifications, declarations and other programs

To support the sustainability goals of architects and designers, Guardian Glass offers several certifications, declarations and other documents to communicate transparent information about the life-cycle environmental impact of many of our products. 

Certifications, declarations, other programs

These programs help our partners meet increasingly stringent building codes, standards and certification schemes.  Examples include: 

Lastly, we’re proud to introduce our LEED® Green Associates™, in association with Green Building Certificate Inc (GBCI). Through rigorous certification and professional credentialing programs, GBCI drives the adoption of green building and business practices globally. Our new, dedicated associates have the latest knowledge about these building principles and practices – offering you expert support to help you meet specific LEED® requirements.
