By reusing glass cullet

One of the ways we save energy while re-utilizing “waste” is by incorporating cullet into our processes.

Reusing recovered glass cullet One of the ways we save energy while re-utilizing a byproduct is by incorporating cullet into our processes. Cullet is broken or rejected glass that is added to new materials, heated to a liquid state and floated on a bath of molten tin to produce a perfect ribbon of glass, while providing a multitude of benefits not just for our business, but the environment. Glass cullet, which melts at a much lower temperature than sand, is recyclable and reduces our overall energy needs. On average for every 10% of cullet we use in our processes, our energy demands are reduced by up to 3% (Guardian, including primarily using internal cullet generated from float glass manufacturing, on average runs between 18% and 20% cullet, dependent on quality and availability). The use of cullet reduces CO2 emissions since cullet requires less energy to process. Utilization of cullet lowers our dependency on virgin materials, saving resources like sand, soda ash and limestone.

By contributing to energy star-compliant products

We design with energy performance in mind, from the early stages.

 

Contributing to Energy Star-compliant products

We’ve developed a range of Guardian ClimaGuard® residential low-emissivity (or low-E) coated glass products to help keep homes comfortable in different geographic zones and environments, as well as help meet Energy Star® requirements for energy efficiency (North America only). These low-E coatings help reflect infrared light to keep heat inside where it’s needed during the winter and outside in the summer. From high-solar-gain coatings for homes that endure cold northern climates, to low-solar-gain coatings that benefit homes located in hotter southern climates, ClimaGuard windows utilize the thinnest layers of metallic oxides and compounds that can keep homes comfortably warm or cool in even the harshest environments. And for commercial construction, our Guardian SunGuard® advanced architectural glass products also utilize low-E coatings for superior solar control and energy performance in installations around the world.

By commiting to the resource efficiency

How we’re finding more energy efficient ways to make the products people value.

Committing to the Resource Efficiency At Guardian Glass, we are committed to using our resources more efficiently. One example includes the GulfGuard float glass facility in Saudi Arabia where we’ve made a concerted effort to reduce carbon emissions through several energy reduction initiatives. By installing variable-frequency drives to control the speed of the cooling fans on our float and pattern glass lines, we’ve achieved an annual energy savings of more than 550,000 kWh. By replacing all warehouse roof lamps with high-efficiency LED fixtures, we’re projecting an annual energy savings of nearly 750,000 kWh once complete. And we’re working on installing new mechanical seals on all our major cooling water pumps to reduce motor energy consumption by 10% and create a projected annual energy savings of more than 1 million kWh.

By making declarations for health and environment

We’ve developed and published environmental product declarations (EPDs) specific to our glass facilities in our Europe, North America and AMEI regions based on third-party verified Life Cycle Assessments (LCA).

 

Making declarations for health and environment

At Guardian, we’ve developed and published environmental product declarations (EPDs) specific to our glass facilities in our Europe, North America and AMEI (Africa, Middle East and India) regions based on third-party verified Life Cycle Assessments (LCA). EPDs present transparent and verified information about the lifecycle environmental impact of products. Guardian EPDs are developed specific to the region where the glass is manufactured since facility-specific information is collected to quantify the environmental impact of a product. Each EPD is reviewed and approved by a third-party testing and validation service. We then publish these declarations to support various stakeholders including architects and designers by providing our customers with the information they need to achieve credits in green building ratings systems like LEED and BREEAM. Additionally, we share our health product declarations (HPDs) in North America for both our flat and processed glass products as a standardized way of reporting the material contents of our glass building products. Guardian Glass is also very excited to share our most recent addition of Product Lens™ Certifications for our AMEI region flat glass and processed glass products. UL’s Product Lens™ Certification, developed in partnership with MBDC and Cradle-to-Cradle Product Innovation Institute, is a next-generation transparency tool that shows a substance’s hazard data in context using exposure indicators along the four phases within the life cycle of the product.

By making glass safer for birds

What is Bird1st UV-coated glass?

Making glass safer for the birds

Every year, millions of birds make their annual migrations across long stretches of land, often passing through towns and cities in their migratory paths. This can be challenging in populated areas with large buildings, because birds have difficulty determining reflections from reality and often mistake reflections of trees and sky with the real thing. To reduce the impact potential between migratory birds and buildings, we developed a unique coating for our Guardian SunGuard® coated glass as a way of integrating collision deterrence. We call it Bird1st UV-coated glass, and it utilizes a patent-pending UV striped coating that’s visible to birds, but nearly invisible to humans in dry conditions. This product is not only tested effective by the American Bird Conservancy, but can help builders earn LEED Pilot Credit 55 (bird collision deterrence).

Please be aware that Bird1st is manufactured in the United States of America and therefore may not be readily available in your region.
