How Glass is Coated
Manage solar heat with energy efficient glass
All surfaces reflect, absorb and transmit heat. Guardian low-emissivity (low-E) glass helps control the transfer of heat to help make buildings more comfortable, energy efficient and filled with natural light. As one of the world’s largest glass coaters, Guardian offers numerous low-E solutions that can achieve the proper balance between light and heat.
How it’s made
Technological advances in the last three decades have produced systems and equipment that can coat glass with razor-thin, neutral coatings. These coatings are made with extremely thin layers of metallic oxides and other compounds to achieve specific optical and thermal properties. Depending on the layers used, coatings can manipulate light, reduce heat gain or loss, and achieve a desired color or aesthetic.
Watch the videos below to see how Guardian adds low-E coatings to our glass.
Solutions for any climate, any setting
No matter the location or application, Guardian low-E coatings can help meet your expectations for light, comfort and sustainability. We offer high-solar-gain coatings designed for cold northern climates, and low-solar-gain for hot southern climates. Explore our solutions for residential and commercial spaces below.
