How Guardian’s Solar Management Glass (SMG) works to reduce light and heat

Guardian leads the industry with solar management glass (SMG) solutions. Our SMG series works to reduce light and heat in the vehicle by absorbing, reflecting or blocking the sun’s rays.  Compared to standard green glass SMG prevents a larger portion of the sun’s heat from entering a vehicle, thus reducing the overall solar load.  The resulting effect is a reduced load on automotive air conditioning units, a more comfortable cabin environment and reduced emissions.

Low-emissivity (low-E) coatings, microscopically thin metal layers that are deposited on a window surface, are used to help keep heat on the same side of the glass from which it originated.

Low-E coatings were developed to help minimize the amount of ultraviolet and infrared light that passes through glass without compromising the amount of visible light that is transmitted. It is also active in controlling the heat within the cabin. When the interior heat energy tries to escape to the colder air outside during the winter, the low-e coating on the window reflects the heat back to the inside, reducing heat loss through the glass. The reverse occurs in the summer, maintaining a cool and comfortable environment in the cabin.

Our Solar Management Glass manages solar energy and protects against ultraviolet radiation while providing a comfortable amount of visible light transmission. These innovative glass solutions provide both form and function and also give your vehicle the aesthetics you want. Additionally, our complex bending capabilities give customers a wide range of style options. We offer formulations for both laminated and monolithic systems as well. Applications include any vehicle opening that requires 70% light transmission, from windshields to side glass and rear glass.

Guardian’s Infrared Reflective Solar Control Glass (IRR) helps reduce the thermal load inside a vehicle. Rather than absorb heat, Guardian IRR  reflects the sun’s heat, achieving extremely low transmission levels. Guardian IRR can be used in any opening of the vehicle and has the option of being electrically heated to provide invisible de-icing.
