Products/Applications

Guardian’s EcoGuard^® Glass products provide superior performance for solar energy systems. Our wide array of offerings include:

EcoGuard Float is a low-iron float glass designed to maximize solar energy transmission. EcoGuard Float offers optimal energy and light transmission for photovoltaic energy systems, Concentrating Solar Power (CSP) mirrors, concentrating photovoltaic systems, solar thermal applications and more.

EcoGuard Pattern is a low-iron annealed or tempered pattern glass designed to maximize solar energy transmission and enhance photovoltaic module performance.  EcoGuard Pattern is used in photovoltaic energy systems, solar thermal collectors, greenhouses, lighting and other applications requiring high solar transmission.

EcoGuard Mo is Molybdenum coated glass designed to optimize the conductive characteristics of photovoltaic systems that use copper indium sulfide (CIS) and copper indium gallium diselenide (CIGS) solar cells and is available in several different glass thicknesses and levels of conductivity.

EcoGuard TCC is coated glass designed to optimize the conductive characteristics of photovoltaic systems that use CdTe solar cells and is available in several different glass thicknesses and levels of conductivity.

EcoGuard Solar Boost Laminated and Monolithic parabolic mirrors utilize Guardian’s highest performing solar glass, EcoGuard Float, to provide best in class solar reflectivity and enhanced durability. Designed specifically for CSP parabolic trough systems with industry leading performance specifications.

EcoGuard Solar Boost Laminated and Monolithic concentrating flat mirrors also utilize EcoGuard Float to provide industry leading reflectivity and durability. Designed specifically for concentrating solar thermal applications.

EcoGuard Solar Boost High Temperature concentrating mirrors offer all of the same features and benefits of our other solar boost products, but are designed for concentrating solar applications where secondary reflectors are used.
