Guardian has invested tremendous resources toward continuous improvement in glass performance in solar heat gain, U-value, and other measures. As a result, the specification and use of SunGuard Advanced Architectural Glass continue to grow in the commercial construction market. We offer a wide range of products that:
The science of sputter coating
Historically, there have been two ways to apply coatings to glass. During the “online” Chemical Vapor Deposition (CVD) process, also known as "pyrolytic coatings", the coating is applied during float glass production. The “off-line” process occurs after the float glass is produced, using a Magnetron Sputter Vacuum Deposition (MSVD) coater, commonly known as "sputtered coatings". In general, the MSVD process offers more coating options and improved solar, thermal and light-to-solar gain options than the pyrolytic process.
To produce Advanced Architectural Glass, Guardian uses Magnetron Sputter Vacuum Deposition (MSVD). By using various gasses, such as argon or nitrogen and oxygen, and by layering metallic and dielectric layers in different sequences, we can produce a wide variety of coatings to meet most design and performance requirements.
The SunGuard advantage
SunGuard’s post-temperable coatings provide enhanced solar and thermal performance compared to typical pyrolytic low-E coatings and can be heat-treated and fabricated locally by independent Guardian Select Fabricators.
In short, Guardian’s patented SunGuard coatings can significantly improve the supply chain of commercial glass, providing shorter lead times, enabling fast-track job completion and allowing independent Select Fabricators to stock standard sizes of SunGuard Advanced Architectural Glass.
