Solar control for creative applications

SunGuard Silver 20 coated glass helps deliver energy savings with a more reflective appearance. Its ability to reflect heat and solar radiation makes it a great product for hot environments and super-tall buildings—including the Burj Khalifa, the world’s tallest building.

Key features:

Uniform color: Sophisticated reflective appearance
Excellent chemical and mechanical durability: When compared to traditional sputter-coated products
Manufacturing options: Ready to be tempered, heat-strengthened, curved or screen-printed with approved enamels
Widely available: Guardian Select® fabricators can help you meet tight project deadlines
Single product: For both annealed and heat-treated applications
Easy to process: Does not require edge deletion
