Protective coating COOL-LITE® XTREME 50/22 II

exteriorfor facadefor glass

Product description COOL-LITE® XTREME 50/22 II is a heat-treatable triple-silver solar control coating designed for architectural glazing. It delivers a neutral appearance with high selectivity (2.24), approximately 47% visible light transmission and a low solar factor (~0.21), balancing daylighting requirements and solar heat reduction for commercial and premium building façades. The product must be tempered (suffix II) to achieve the stated performance and aesthetics.

Benefits & applications

• Neutral visual appearance in transmission and internal/external reflection
• Very low solar factor to reduce cooling loads and overheating
• Low Ug-value potential for heating energy savings when used in IGUs
• High selectivity suitable for offices, healthcare, education and high-end façades
• Typical uses: external façades, overhead glazing and other applications requiring heat-treated/toughened glass
• Also available on ORAÉ® low-carbon glass to combine performance and sustainability
• Product is being phased out and is replaced by COOL-LITE® XTREME 51/23 II

Appearance COOL-LITE® XTREME 50/22 II provides colour neutrality across viewing angles with mid/high light transmission paired with a low solar factor and low reflection, making it well suited to modern architecture with large glass areas and warm climates.
