Thermal system solar controller COOL-LITE® XTREME 70/33

Product description
COOL-LITE® XTREME 70/33 and COOL-LITE® XTREME 70/33 II, respectively the annealed and to-be-tempered version, are extremely transparent triple-silver solar-control coatings that admit abundant natural daylight while blocking approximately two thirds of solar heat. They provide neutral colour rendering and clarity on façades, reducing summer overheating without significantly affecting visual comfort.

Benefits & Applications

• Very high visible light transmission to maximise daylight
• Neutral aesthetic in transmission and in both internal and external reflections
• Low solar factor to reduce cooling loads
• Low Ug-value for heating energy savings
• Consistent appearance and performance between annealed and to-be-tempered versions for façade compatibility

COOL-LITE® XTREME 70/33 & 70/33 II are designed for high-end commercial and public buildings where maximum daylight and controlled solar gain are required. Increased natural daylight supports occupant well-being and productivity. Typical applications include: offices with large glazed façades, healthcare facilities, educational buildings, galleries and retail spaces.
