Thermal system solar controller COOL-LITE® XTREME 61/29

Product description
With COOL-LITE® XTREME 61/29 (II), architectural projects benefit from a new generation of high-performance solar control coatings. This triple silver selective coating provides an improved neutral appearance regardless of viewing angle, reduced reflection and outstanding performance for annealed and to-be-tempered glass.

Benefits & applications

• Neutral aesthetic in transmission and both internal and external reflection, aligned with architectural trends for colour neutrality, transparency and low reflection.
• Comparable performance for both annealed and to-be-tempered versions, ensuring consistent outdoor appearance.
• Energy efficiency: extreme selectivity to reduce energy demand for artificial lighting, heating and air conditioning.
• Indoor comfort: neutral appearance combined with strong thermal insulation and effective solar control for comfortable, well-lit interiors year-round.

Typical applications
Suitable for fully glazed facades in commercial and residential buildings requiring high solar protection without compromising aesthetics. Examples: offices; healthcare; education; other building types. Mid/high light transmission with low solar factor enables bright interior spaces while reducing reliance on shading systems and saving energy. Low reflection and neutral appearance match contemporary architecture with large glass panes, hot climates and renovation of historic buildings.

Appearance
COOL-LITE® XTREME 61/29 and 61/29 II deliver extreme colour neutrality at all viewing angles, low reflection levels and outstanding optical performance.

Environmental & certification
The product is covered by a verified Environmental Product Declaration (EPD) and is Cradle to Cradle Certified® V4.0 Bronze.
