Product description
COOL-LITE® SKL 170 is a highly selective solar control coating developed to be embedded in laminated glass (to-be-laminated, coating on face 2). The coating features a double silver design to combine high visible light transmission with improved solar protection for complex façade assemblies.

Benefits & applications
COOL-LITE® SKL 170 delivers a neutral, angle-stable appearance and high selectivity, making it suitable for multi-panel façades where daylighting and solar control must be balanced.

• High visible light transmission (TL >70%) to optimise daylight in complex façades such as double-skin façades and close-cavity façades.
• Reduced solar factor to help lower cavity temperatures, extend blind lifespan and enable ventilation sizing savings.
• Neutral aesthetic with low reflection and stable appearance across viewing angles to meet architectural and regulatory requirements.

Other recommended applications:

• Skylights and roof glazing — provide solar protection while maximising daylight for large glazed roof areas.
• Entrance structures and canopies — reduce glare and heat gain while preserving visual neutrality.
• Large halls, atriums and transport hubs — control solar gain in expansive spaces to maintain visual comfort and reduce cooling loads.

Appearance
Designed for embedded use (laminated), COOL-LITE® SKL 170 provides a neutral, angle-stable appearance when laminated with the coating on face 2 in contact with the interlayer.

Technical information

• Range / substrate options: PLANICLEAR® (clear), DIAMANT® (extra-clear), ORAÉ® (low-carbon).
• Thickness range: 3 mm – 12 mm.
• Sizes: Standard jumbo 3.21 x 6.00 m and standard stock sizes.
• Processing: Available in annealed state; lamination required.
• Edge deletion: Coating edge deletion compulsory prior to assembly.
• Lamination: MUST be laminated with coating on face 2, in contact with the interlayer (embedded configuration) to achieve intended performance and appearance.
• Availability: Europe.

Performance
Compared with standard outer-skin coatings for DSF/CCF, COOL-LITE® SKL 170 yields a lower g-value while maintaining high visible transmission. Calculations indicate improved control of cavity temperature (up to -15 °C) and blind temperature (up to -20 °C) in typical façade configurations.

Tools & service
Manufacturer calculation and specification tools are available to model optical and thermal performance and support integration in complex façades; consult product literature and technical channels for details.

Sustainability & certification
COOL-LITE® SKL 170 is available on ORAÉ® low-carbon glass to reduce embodied carbon. The product is covered by a verified Environmental Product Declaration (EPD) and is Cradle to Cradle Certified® V4.0 Bronze.
