Saint-Gobain Glass launches COOL-LITE® SKL 170: solar control glass to improve efficiency of complex facades
At Saint-Gobain Glass, our customers are central to everything we do, and we are constantly innovating to meet their changing needs and challenges they encounter.
In double-skin and closed-cavity façades, managing the space between panes poses challenges. Solar heat accumulation can cause overheating of blinds, faster component aging, and added strain on ventilation systems.
This issue is a costly design constraint for façade contractors and high-rise designers. Effective control of solar gains at the outer skin level is essential, achievable with a selective laminated coating that lowers cavity temperatures.
This launch of the COOL-LITE® SKL 170 is informed by these insights. It provides a solution that surpasses existing offerings, combining agility, technical expertise, and responsiveness to meet specific project requirements and deliver genuine added value.
COOL-LITE® SKL 170 is a highly selective solar control coating, specifically designed for use embedded in laminated glass, in position 2, against the interlayer. COOL-LITE® SKL 170 offers not only a neutral aesthetic, consistent whatever the viewing angles, but also high selectivity. This double silver coating provides a high light transmission above 70% and enhanced solar protection.
When used as the external skin of a Double Skin Façade (DSF) or Close Cavity Façade (CCF), it delivers:
- High visible light transmission (TL), maximizing natural daylight entering the building through such complex, multi-panel façades.
- A low solar factor, limiting heat build-up within the cavity, protecting the durability of blinds and allowing for reduced ventilation system sizing.
- A neutral, angle-stable aesthetics with low reflection, meeting both market expectations and local regulatory requirements.
Beyond façade applications, COOL-LITE® SKL 170 also brings clear benefits to other applications, including:
- Skylights and roof glazing, providing effective solar control while preserving daylight, particularly suited to large glazed roof areas where insulation demands are lower.
- Entrance structures and canopies, combining visual elegance with reduced glare and solar heat, commonly specified for public buildings, shopping centers, and transport hubs.
- Train station halls and atriums, enabling solar control in large open spaces while maintaining visual comfort and lowering cooling loads.
With this launch, Saint-Gobain Glass reinforces its commitment to continuous innovation, staying as close as possible to its customers’ challenge.
