Safety glass panel COOL-LITE® SKN 145

solar controlinsulatingacoustic

Summary
Double glazing with COOL-LITE® SKN 145 provides very high solar protection (solar factor g = 0.22) while maintaining moderate visible light transmission (TL = 41%). Solar-control glass with high selectivity and good thermal insulation. Typical composition used for calculations: 6-16-4 with coating on face 2.

Selection / environmental and performance arguments

• Energy savings
  • Reduced electricity for lighting and air conditioning: selectivity > 1.86
  • Reduced heating losses (Ug = 1.1 W/m²·K)
• Thermal comfort: limits the risk of summer overheating and avoids the sensation of a cold surface in winter (suitable for conservatory roofs).
• Visual comfort: good natural light for the given level of solar protection and good access to outside views.

Applications

• Rooflights or glazed roofs
• Large glazed façades oriented south or west in hot sunny climates, or façades without additional exterior solar protection (e.g. high-rise building façades)

Advantages

• Slightly shimmering bluish appearance, color stable and homogeneous at different viewing angles
• Very high solar protection (g = 0.22), reducing cooling needs
• High thermal insulation (Ug = 1.1 W/m²·K) to limit heat loss
• Enables large glazed spaces while preserving visual and thermal comfort
