  • Offices and commercial buildings.
  • Industrial buildings.
  • Curtain walling facades.
  • Schools and hospitals.
  • High-end conservatories and skylight glazing.


SGG Cool-Lite Xtreme 50/22 from Saint-Gobain Glass is a high performance solar control glazing. It is a triple-silver layered solar control glass offering an excellent selectivity of only 2.27. Ideal for use in commercial glazing where light transmittance is important but the need to keep solar heat out in the summer months, and retain internal heat in the winter months, is also a factor. SGG Cool-Lite Xtreme 50/22 is suited for all types of commercial buildings where large areas of glazing are required.


  • SGG Cool-Lite Xtreme 50/22 has the highest selectivity of 2.27 available from Saint-Gobain Glass.
  • The level of natural light is very high at 50% while the solar heat gain is extremely low with a g-value as low as 0.22.
  • Excellent U-values of 1.0 W/m²K.
  • A high degree of neutrality both in transmission and exterior reflection.
  • Available in a 'to be toughened' version.
  • Ideal for large façades and atria glazing where the neutral coating allows light through but reduces heat transfer through the glass.


  • Offices and commercial buildings.
  • Industrial buildings.
  • Curtain walling facades.
  • Schools and hospitals.
  • High-end conservatories and skylight glazing.


SGG Cool-Lite Xtreme products meet the durability requirements of European Standards EN 1096-1 and -2, Class C.
