COOL-LITE XTREME SILVER II is an innovative two-in-one coated glass, that combines a reflective, silver aesthetic (Rext 30%) with extreme solar protection (solar factor 0,25).  It features outstanding selectivity (2) and reinforced thermal insulation (Ug 1,0 W/m2.K.); providing unbeatable aesthetics, comfort and energy performance.

COOL-LITE XTREME SILVER II is a unique solution, developed to create iconic buildings that meet energy regulations. The reflective, silvery finish of this coated glass allows the building facade to blend with and reflect its environment.

COOL-LITE XTREME SILVER II is ideal for facades (curtain walls, windows band facades, punctuated facades, etc.), in commercial buildings and high-end residential building with larger window surface. The combination of reflective silvery aesthetic and extreme performances allows the product to be used alone on single skin facades. In DGU, no need to combine it with another coating to reach the highest energy efficiency & ultimate aesthetics.



We spend a lot of our time indoors.  There are many factors that influence how we feel inside a building, including the overall aesthetic, successful interior design, balanced noise levels or acoustics and natural levels of light.  A well designed and constructed space can enhance our sense of comfort and wellbeing, helping to improve health and productivity; important across all building sectors.  It's the balance of the key factors below that provides overall comfort.

  • High light transmission to create brighter interiors and year round natural lighting
  • Low solar factor to reduce the burden on costly air-conditioning
  • Excellent U-value of 1.0W/m2K making it the ideal product for energy savings and improved thermal insulation
  • High degree of neutrality both in transmission and exterior reflection

COOL-LITE XTREME can be used to create more comfortable interiors by reducing overheating in the summer and heat loss in the winter, while retaining an extremely neutral appearance.



  • COOL-LITE XTREME SILVER must be tempered.
  • COOL-LITE XTREME SILVER can be assembled into an insulated glazed unit with the coating on face 2.  Edge deletion is required.
  • COOL-LITE XTREME SILVER can be laminated with the coating not in contact with the interlayer. STADIP, STADIP PROTECT and STADIP SILENCE are Saint-Gobain laminated glass technologies.
  • COOL-LITE XTREME SILVER is supplied without EASYPRO.

Safety glass, which will be either toughened or laminated, depending on where and how it is being used, protects from the risk of serious injury caused by accidental breakage or impact. When it breaks, it breaks safely.

Types of safety glass have different benefits:

  • Toughened glass fractures into small relatively blunt fragments upon failure, preventing cutting and piercing injuries associated with large shards of annealed glass.
  • Laminated glass contains a polymeric interlayer, designed to retain sections of glass in the event of fracture, and so prevent shards separating from the main body of the glass. Laminated glass also provides an enhanced level of protection where there is a change in level, and so a risk of falling, or where there is a potential for objects to fall from height onto occupied areas below.

The type and level of safety can vary from one project to the next. Saint-Gobain Glass always recommend seeking advice from one our Technical Specification Managers (TSM) before you proceed with a particular glass type.



Security rated glass can help protect against break-in attempts or vandalism by delaying, or even preventing, penetration through the glass.

The STADIP product range comprises of laminated glasses that offer additional security benefits.

COOL-LITE XTREME SILVER can be supplied with STADIP technology.  We recommend seeking advice from one our Technical Specification Managers (TSM) before you proceed.
