COOL-LITE XTREME 70/33 is an innovation in high performance, solar control coatings. The triple silver coating is applied to PLANICLEAR as standard, by cathodic sputtering under vacuum conditions.

COOL-LITE XTREME 70/33 offers the most neutral aesthetics and high performance solar control.  The coated glass achieves a selectivity of up to 2.25.



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.


COOL-LITE XTREME 70/33 forms part of the Saint-Gobain solar control and thermal insulation range, which in combination with other products can also offer:

  • Noise reduction when used in conjunction or applied to STADIP SILENCE
  • Safety and Security when used in conjunction with products from the STADIP range


COOL-LITE XTREME 70/33 sets a standard in high performance solar control, whilst retaining the excellent neutral aesthetics associated with the COOL-LITE range:

  • High light transmission of 70% to help maximise daylight.
  • Low solar factor of only 0.33 which helps to reduce cooling loads and the potential requirement for air conditioning within a building.
  • Excellent centre pane U-value of 1.0W/m2K; delivering excellent thermal insulation and helping to drive energy savings.
  • High level of neutrality in transmission and exterior reflection.
  • The most neutral coating within the COOL-LITE range.

COOL-LITE XTREME 70/33 can be used to create comfortable interior spaces by reducing overheating in the summer and heat loss in the winter, whilst retaining market leading neutral aesthetics for facades and glazing.



  • COOL-LITE XTREME 70/33 can be supplied to-be-tempered or annealed. Where the product name includes “II”, this denotes that the coated glass must be heat treated, i.e. thermally toughened or heat-strengthened.
  • COOL-LITE XTREME 70/33 can be assembled into an insulated glazed unit with the coating on face 2. Edge deletion is required.
  • COOL-LITE XTREME 70/33 (II) 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 70/33 II is supplied with EASYPRO.



COOL-LITE XTREME 70/33 (II) can be supplied in a range of thicknesses and sizes:

Size: 6,000 mm x 3,210 mm (standard) up to 18,000 mm x 3,210 mm (on demand)
Thickness: 6mm, 8mm (standard).  4mm, 10mm, 12mm (on demand).

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 70/33 can be supplied on STADIP or used in conjunction with STADIP as the inner pane of an insulating glass unit, with COOL-LITE XTREME 70/33 as the external pane.

COOL-LITE XTREME 70/33 can be supplied on STADIP where an annealed option is desired.
