SGG COOL-LITE is a solar control glass manufactured by depositing a coating of metallic oxides by magnetically enhanced cathodic sputtering under vacuum conditions onto clear or body-tinted glass. This coating gives the glass its solar control properties and its distinctive appearance.

There are many types of SGG COOL-LITE coated glass:

  • SGG COOL-LITE SKN a solar control glass range which gives excellent selectivity while retaining a neutral appearance.
  • SGG COOL-LITE K a selective solar control glass with low-E properties
  • SGG COOL-LITE ST is unique in that it can be toughened and curved after the coating has been applied.



  • Windows in traditional facades
  • Curtain walling
  • Exterior structural sealant glazing
  • Exterior bolted glass assemblies
  • Double-skin applications
  • Cladding of external walls
  • Overhead and atria glazing

The most appropriate glass is selected using 2 criteria:

  • Solar control performance: relative to the amount of direct sunlight, the orientation of the facade and the area to be glazed, the specifier can select the best compromise between the light transmittance (LT) and the amount of solar energy entering the building (solar factor g). Overhead glazing should generally have a much lower light transmittance than facades.
  • Appearance (when viewed from the exterior): the aesthetic appearance of the glass (colour, intensity, reflection) depends on 4 factors:
    • Orientation of the building
    • Surrounding environment
    • Glare
    • Amount of direct sunlight

 The final choice must be made after viewing samples of the proposed glass types in their intended location.



Solar control: energy saving and more economical use of air conditioning.

Improved "visual comfort" by reducing glare.

Multifunctional glazing: when assembled into double-glazed units, SGG COOL-LITE can become a multifunction glass, for example providing enhanced safety, security or comfort (thermal or acoustic).



  • More environmentally-friendly cooling solution with less need for costly air-conditioning or blinds.
  • Gently filters light to reduce uncomfortable glare from direct sun rays, whilst still allowing in plenty of natural light.
  • Excellent thermal insulation to reduce the need for internal heating during colder months.



  • Very selective glass combining high light transmission and low solar factor / shading coefficient
  • Solar control: energy savings and more economical use of air conditioning
  • Improved visual comfort by reducing glare, while keeping natural light
  • Low-E property energy savings in both hot and cold climate.
  • Environmentally friendly products thanks to less CO2 output of the buildings



  • Energy savings for air conditioning
  • Large range from transparent to darkest on clear, green or blue glass
  • Easy to store, handle and process coated glass
  • Temperable and bendable glass
  • Possible combination with SGG PLANITHERM® on face 3 for a more efficient thermal insulation
  • Can be used as single glass


The following substrate glasses are used for SGG COOL-LITE coated glass:

  • SGG PLANILUX clear glass
  • SGG DIAMANT extra clear glass
  • SGG PARSOL body-tinted glass

Using an extra clear glass emphasises the neutrality and transparency of high performance solar control glasses.
Using a body-tinted base substrate will offer a vibrant reflected colour.
Some coatings give a coloured reflection even when applied to clear glass. This is the case with the SGG COOL-LITE STB 136 and STB 120 coatings, which have a distinctive bluish reflection.
A neutral glass always has a slight greenish, bluish, or greyish residual reflected colour. The neutrality of the glass must be checked using a sample of the proposed glass in its intended location.
Certain SGG COOL-LITE coatings can be applied to the reverse face of SGG BIOCLEAN self-cleaning glass.

  • SGG COOL-LITE coated glass produced and processed in Saint-Gobain Glass factories and subsidiaries complies with the requirements of European standard BS EN1096.
  • SGG COOL-LITE ST and SGG COOL-LITE CLASSIC comply with the requirements of class B of standard BS EN1096.
  • SGG COOL-LITE K and SK comply with the requirements of class C of standard BS EN1096.
  • Exterior structural sealant glazing: processors and installers must check the compatibility of sealants with the SGG COOL-LITE coating and their suitability for use in exterior structural sealant glazing in accordance with EOTA (European Organisation for Technical Approvals) ETAG002.

The suitability of SGG COOL-LITE CLASSIC and SGG COOL-LITE ST coatings for use in exterior structural sealant glazing has been tested, in accordance with ETAG002, with Dow-Corning DC993 and DC3362 silicones covered by an ETA (European Technical Approval).

These tests do not apply to SGG COOL-LITE K, KT and SK coatings as they must be edge-deleted before assembly into double-glazed units
