Enjoy unexepected transparancy.

COOL-LITE XTREME 70/33 and 70/33 II is clearly getting the balance right between solar heat and light.

COOL-LITE XTREME 70/33 and 70/33 II are the latest innovation in high performance solar control coatings. So building occupants can benefit from generous daylight, while minimizing discomfort from overheating in summer.

These triple silver coatings are applied to PLANICLEAR or DIAMANT by cathodic sputtering under vacuum conditions.
They offer the most neutral aesthetics and highest level of transparency with outstanding performances on annealed or “to-be-tempered” glass.
The selectivity achieved is 2.12. A beautifully clear breakthrough.


Two versions of the product are available to adapt to all requirements for security in facades:
- XTREME 70/33 for annealed glass
- XTREME 70/33 II for tempered glass

Size and thickness Standard On demand
Size 6,000 mm x 3,210 mm up to 18,000 x 3,210 mm
Thickness 6 mm, 8 mm 4,10,12 mm



COOL-LITE XTREME 70/33 & 70/33 II feature extremely transparent and selective solar control coating for use in high-end commercial buildings, when maximum daylight income and optimum indoor thermal comfort are desired.

Commercial Offices

It can significantly reduce solar heat gain in offices featuring large glazed facades.

Healthcare Sector

It maximises incoming daylight for optimum health and well-being.

Education Sector

It increases indoor comfort for effective learning environments.

Other Public Spaces

It creates welcoming spaces ideal to admire art work or enhance shopping experience.

More natural daylight indoors translates into improving the mood, health and productivity of the people who live or work there.


Hight performance, higher than expectations

  • - High level of transparency and neutral aesthetics in transmission, and both in internal and external reflections
  • - High light transmission (70%) or maximum daylight
  • - Low solar factor (0,33) for reduced cooling loads
  • - Low U-value (1.0 W/(m2.K) for heating energy savings

Handling & Processing

For optimum performances and aesthetics, the following instructions are to be observed:

  • Thermal treatment: XTREME 70/33 II is delivered with EasyPro and must always be tempered or heat-strengthened before assembly into a double or triple glazed unit. XTREME 70/33 must be used annealed and assembled into double or triple glazed unit.
  • Lamination: both can be laminated, the coating not being in contact with the PV layer (please note: XT 70/33 II must be heat treated before lamination).
  • Other: both versions of the coating must be edge deleted and should be positionned on face 2 of a double or triple glazing unit.
