EVERLAM™ COOL, our no-compromise solar control solution

EVERLAM™ COOL is a new generation of high-performance PVB film using nanoparticles technology and designed to give laminated safety glass more efficient solar heat control properties. It uniquely combines an excellent protection against infra-red radiation with the advantage of allowing light in while preserving the natural colors of what we can see through the glass.

EVERLAM™ COOL key features at a glance:

  • Constantly high Light-to-Solar Gain ratio (up to 1.7) with tunable solar heat gain coefficient as low as 0.3;
  • Color neutrality;
  • Low haze;
  • Low reflection of visible light (< 7%);
  • Significant and sustainable energy savings.

As for all its products, EVERLAM™ COOL benefits from EVERLAM’s excellence in customer and technical support.

With EVERLAM™ COOL, true colors shine through

EVERLAM™ COOL is a long lasting material and unique in that it preserves colors seen through the laminated glass. Whether looking from inside out or from outside in, natural colors can shine.



Other products that control solar heat often distort colors and at dusk or, on a dull day, make you feel as if you were in a dark cave. And some even increase the risk of glass corrosion over time.


EVERLAM™ COOL delivers high Light-to-Solar Gain ratio



The graph shows that EVERLAM™ COOL allows a high visible light transmittance even when 70% of the solar heat is blocked.

As a superior solar heat shield solution, EVERLAM™ COOL delivers high Light-to-Solar Gain ratio (up to 1.7), or LSG, defined as the ratio of the Visible Light Transmittance (VLT) to the Solar Heat Gain Coefficient (SHGC). A higher LSG ratio means that a lot of light can enter a room while a high proportion of the related heat is kept out. EVERLAM™ COOL filters infra-red rays of 1,300 to 2,500 nm. 

EVERLAM™ COOL’s LSG ratio can be adjusted for different applications. For example, vertical windows will favor a maximum of light coming through whereas in roof applications, the emphasis can be placed on heat filtration.
