The XENIUM XPremium Ceramic IR window film. The densely packed nano-ceramic compounds used in their construction give the film very high heat rejection and immunity against fading, making this our most functional and color-stable window film to date.  The XPremium / Ceramic IR Film series has an even higher IR rejection of up to 95% on all VLTs, and it contains no metalized layers and will not interfere with electronic signals. The XPremium / Ceramic IR film series keeps the interior cool while providing a beautiful black exterior that matches the factory tint.
