This film is composed of 3 layers of ultra thin Ceramic.  Just as Ceramic is the only element that NASA uses on the heat shields of the Space Shuttle it is the element of choice that Huper Optik uses to achieve the incredible performance of this film. Be very cautious of other window tinting companies offering “Ceramic” films.  If it’s NOT Huper Optik, it is a inexpensive variation of their patent.  Want more proof, we ask you to “Google” Ceramic window film and you will see many sites all about this incredible film.  This film series comes in 4 shade levels: 30%, 40% 50% and 60%.  If you main concern is to block as much heat as possible, this film has your name all over it.  We invite you to our showroom for a complete demonstration of the true performance of this product.
