Lifespan of a tint film is determined by its quality, i.e. its production technology, as well as by professional installation standards. It is not always easy for those who do not work in this field to assess the quality of a film and its installation at first glance, but the results of low quality production and inadequate installation will quickly become visible.



The film that starts to detatch and change colour after a while (usually turning purple) is a mark of bad quality. Such a film has bad performance specifications (especially heat and UV protection) even when new, and especially once it starts to age. The warranty period for installed films can't be the basis for differentiating between materials of higher and lower quality. Naturally, if no guarantee is offered, such a film and the service that installs it are definitely not a good choice.

High quality films manufactured using top-notch technology and a high professional standard in installation guarantee a long life span for the film. It is important to select a tint brand known for its quality and long tradition in production, as this will allow you to have confidence in the long life of the chosen tint. The largest manufacturers present on the European market are members of the European Window Film Association (EWFA), which imposes strict criteria on quality. This is a good starting point in your research of film choices.

We recommend LLumar films, characterized by their superior quality. With over 55 years of experience, LLumar is one of the most distinguished world brands of high performance automotive films. LLumar films are manufactured by Eastman Chemical company in the USA and UK, under strict surveillance and control, to meet all international legislation and quality standards (such as ISO 9000 and ISO 9001 certificates). Known for their patented scratch and corrosion resistant layer, LLumar films are resilient and require practically no special maintenance.

Once you have chosen a film brand, you need to choose a licensed installer service authorized to install your chosen tint. The best films demand the best installers, because even the highest quality films will not perform at their best if inadequately installed. LLumar authorized service and their certified installers have, at their disposal, the latest tools and techniques in installing window tints at the highest standard.

For high performance films installed according to professional standards, licensed installers will issue a written warranty. The warranty can cover a period from a couple of years to over a decade. Still, the authority issuing the warranty also matters. Check to see whether the selected installer has been licensed by the film manufacturer and how long is the tradition of the guaranteeing tint shop, because smaller shops open and close each day.

Certificates of installation for LLumar films can be issued solely by authorized LLumar tint shops, employing installers that have passed the manufacturer’s test. Black Glass is an authorized LLumar tint shop and the only LLumar Gold partner in Serbia, and all of Black Glass’s installers have passed the professional training and been issued LLumar certificates. The warranty for tinted glass in Black Glass is 10, 12 or 15 years, depending on the LLumar films installed. A written warranty is issued, guaranteeing that the film will not change in appearance or performance over time and that it will not detach.
