KSB Exterior Clear Windshield Protection FILM

KSB AK85 Exterior Windshield protection film is a transparent, durable film applied to the exterior of a vehicle’s windshield to provide protection against various hazards and damage. This film is made from a clear EPU material that is resistant to scratches, chips, and impact from road debris such as rocks, gravel, and insects. 

The primary purpose of windshield protection film is to prevent damage to the windshield and maintain its clarity and visibility. It acts as a sacrificial barrier, absorbing the impact of small objects and preventing them from causing chips, cracks, or other forms of damage to the glass.

In addition to protection against physical damage, KSB AK85 windshield protection films also offer other benefits such as UV protection, heat rejection, and improved aerodynamics. These films can help reduce glare, heat buildup, and interior fading caused by prolonged exposure to sunlight.

Technical Data Sheet



Performance Notes:

  • Performance results are calculated using Linshang Window Film Measuring Instruments, and are subject to variations within industry standards and only intended for estimating purposes. This data is provided for informational purposes only and are subject to normal manufacturing variances.

  • Performance results based on film applied to W (6mm) dear glass and a representative automotive glass with a base visible light transmission of 75%. Due to variations in glass performance. these values should not be used to comply with local tinting laws.


  • [1] VLT stands for Visible Light Transmission, -the percentage of visible light that passes through a window film or tint. It is to indicate how much light is allowed to pass through the film and into the interior of a vehicle or building. A higher VLT percentage means more light is transmitted, resulting in brighter interiors, while a lower VLT percentage means less light is transmitted, resulting in darker interiors.

  • [2] INFRARED ENERGY REJECTION (IRER) The percent of infrared energy (780 nm to 2500 nm) that is directly reflected and absorbed and radiated outwards. The higher the number, the more infrared energy reflected and absorbed and released outwards. IRER is the endorsed calculation method of IWFA.

The use of an automotive protective wax such as Turtle Wax, NuFinish, RejeX or Meguiar’s Wax is an essential part of the maintenance program for AK 85 windshield protection film. The wax will maintain the scratch resistance and water repellency of this film when it is used as directed. The wax also seals the film against bird droppings, bugs, oil, tar, grease, dirt and grime. The installer will apply an initial amount of the wax at the time the film is installed on the windshield. The vehicle owner should continue to apply wax to the windshield every month during the life of windshield film

How to replace the Auto windshield protection film?

The film can be removed by using a hard plastic or stainless-steel object (i.e. edge of a plastic credit card or stainless-steel blade) by simply lifting the film on one edge and then pulling, using slow and consistent pressure. Any adhesive remaining on the windshield can be removed with a non-caustic cleaner designed to remove adhesive. New windshield film can then be installed on the clean windshield. *Average replacement cost of an ADAS equipped windshield according to a 2018 study by AAA (American Automobile Association) and does not include related body work or recalibration of ADAS systems.
