According to IWFA, Safety film ranges in thickness 4 mils to upwards of 21 mils and thicker. Somehow, for automobile window use is recommend between 4mil to 6mil thickness. Window film above 6mil may cause disrupt to your power window in 1-2 years time. Some car manufacturer already facing this problem few years ago and only experience shop will aware of this issue.
However we find a lot of shop offering 4-5mil thickness safety film to customer, but they tell the customer is 6-8mil. Guys, thicker safety film is not the selling point, laboratory on physical performance of safety film is the selling point.
In theory, 7mil thickness film provides slightly better smash resistance compare to 5mil, infact it is not much different in safety performance and costing. In Malaysia, safety film come with solar control performance. The different of price is normally due to different heat rejection. According to Raytech report, the metal/ ceramic coating on the film for heat rejection performance is so expensive in USA, on the other hand, the costing for the thickness of the film between 4-7mil is about the same.
