A few years ago, the NZ government got all schools to have their windows made safe, by retro-fitting safety film. The film chosen was 3M 7-mil. Why this film was chosen is questionable, as the "benefits" are surplus to requirements. A 4-mil film qualifies for human impact standards. 7-mil is more to deter forced entry. Anyway, taxpayers money wasted, as usual.
One of the problems using 7-mil film is that it has to be pre-cut and consequently you get bad fits. Not a problem, as the film is clear. It becomes a problem, if another, tinted film needs to be applied later. Not really recommended, but it happens.
Today, we had to remove some 3M-7mil clear safety film. The schools were sold the film's unique properties of not being able to be torn, a "smart" trick 3M uses to promote this film. However, the film we removed was not the one "sold" to them years ago, because it was as easy to tear as any safety film. Someone pulled a fast one?
I have visited numerous schools where this film was installed, and the quality of workmanship has mainly been shocking! Due to the fact that the installers were offered very little (we declined the work when asked) inexperienced sign-writers were installing this difficult film type, with the expected results.
My point: Bureaucrats get sucked in, we pay. Nothing new.
This site should be interesting material for anyone considering having their windows tinted!

I would have never thought about having schools get safety films. Now thinking about it, I think it's a great idea. I can't imagine a better place to help protect kids by having safety films. I hope they install them in more schools. http://www.glasstintingwa.com.au/residential-window-tinting/security-safety-film/
