Security film on residential windows

[mfish123]

Hopefully this isn't too off-topic but figured this would be a good place to get the opinions of security-minded folks.

Does anyone have extensive knowledge? I did some research and looks like 3M makes some quality film that can be use for residential use. I even called a few certified installers.

My hang up is in the attachment systems and the differing opinions I get from different installers and folks on various forums.

From what I gather if the film isn't securely attached to the frame it's not really helping. Some opinions are that you can use it without the attachment system and it still adds strength. The other opinion is that it would actually make it easier to break in because one good whack to the window will make the whole pane come out as one nice neat square with no jagged edges that may cut the burglar / slow them down.

Other opinions are that you can use the attachments system but it sounds like it's really meant for commercial applications where you have a nice thick frame for the adhesive structural caulk to bond to. Sounds like residential window frames just aren't thick enough for the bonding system to properly adhere to.

Any opinions / experiences are greatly appreciated!

I have a ton of security film and did a decent amount of research. Lots of residential installers will tell you that you don't need attachment. Seems to be about 1/2 true. With plate glass and no attachment, the film will slow the bad guys down. With tempered glass the security film makes it easier for the bad guys to get in. Attachment is messy and time consuming, so many installers try to just skip it. I found this company's demo really helpful:

Wow I think he tinted my 4Runner. 10 years on and it still looks perfect. It looks like he's branched out.
