Fingers developed after years? Or at the time of install?


Recommended Posts

Film installed 23 years ago according to the homeowner. She says the fingers only recently appeared... within the past 1-2 yrs.

 

From everything I know, these would have formed at the time of install and not 20 some odd years later.

 

True? Or is it possible they are new'ish?

This happened on 3 panes out of all those done. (I didn't count, but I'm going to guess about 25 panes) 

 

I'm more curious as to the possible timeline... not really the cause. Just whether or not fingers could develope years after the windows being tinted.  :chin

I've got a couple large windows that have long lines like these that almost look like the glass cracked but hasn't.   It happened years after the job was done.  I think it is delaminating like was said.  Can't hardly see from the outside.

I agree with the de-lamination part.  I don't see why this would be any different than automotive film doing the same thing.

Film is made in layers, often multiple layers to get peak performance.  The fact that it took this long is a testament to that film type.  It lasted that long before failing. WOW! :gasp
