tint_audiopros Posted March 13, 2008 Report Share Posted March 13, 2008 The main panes were about 35 sq.ft. each, all sealed units 1/4" daul tempered. Well its been about a year since we installed a 50% daul reflective on these windows. All of a sudden this winter 2 thermal breaks. Well these windows are not cheap about $1000 ea. & the manu. only covers up to $500 per unit. What do you do? Link to comment Share on other sites More sharing options...
Guest vclimber Posted March 13, 2008 Report Share Posted March 13, 2008 Tempered? No way, must be NSI. Did they go at the same time? What did the break look like? Link to comment Share on other sites More sharing options...
tintlife Posted March 14, 2008 Report Share Posted March 14, 2008 Could be pre-existing knicks insinde the frame. What kind of frame system is it in? Investigate the area. Is there road work, construction, landscaping, etc.? Film is the usual scapegoat but I've seen a few situations where other factors are to blame. For example a window I did cracked and after some detective work I found where screws had been drilled threw the frame and knicked the glass when they boarded up for a hurricane. Be sure though if you redo it to put a disclaimer on it! Link to comment Share on other sites More sharing options...
tint_audiopros Posted March 14, 2008 Author Report Share Posted March 14, 2008 Tempered? No way, must be NSI. Did they go at the same time? What did the break look like? One after another 2 weeks apart. Let me know what you think. Thanks for the info. & recommendations. Let me ask would you pay up & over what the manu. covers or leave it up to the customer Link to comment Share on other sites More sharing options...
Guest vclimber Posted March 14, 2008 Report Share Posted March 14, 2008 Are you sure that is tempered glass? Link to comment Share on other sites More sharing options...
Ryker Posted March 14, 2008 Report Share Posted March 14, 2008 no way that is tempered glass. It is a single crack. Tempered will basically explode under the film. It will be held together but it will be blown up. Link to comment Share on other sites More sharing options...
Guest vclimber Posted March 14, 2008 Report Share Posted March 14, 2008 The other problem is that thermal stress fractures never originate near the corners so the high point has to be the origin and it does not look like it projects 1-2" at 90 degrees from the glass edge... My guess is annealed glass with a clamshell. Link to comment Share on other sites More sharing options...

tintlife Posted March 14, 2008 Report Share Posted March 14, 2008 pull the vinyl back and see if it has already been damaged near the start of the crack. It just takes a minute and could save you $$$$ Link to comment Share on other sites More sharing options...
Tinitman Posted March 14, 2008 Report Share Posted March 14, 2008 Clamshell or exterior stress Link to comment Share on other sites More sharing options...
