Blackout To Large Tempered Insulated Glass?

[suntint]

Glass is large but tempered. Largest units might be 45 or more SF each. What do people think of the chances of breakage?

I doubt you will get any breakage

Absorption is somewhere around 90%. If half of that window gets sunlight, that is a ton of stress. I wouldn't do it

It's a crap shoot. With so many variables, you never know. Tempered takes alot of stress, so, you SHOULD be ok. Variables - Shading, definately.....If there is a chip near the edge that could cause a stress point, Sure........ it is all up to you.

Thanks all for the help. They really want blackout. Going to ask them to sign a waiver

[Guest ridiculous]

a waiver sounds like a smart move

No way in hell.

Even with a waiver, the customer will feel disappointed, should they break. I would suggest something else. Why not a decorative film? Does the light have to be completely cut out? There are alternatives to blackout. You could print black on white frost on the interior facing side and reduce the risk.

For what it is worth, We have put black out on tempered units per customer request,more times than I can count. I have never had a tempered unit break to date. Im sure it is possible but in order to get glass to temper, It has been heated far in excess of the film will do. Im Just remember free advice is worth what you pay for it.

look what us auto tinters do to it with heat guns ...

another reccomendation is to put it on the exterior. this reduces the issue of breakage greatly.
