Shoutout to the old guy at the supply house who changed my mind on glass breaks
I was picking up some wire in Tacoma last week and got talking to this retired installer, Frank. He said he never used a glass break sensor in a house with double-pane windows... said the air gap messes with the sound profile and gives you false alarms. I always just slapped them in anywhere. He showed me on his phone, this study from like 2012 where they tested it. I've been doing this for 7 years and never heard that. Has anyone else run into this, or do you just use a different sensor type for those windows?

My old boss in Seattle had the same rule. We used shock sensors on double-pane jobs instead. That Frank guy knows his stuff.

Honestly, I've been putting glass breaks in houses with double-panes for like 10 years and maybe got two false alarms total. People act like the air gap is this huge deal but unless you're in some crazy noisy house it just works. Frank's study from 2012 is old news too, sensors have gotten better since then. I wouldn't overthink it unless you're getting calls every week.
