Not like fire alarms, I know they do. I'm talking about if you were to slip the lock on a door to get into a school at night, if a silent alarm or something might go off. If the school is poor and it doesn't have cameras, they probably won't have an alarm right?(if schools even have alarms.)
Reflective insulation has a metallic layer. This layer is subject to oxidation over time, thereby losing the reflective properties. The quality of the insulation and method of installation would determine if the reflective layer will last years, decades, or centuries.
