"fight fire with fire",
the plastic tabs on the hood insulation are supposed to melt in the event of an upper-engine fire, and allow the pad to fall onto the fire and cut off any oxygen that can make it's way to the vicinity of the flame.
fortunately, there are not many cars that come with this type of hood insulation anymore due to manufacturers quickly finding out that in MOST cases it will end up doing absolutely nothing more than accelerating the spread of fire over the intake and fuel rails, which could lead to more disaster.
The insulation is created to be a heat barrier for one that would need to open the hood, as the hood can get EXTREMELY hot to the point of scalding skin really bad when attempting to open it.
At least that's what I've been told by the fire department when I had the experience of having the local fire marshal, for some reason, sit in on our driving lessons class while we watched piss poor videos of some dude in an FC who drove at 200km down a highway that was packed full of kids chilling for no apparent reason and went onto the shoulder and ran over everyone in a quick swoop.
His advice was "it doesn't do much, so if it's old, just remove it. they are expensive, and should have been covered in flame-proof aluminized fabric from the get go"
