trick is to dump the heat to air this is how insulators work: have a chemical structr
of heat. If you can't vibrate, you can't take in heat, so it gets dump to atmosphere

Shuttle heat tiles / Apollo heat shield weren't so much insulators as HEAT REJECTORS

this is not correct. Even rigid semiconductors have phonons as well. @Warlord_Ralts

e.g., S, being indirect band gap, REQUIRES vibration to recombine holes/e- /2
