Mechanicals infractions are quite common facade problems, especially in houses where small children live. It can be just a small accident during play with a ball, but that crack in the facade can stay forever. For this reason, before buying a particular facade material, it is worth considering whether that particular one is resistant to mechanical infractions and if not, whether it is difficult to repair.
The final problem is flammability. This problem is not common but before choosing a facade material it is worth remembering that highly flammable materials will burn much faster than non-flammable materials. The facade's function is to protect, so help to protect yourself with high quality materials. You cannot save money at the expense of a life.
