Almost every hotel I've been in has had an enormously heavy door that bangs when it closes. Now, I've been to many homes, offices, and retail outlets with solid doors that have a definite pull-back to ensure closure. But only hotels seem to have that enormous 'slam' that resonates through the hallways.
Is there something I'm missing or is it all in my head. Why do hotel doors have to be so cumbersome? Maybe there are standards for 'star'-qualifications.
EDIT for clarification (as requested): Hotel room doors, almost universally, is what I am referring to. Even with sound-dampening hallways, they are almost always very cumbersome. I understand fire-proofing, but that can be done with less noise. Is there a reason beyond that?
