I live in an apartment where there is only one window and my main door which is glass sliding door and thus the entrance to my apartment. Where i live is pretty hot. Most people have their doors open etc due to this. Almost everyone here has their fan turned on all the time... its those fans on the top of the ceiling etc. People here turn on AC as well if its hot. For me, i don't turn my ac on much because i don't feel very hot though but thats me. Well i had notice that i had a cabinet where it has been breaking apart. Basically the back of it and the sides are tearing apart. I had not know the reason for this but someone tell me the reason is because i rarely have my windows opened. Can someone here confirm that if you don't have windows open, this could happen? I have lived in many different apartments and this never had happened every before. This is back in the US. I mean i understand hot weather makes things warmer etc but can it basically break things inside the house if no windows are opened for any air to get in for a long time? I do have the ceiling fan at high settings on almost all the time. This was months ago though. I'm located in Mexico and in my previous apartments here in Mexico, i never had this issue at all. I usually have ceiling fan open and ac on a few times but not that much as i don't need it. Another thing was recently i noticed the floor in my room is not only uneven... but its basically like a huge crack thats uneven in an area. This is on a specific area in the room. Like if you walk on that area, you notice thats like a crack. Thus the floor is not only uneven but you see a noticeably bump and theres a line like that in the room. I have never seen this before. In the picture i post, you can probably notice it i think... its on the 2nd line vertical around the area and extends upwards. Thus if you look at the right of it... no bump/crack at it. However few days ago we had to have some people do repair work on the AC and they did bring ladder and other things and had to stand on top of that exact area etc. Could this have possibly caused this bump/crack on the floor? My apartment is basically a 2 room open studio... though there is a door that separates the 2 rooms but its more like an open push door as oppose to a real door. And this crack is around the same spot where the guys put their ladder and other things on etc. Would that most likely be the reason? Or could heat cause this? The thing is someone in my building told me the reason the cabinet basically was tearing apart was b/c its so hot and thus things tear down. I didn't know this as i never had this happen before. But it did make sense. Can someone confirm this is true? But what about my floor then? Its basically like tile floor and this happened few days ago right after the guys did work on that area though so i thought that had to be a coincidence. Because if heat could cause this, why would it take that long for it to happen. I can't imagine heat could have caused this right or could it? But i do have the fan turned on in that room and the other room. I will ask the person i rent from on this but i wanted to know your opinion. 1. How would i be able to fix the cabinet parts tearing apart? It does look like i could stick it back together though. Would getting super glue be able to fix this? What exact type of glue would i need? Also in the last picture... its from the side of it. Can you all see how its like worn out as well like imagine a wet piece of paper? Its like torn like a brown piece of construction paper etc. 2. How would this be fixed with the floor? I had wondered could it be possible that the people who live under me could have caused it? Such that their fan or they hit something in the ceiling really hard which is why my floor is like this? The thing is i noticed this bump/even a few days ago and this was again right after when a few guys had to come over and do something with my AC and they put ladder in that area to climb up to it etc. Could they have put ton of pressure on it etc? It really feels like if i put lot of pressure on that area, i felt like it could break though i think that is exaggerating it a bit. Thanks.

I tear out a lot of ceramic tile counter tops and have always used cloth tarps to protect the floor. I'm running into more wood floors all the time and want to switch to something with more cushion. I have a few ideas like carpet runners, but that doesn't sound like the best. Anyone have something they use that works well?
