There are many codes and guidelines on how an exterior door is installed and constructed but not so many, virtually none, for interior doors. Take into consideration the injuries that could come from slamming doors on someone’s fingers for example. That is why installing some pinch protection hardware in the door frame might be a clever idea. It is also very important to think about the means of exiting a house in case of an emergency. One example of restricted egress from a room could be an office or media room without windows and a door with extra locks because of security concerns. Also, think of the height and width of each door, make sure each door can be easily walked through and there are no obstructions.
It’s also important to look at the function of each door. Due to an uneven floor or foundation, or if the installation of the door was not performed properly, this could affect the function of closing and opening of the door. Another thing to check is the surface of the door to see if it is finished with paint or varnish, which would keep moisture from warping the door.
These are some things that you can remember while looking at each interior door of a home.
