And if you're renting, you're just **** out of luck.
Plus you have to have a good level of knowledge when buying these things, and have a contractor you really trust. I've installed some doors and uninstalled some doors. I've seen some of those thousand dollar plus doors that were no better than normal exterior doors; this means they can be removed with a flatbar or large screwdriver in less than a minute. Many can just be lifted straight off after taking off the top board. Even the most expensive are worthless if not installed with safety in mind. It really doesn't matter how strong the door is if the framing was never done right in the first place. Then if they aren't hung right, they are a fire deathtrap waiting to happen.
I took a security door off inside an old bank (being re-purposed as a theater) in less than thirty seconds with a pocket multi-tool and strong arms. It was never installed correctly, or had been re-installed incorrectly at some point.
None of this should be taken as an argument against good doors and windows.
