Re: Lock makers that you can trust?
It's a lot easier to buttress against a push than to guard against a pull. Positioned right, even 65kg can resist quite a force. Once saw a TV ad for a little brass thing you stick in the floor that could take some serious abuse; odds are the door fails before it.
There are several reasons most home doors open inward. One is as mentioned to allow them to be barred or barricaded. Another is (with entry doors) to make it easier to escape hostile weather (with businesses it's usually the reverse; you want it easier to get OUT than IN due to the potential for crushes in an emergency).
