The door is one of the most important inventions of mankind. It was the door that often served as reliable protection against apartment thieves. Actually, most of its existence, humanity used mainly only the front door, and did not betray much importance to the interior doors. However, this is understandable, because great duties are imposed on the front door, while interior ones serve mainly for the interior.
One of the options for such interior elements are interior doors, that is, those doors that are located in the doorways between the rooms. The most important role of such doors is to distinguish between rooms. Agree, if you had no door to the toilet in your apartment and it would be constantly open, you would be uncomfortable. There is a giant number of interior doors. It is worth noting that according to the constructive features they are divided into sliding, folding, pendulum and swing. You can continue to continue this list, but it is clear that such elements of the interior there is a giant amount, even by such a feature as a constructive feature. Glass doors are used where solitude is not particularly important, but it is important to convey the light. That is, such doors will not be used for the toilet, or baths, but in the room that goes on the sunny side, the use of such doors is most justified.
