Apartment entrance doors are used in rental homes and more family homes as internal entrance doors. They are also known as apartment doors or apartment closing doors and separate the common corridor from the privacy of your living space. As they are used as kind of second entrance door between the apartment and the corridor, internal entrance doors should be equipped with several additional functions compared to normal internal doors.
In this tip you get to know which four features you should keep in mind and why those are so important.
The correct insulation of the entrance door avoids deformation of the internal entrance door caused by high differences of temperature and humidity. This is especially important as the living space can be right behind the staircase or the corridors. As those two areas are normally not heated, the temperature and humidity difference in comparison to the living spaces is rather high and therefore the door leaf of the entrance door can be deformed. Internal entrance doors that are equipped with a high climate rate can prevent against deformations.
In the door leaf an aluminum layer is included, that helps to avoid that the door is deformed by high humidity and temperature differences up to 20 degrees. For internal entrance doors that are connected to unheated facilities like corridors it is important that the door has a high climate class (3). Hörmann equips apartment entrance doors with climate class 3 as a standard.

It depends if the entrance door connects the common corridor to the apartment corridor or directly to the living space of the apartment. In these cases, different sound insulation classes are recommended. If the entrance door connects living space and corridor directly, the noise protection class should of course have a higher sound insulating effect as with noise insulation class 3 to avoid sounds from outside.
If there is an apartment corridor in-between a lower noise protection class like class 2 is enough. Both classes are equipped with a bottom seal that lowers automatically when the door is closing. This provides additional noise protection and avoids that cold air from the corridor gets into the living space of the apartment.
Figure: If the apartment entrance door leads directly from the staircase to the living space, a door with sound insulation class 3 prevents against noise from outside. If there is an additional corridor between in the apartment, one class lower is sufficient.
As the apartment door is like a second entrance door, security against burglars is recommended. To provide high security feeling they should be equipped with RC 2 resistant class as an option. This is resistant against burglaries with simple tools like a screwdriver, pliers or a wedge for at least three minutes.
Doors that are equipped with RC 2 have a thicker door leaf, burglary resistant hinges, locks and proven security fittings. Apart from terrace doors, apartment entrance doors are the most endangered doors for burglaries according to the "security at home" police research report. Therefore the correct security equipment is especially important.

Spy-holes, automated locks and especially resistant surfaces make your door more appealing. Especially for multi-family houses spy-holes make sense, as you can have a look who is outside first, without opening the door.
To lock the door automatically when it closes a convenient motorized lock can be used in addition. An unlocked entrance door which would lead to the case that the insurance would not pay in case of a burglary will be past then. Additionally a motorized lock gives the door the opportunity to equip it with an drive to make it even more convenient and barrier-free when operating with a remote control or a wall switch.
As the apartment door is used regularly and more than once a day it is important that it is resistant and therefore the door leaf and hinges should be durable. The Duradecor surface by Hörmann is not only available for interior doors but also for apartment entrance doors and is especially shockproof, easy-care and insensitive against scratches and shocks. So your door will be long-living and visually appealing. The apartment entrance doors by Hörmann are available in many different designs and versions and can be adapted to the chosen interior doors, that they fit together visually. The external and internal view of the entrance door can be chosen individually that it can fit to the common corridor and the other doors as well as to your interior design and your interior doors.
