Requirements for an apartment entrance door

Sound insulation for apartment entrance doors

Noise causes stress and is considered pollution. Therefore, a minimum level of soundproofing is required by law for apartment entrance doors. The “requirements for the structural soundproofing of door elements” are defined by DIN 4109. This includes the door leaf, frame, and seal, which are fully certified. The sound insulation classes are determined in the laboratory and given a sound insulation test value (RW, P).

Sound Insulation Classes

Sound insulation class I has an index of 32 dB Rw, P and is especially suitable for doors leading from stairs to corridors. A 37 dB Rw P-value is maintained for sound insulation class II. Sound insulation class III with a test value of 42 dB Rw, P is recommended for doors leading directly from the stairs to the living room.

Since sound waves penetrate even the smallest openings, a floor seal is essential for a good apartment entrance door. The floor seal is included as standard with most apartment entrance doors.

Apartment entrance doors must at least correspond to sound insulation class I and almost always have a floor seal.

Apartment entrance doors directly leading to the living room from the corridor should be equipped with sound insulation class III.


Climatic stability for apartment entrance doors

With different temperatures and humidity between the corridor and the apartment, rapid warping of the apartment entrance door may occur. Climate classes, therefore, indicate the temperature range for which particular doors are suitable.

The climate class thus describes the durability ( warp resistance ) of the door. This is important when a cold, damp corridor is separated from the warm, dry apartment.

With an apartment entrance door in climate class II or III, you can not only actively counteract the warping of door elements but also save energy.

Burglary protection for apartment entrance doors

An apartment entrance door should have sufficient burglary resistance to protect your apartment from theft and keep uninvited guests away.

Burglary resistance is defined by the Resistance Class (RC) – also known as Resistance Class (WK).

The classes are standardized according to DIN EN 1627 and are externally monitored, checked, and certified through a standardized test. The door is subjected to a test break-in attempt. The entire door element is constantly tested, including the door leaf, frame, lock, fittings, and hinges. Depending on how long and with which tool the door withstands the attempted break-in, it is assigned a resistance class.

For apartment entrance doors, it is recommended to use at least RC 2.

Fire and smoke resistance for apartment entrance doors

In apartment buildings, protection in the event of a fire is primarily ensured by an apartment entrance door. To prevent the passage of fire, fire doors are self-closing. The combination with a smoke resistance function (RS) is essential in apartment buildings. Fire protection doors must also be installed with smoke-resistance properties in long corridors, stairwells, and escape routes.
