Which side entrance door (security / fire protection)?

Sure?

Good question

I tried to look it up and found no differences in the respective federal states. What I found is that it depends on where the fire protection door is to be installed.

Take a look:

*"Use of Smoke Protection Doors

Smoke protection doors must be installed where required by building regulations. According to § 35 paragraph 3 of the Model Building Code (MBO), if the exit of a required stairwell does not lead directly outside, the area between the required stairwell and the exit to the outside must have smoke-tight and self-closing closures. Furthermore, paragraph 6 states that in required stairwells, openings to basement floors, unfinished attic spaces, workshops, shops, storage and similar rooms, as well as other rooms and usage units with an area of more than 200 m², excluding apartments, must have at least fire-retardant, smoke-tight and self-closing closures. Openings from required stairwells to required corridors must have smoke-tight and self-closing closures. According to § 36 paragraph 3 MBO, required corridors must also be subdivided into smoke compartments by non-lockable, smoke-tight and self-closing closures.

If the closure of an opening is required both through a smoke protection door (RS) according to DIN 18095-1 and through a fire protection door according to DIN 4102-5 Fire behavior of building materials and components; fire protection closures, closures in elevator shaft walls and fire-resistant glazing, terms, requirements, and tests (e.g. fire-retardant, smoke-tight, self-closing closure), a door must be installed that meets both requirements, i.e., a fire protection door with smoke protection function.

Requirements for Smoke Protection Doors

To ensure that smoke protection doors close independently, door closers according to DIN 18263 Locks and building hardware - door closers with hydraulic damping must be used. Only hold-open devices whose usability has been proven are allowed. If smoke protection doors are located in publicly accessible corridors used as escape routes, they must not have lower stops or thresholds. Use suitability certificates (abP or abZ) must be available for fittings, handle sets, locks, and locking devices and the installation instructions for smoke protection doors must be observed. The building operator is responsible for the proper condition of the smoke protection door."

Fire protection doors are distinguished as follows:

fire-retardant doors = T30
highly fire-retardant doors = T60
fire-resistant doors = T90. Additionally, a differentiation is made between single-leaf doors (e.g., T30-1) and double-leaf doors (e.g., T90-2).

The fire resistance rating of a fire protection door depends on the building use and the requirement for the wall in which the door is installed. Glass integrated into a fire protection door must have the same fire resistance rating as the fire protection closure (e.g., T30 door with F30 glazing).


Personally, I do not find T90 doors expensive, but that is a matter of opinion. What is true, however, is that "nice" fire protection doors cost a lot of money.

That sounds very good and at a very reasonable price! So you don’t have any RCx at all? So it’s a "normal" locking cylinder?

We have RC2 on all exterior doors and windows - the front door, for example, is always locked five times and doesn’t have a lock to the outside at all. The garage door is protected against prying – anyone who really gets into the garage can easily get into the house as well. Therefore, I consider a normal garage door in T30 design with a good profile cylinder to be absolutely sufficient.

I also thought the offer was great – especially with installation, which is really tricky with the doors.

[I]Smoke protection doors must be installed where they are required by building regulations. According to § 35 paragraph 3 of the Musterbauordnung (MBO), if the exit of a required stairwell does not lead directly to the outside, the space between the required stairwell and the exit to the outside must have smoke-tight and self-closing closures.

Thanks Bauexperte for the information! However, our hallway/stairwell does have an exit to the outside. You can either go out through the front door or into the garage....

We have RC2 on all exterior doors and windows

Has this been taken into account in the heat calculation ("calculation according to the energy-efficient house" ...)?

Has nothing to do with it after all...?

RC2 also requires, in my opinion, a certain installation that deviates from the "standard." This makes the house less airtight or significantly increases the effort. Typically, steel brackets and masonry anchors are used. The installation manual provides more details. The effort to still build airtight is therefore higher. I would like to learn more about how it is actually done in practice (i.e., windows according to RC2 in the Energy Saving Ordinance or Efficiency House)... You could tell me how your windows are installed (or have been?).
