ᐅ Difference Between Apartment Door and Soundproof Door

Hello everyone,

I am currently looking for interior doors and apartment entrance doors for our three-family house. At the moment, my favorite is "Westag" in the "CPL Arctic White" option.

I have two questions regarding the doors:

1. Door frames for interior doors and apartment entrance doors have a sealing profile. However, door frames for apartment entrance doors apparently have a sealing profile with sound insulation (what is the difference?) and a soundproof strike plate. How does a soundproof strike plate differ?

2. For the bathrooms (with washing machines) and storage rooms in the apartments (including the controlled residential ventilation unit), I am considering using soundproof doors. For these, I can select the door leaf option "sound insulation with bottom door seal." In your opinion, would this make sense? (Possibly without a keyhole yet). Or should I completely do without it, or even choose the better door frame?

Best regards

I had quite a bit of trouble with soundproof doors, especially because of the controlled residential ventilation system. There needs to be a gap of at least 1 cm (0.4 inches) under the door to allow airflow.
For some doors, I have soundproofing that includes a slit at the height of the door bottom rail, which the manufacturer says blocks sound but lets air pass through. Well, in the end, I found it to be a waste of money and wouldn’t do it again.

For the washing machine, I didn’t install any soundproofing, and you can only hear the spin cycle—and only if I’m sitting quietly and relaxing. During normal daily activity, even the spin noise gets drowned out.

Now, there is the solution of installing supply and exhaust air vents in every room without overflow areas. This, of course, means much more work and use of materials. It’s all a matter of priorities...

Does this also apply if there is no vent (supply and/or exhaust) in the storage room? The mechanical ventilation unit should be self-contained.

Okay, then the same should apply to the bathroom regarding the exhaust of the mechanical ventilation system with heat recovery.

I should have thought of that from the start. Maybe the noise level of the mechanical ventilation system with heat recovery isn’t that bad after all. We’ll have to see.

Here, this is also mandatory in the utility room (I do not live in Germany) because it is a room that can be entered, and without a ventilation grille under the door, there would be insufficient air flow. Whether the risk of suffocation is realistic, I don’t know. However, the ventilation grille is standard here and must be complied with. I have my washing machine in the utility room without soundproofing, and that is not an issue.

If you don’t have air exchange with other rooms, you won’t have a problem. However, in that case, you should also avoid using the utility room for drying.

As with any noise issue, the most important question is how sensitive you are, and the second most important is how the rooms are arranged in the house. It would be inconvenient, for example, if the washing machine is running late at night and someone needs to sleep right next to it. On the other hand, I find it less of a problem if you can hear the washing machine a little bit while working in a home office.
