Hello everyone,
I would like to get some opinions/facts on the following topic:
To achieve sound insulation or to prevent drafts inside a building (single-family house), it is possible to install a threshold at every door inside the house. This means that the finished floor level of the room the door opens into is about 2.5 cm (1 inch) lower. The door then rests on the threshold at the bottom, creating an (almost) airtight seal. For example: the hallway has a floor buildup of 17 cm (7 inches), while all accessible rooms into which a door opens have only a 14.5 cm (5.7 inches) floor buildup.
The question is: Is this a standard and recommended practice in new constructions nowadays, or was this mostly done in the past (1980s)? – I have seen it in a house from that period...
I am looking forward to your answers and opinions – thank you very much!

Doors should or can have a small gap when combined with controlled mechanical ventilation. Originally, the question was about soundproofing, where simple gaps are obviously counterproductive. To ensure air transfer even under higher soundproofing requirements, there are several options:
- Air transfer behind the door frame,
- Drop-down seals with an air transfer opening,
- Special transfer vents for wall installation.

In our case—we live two people in the house—we deliberately chose to forgo these measures and went with the simple option.
