Door to the utility room/technical room

Hello everyone,

today we went to get quotes for the garage door and the garage door entrance, and now the question arises whether we should install a T30 door or at least a sound-reducing door in the utility/technical room.

The access to it is in the hallway next to the living room door. Between the rooms is a load-bearing wall, which should absorb quite a bit, but what about the doors? To the living room, there will only be a full glass door, and whether it is always closed is questionable. But a normal room door to the technical room will hardly be able to block the noise from the washing machine and technology, right?
It doesn't have to be a fire protection door, since we only have a heat pump. But besides the heat pump, the photovoltaic system, the controlled residential ventilation, and as mentioned, the washing machine and dryer will also be in this room.

How have you handled this?

: what was making such a hell of a noise on your acquaintance’s inverter?

I can’t tell you - but I didn’t follow up either. He just gave me the advice to pay attention to it and mentioned that they were so disturbed that the inverter had to be moved. So I also always specifically looked at the dB number.

Hello,

if I understand your question correctly milke, you mean the door from the utility room to the garage. Of course, a T90 door is required there; from the utility room to the hallway, a normal interior door is sufficient.

No, we meant the door between the utility room and the hallway. The garage does not have direct access to the house. But we will probably also pay attention to the dB numbers.
