ᐅ Is a soundproof door necessary for the utility room? Any experiences?

Hello everyone,

Our builder has offered us a soundproof door from Hörmann, climate class III / sound insulation class 2 (RwP 37 dB).

We have an internally installed air-to-water heat pump, controlled mechanical ventilation with heat recovery in the utility room, and otherwise the usual installations including a washer/dryer.

Is a soundproof door necessary or useful in this case? It would cost us an additional 200 euros compared to a standard door.

What about the controlled mechanical ventilation with such a door? Would the air be able to circulate, or would the ventilation be affected?

What do you think?

Thank you

Regards

So, our machine is quiet, even at 1600 revolutions per minute. Quality and weight make a big difference...

You can buy a Miele for 1,000–2,000 euros and another one for the dryer, and then it’s the compressor of the heat pump after all. Or you play it safe and pay 200 euros for the SK2.

If I understand the original poster correctly, the issue is not about saving the €200 but whether the mechanical ventilation system will still work properly if they install this door.

He is asking both questions.

But why shouldn't the controlled residential ventilation system work?

Because this door apparently includes a perimeter seal, if I understand correctly. And if the door is cut slightly shorter at the bottom to allow air to flow from the hallway to the utility room, then these two requirements conflict.
Therefore, either you shorten it enough so that the seal at the bottom no longer functions, or you don’t cut it, but then the airflow will not work.

By the way, we have new Miele washing machine and dryer, and even though we didn’t choose the cheapest models, you can still hear these appliances. In my opinion, a soundproof door definitely makes sense. We also have a controlled mechanical ventilation system, and the door’s seal certainly helps reduce airflow between rooms. However, someone often goes into the utility room, so I don’t see any issues with that since the door isn’t closed all day. I would definitely install a soundproof door again—it’s amazing how much quieter it makes the space.

Best regards,
Sabine
