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

200€ is basically nothing in construction costs, like ordering an ashtray as an extra for a new S-Class.

However, a special interior door between the hallway and the utility room is not necessary if the installed appliances are decent. We also have everything located in the utility room as you planned, and when the door is closed, you can’t hear anything in the hallway.

You might want to ask what the purpose of that door is. Since the door has to be vented at the bottom anyway for the ventilation system, an acoustic door only makes limited sense.

SK2 doors offer almost no sound insulation. We have installed them in the utility room, bathroom, etc. In the office, I have SK4 doors...there you really get peace and quiet...

It's not so much about the 200 euros. It’s more about the fact that the function of the ventilation system is being compromised.

Order it as well; there is a huge difference. The SK2 already includes a soundproof seal, and it works wonders.

You’ll be glad when the heat pump’s compressor starts running.

We also have a soundproof door, and it definitely makes a difference—washing machines are not exactly quiet during the spin cycle.

Best regards,
Sabine
