Controlled residential ventilation in a thin ceiling - soundproofing?

Hi,

I currently have a small "problem". I want to embed my controlled residential ventilation system directly into the filament ceiling. This is basically not a problem and is almost standard today anyway. But now I don't want every pipe to go through the ceiling into the utility room, but want to embed the air distributors directly and only have the 2 DN160 pipes for supply and exhaust air go through the ceiling into the utility room. I find this solution nicer and cleaner. I have now looked a bit for distributors for the filament ceiling, but have not found anything useful so far. There are distributors from some suppliers that are only 10 cm high and would therefore fit. However, these distributors are not insulated. The question is whether you even need that if these things are poured into the ceiling anyway? The sound-insulated distributors are always about 17 to 20 cm high. That gets pretty tight with our ceiling (24 cm total, 5 cm filament slabs + 19 cm concrete) or you no longer have sufficient concrete coverage. Maybe one of you has already had experience with this or knows about it.

I need 2x 8x75 distributors. Main connection DN160. The ventilation system will be a Viessmann vitovent 300F which is connected directly to the air-water heat pump.

Thanks in advance.

Best regards Daniel

You don't do that, you have to tackle it sometime. There are, for example, distributors from Helios that you mount on the wall, the pipe outlets are then at ceiling level and from below you connect with the 160 pipe.

thank you for the answer.

Question: what do you have to do there again? The pipes are in the ceiling anyway, and there is nothing else at the distributor. Only air passes through there.

do you happen to have a picture of the distributors from Helios?

Now, however, I don’t want to run every duct through the ceiling into the utility room, but want to embed the air distributors directly and only have the 2 DN160 pipes for supply and exhaust air through the ceiling into the utility room. I find this solution nicer and cleaner.

You need corresponding recesses in the Villigran ceiling, and then you can place and embed any distributor box there. As far as I know, this is standard as well?

The distributors should remain serviceable, therefore it is not standard practice to embed them in concrete - I have never seen that before either.

Here is a picture for the level between screed and tax consultant, but it can also be placed in the tax consultant.

Hello

With us, it looks like in the first picture. That's how I meant it with embedding in concrete.
