Experiences with roller shutters and decentralized ventilation system

Hello,

Since I am now considering whether we actually need a ventilation system, I have received an offer from the construction contractor for a decentralized ventilation system with integration in the roller shutter box.

It is this system ROKA-THERM[emoji768] 2 RG AIRFOX[emoji768] L

Does anyone have any knowledge about this?

Regards, Daniel

Ask him if you can test it somewhere where it has been installed. Especially whether noises are disturbing is very subjective.

He has not installed it yet.

Hmm, so a pig in a poke... I would really listen to a sample first... especially roller shutter boxes make good resonators...

Will be difficult,
Is relatively new on the market.
Sounds great in the brochure, of course, but who knows [emoji3]

Well, they must have patterns somewhere even if they are new...
