Dear forum members,
Our walls are currently being built, and the masons could create a core drill hole for us so that the exhaust air can be routed through it later.
Additionally, a wall vent box will need to be installed. My question is, when is the wall vent box installed (after attaching the insulation or already now?) and how is the insulation protected from condensation? With expanding foam?
Maybe some of you have already dealt with this.
Thank you very much for your input.

Another question... the opening for the wall box will be about 150mm (6 inches) in diameter... do you need a lintel for that, or can you just drill it directly into the exterior wall?Drilling directly is fine.I just spoke with the plumbing company, and they are willing to carry out a core drilling for the exhaust wall box. However, I now need to obtain one fairly quickly, as they will install it during the work.
I had been undecided between the Naber flowstar GTS 150 and the Weibel, which was also recommended here. Since I need to get the wall box quite soon, I also found this one at Bauhaus: it is electrically controlled like the Weibel and is probably easier to source.

Could this perhaps be a good alternative as well?At least twice as expensive! Does it have to be electric?nordanney schrieb:
At least twice as expensive! Does it have to be electric?Not necessarily. But the Naber model has received many complaints about the mechanism eventually failing, for example, the vent no longer closing properly after some time. An electric version should work reliably at least as long as the motor remains functional. There is also an electric option from berbel for just under 400€, which would probably work as well.

However, there are many complaints about Naber products, saying that the mechanism eventually stops working, for example, that the opening no longer closes properly. I've been using it for about 1.5 years without any issues. So far, I can't share those concerns. It only cost around €130.
