Hello!
I'm trying to find out what type of construction my facade has. I lack drawings, and it was carried out independently with the help of a professional.
I bought an older house with a facade replaced in 2012 in this way: "Plaster on mineral wool mounted on fiberboard/OSB board and then an air gap against the wood frame."
There is no open gap/ventilation/vent in the lower edge of the facade. Is this a modification of a single stage sealed facade?
Why is there an air gap if there is no opening?
Best regards

When was the house built?
If it's mineral wool and wood, then it is not "sealed." Tightness is achieved by, for example, EPS, which Myresjöhus has experienced.
Funny that the air gap doesn't have openings though
But one should distinguish between: single-stage facades and single-stagesealed facades. The former is not really a good construction either, but it has worked and been used for hundreds of years.

With the building year 1916, the frame is probably log-timbered. What you refer to as an air gap could be a simple framing to create a flat surface for the plaster. I would not call it a risky construction.
Thank you for your responses! Interesting.. It seems like the facade is something in between then.
The inspector hasn't found any leaks and therefore only noted it as a "risk." But still warns of a risky construction from a moisture perspective since the underlying board is made of organic material and the air gap is closed.
Could it be an idea to open up the air gap at the bottom, install an opening for ventilation? Then the only remaining problem is that the material inside is organic.
