"single-stage sealed facades"?

[andypandy]

When they write about problems with single-stage sealed facades.
What kind of constructions are they referring to?

ha, now they have come up with a new name for the scandal to make the confusion greater. Just wondering if it's the journalists or those responsible who are so inventive
Last time I read about it, the description was: timber house with plaster facade without air gap. I guess it's the same problem with a different name.

It refers to plaster directly on foam plastic. That is, an undrained wall construction with plaster without an air gap. I've seen this term used since the problems began. It's probably more that journalists have previously made up other names because it sounded too technical.

It is render directly on cellular plastic that is referred to

Well, there are plenty of houses that have render directly on cellular plastic but do not have any moisture problems, and these are stone houses with glued cellular plastic and render on it.

To get problem houses, it's a wooden frame without an air gap and then cellular plastic on that which is rendered.

Exactly, it's just as Gladh says. The single-step method applies to wooden houses with a plastered facade, where the big companies thought it was perfectly fine to skip the air gap while having wooden studs underneath. The issue was brought to attention a couple of years ago, but within the construction industry, it has been known for even longer. NCC, among others, has been involved in renovations of newly built areas, while continuing to build new ones according to the same concept - often in the same area.

As shocking as the minced meat scandal. Everyone is aware of the problem but still claims to be outraged when the media wave hits.

Well, there are plenty of houses that have render directly on the EPS but don't have any moisture problems, and these are stone houses with glued EPS and render on that.

For problematic houses, it applies to a wooden frame without an air gap, and then EPS on which the render is applied.

If one were to be really picky, the facade and the load-bearing frame are separate parts of the building

Without moisture-sensitive materials, you don't have the same problems, even if the water still has nowhere to go. The best thing, of course, is to build a facade that actually keeps water out and directs it away.
