ᐅ Exterior Wall for KfW 40 (+) Standard: With or Without External Thermal Insulation Composite System (ETICS)?

Monolithic simply means continuous, so every completed wall is monolithic or composite.
The only question is which insulation material is used and where it is located.
Everything else is marketing.
Nowadays, thermal bridges are what really matter. Often, the equivalent proof is missing or not provided at all.
The question often is whether calculations are still based on the old DIN standard or the new DIN standard.

Ecological and economic considerations are, independent of this, the responsibility of the builder.

Weren’t you of a different opinion here? 😉
Sure... that was in 2018. May I ask why you are now in favor of filled bricks? Did you have negative experiences with the unfilled ones?

That’s what you call experience-based. I have a 365mm (14.4 inches) T8 unfilled brick myself and we don’t have any problems with noise from outside. We also don’t feel cold in the bathroom at 20.5°C (69°F). Others feel like it’s “The Day After Tomorrow” at that temperature.

In other words, everyone perceives it differently. It’s just like tastes.

But I don’t like external thermal insulation composite systems (ETICS). I had it in my last apartment. It’s not my preferred building material.

And here I would also appreciate an explanation.
What problems or negative experiences did you have?

What is so bad about the expanded polystyrene? You can still thermally recycle the external thermal insulation composite system (ETICS) after it has protected the climate through its insulation effect for 50 years. That’s quite an impressive environmental balance. The concrete block houses with gas condensing boilers are the bigger climate offenders and even worthy of a local Fridays for Future protest.

Expanded polystyrene is waste that, in the end, can only be incinerated because it is no longer useful for anything else. Whether it actually lasts 50 years is another question. Monolithic masonry lasts until demolition.
And the building envelope is completely independent of the heating system 😉

I believe that nowadays—besides the necessary energy saving regulations/planning permission requirements—there is often an excessive concern or uncertainty about whether one wall construction is better than another.

I lived for 30 years in a completely normal house built with Poroton blocks, and I never felt cold in the bathroom nor did noise ever give me headaches. Almost every house in that neighborhood was built like that back then, and they are all still standing. This usually depends on other, especially very individual factors such as personal perception, the location of the house/rooms, behavior/education of children/spouses... 🤨 🤨 etc., which I totally understand.

I actually think that nowadays there is often more noise inside the house than what comes from outside; the noise inside just goes unnoticed because it is constant and perceived as “normal.”

Our house was supposed to be built with Liaplan blocks, but since another shell construction contractor is now in charge and the structural engineer, for whatever reason, calculated everything using bricks, that is what will be used. I often and gladly think about it, but not right now.

I would do that if I really had specific requirements like a busy street or similar noise issues.

Maybe a bit more nuanced.

No, I’m not going to write an expert opinion here. If you want opinions, you’ve got mine.
I’m done with ETICS! Plastic, soft, environmentally unfriendly—that’s enough for ME not to use it anymore. If you want approval here, you won’t get it from me.

How many nails have you driven into your facade so far...?

That’s the point: total inflexibility for creative people!

With ETICS you simply have a top insulated exterior with state-of-the-art U-values.

Yes, well… top, but no quality. It reduces the quality of the house!
