Hello Forum,
We are planning a new building using calcium silicate blocks plus an external thermal insulation composite system (ETICS).
I’m sure many of you are familiar with the critical videos about ETICS on YouTube. Yesterday, I watched this one:

High-level experts and former employees of ETICS companies confirm the issues within the industry here.
This perspective can unsettle a layperson. However, in my opinion, the research and analysis were thorough.
I understand that ETICS has been around for many years. In all these videos, it’s only criticized.
But no one explains how to build properly in this context.
In your opinion, is there some truth to this? Or is ETICS just highly rated because of lobbying?
Regards,
Confused layperson

As I mentioned earlier, I deliberately had it attached directly to the house because it performs its function very well and is not hazardous waste, but a completely normal building material... which, unlike many other supposedly eco-friendly materials, can be recycled very effectively.
However, this is not necessarily required, because if installed properly, it will stay in place at least until the plaster is removed.
You believe it is the worst thing you can do... but why?
It is not hazardous waste – the packaging for your TV is made from the same EPS and goes into the recycling bin, and this has been standard practice for decades... yet suddenly people claim it’s hazardous waste just because it is applied to exterior walls? Don’t you see something is off there?

I don’t think the foam used in TV packaging is exactly the same EPS overall. In insulation materials, there are certainly many additives, for example for fire resistance and other purposes. While I don’t believe it’s as extremely harmful as some here suggest, it’s not completely harmless either. Maybe a bit more objectivity?

As I am a known opponent of ETICS (external thermal insulation composite systems) and want to avoid any bias, I recommend taking a look at the new study by the Fraunhofer Institute in cooperation with FIW Munich. It states, among other things: **"If dismantling cannot be avoided, according to the authors, energy recovery will be the method of choice over the next decades. This is because the expected hazardous classification of the flame retardant HBCD used will significantly limit recycling options.
Therefore, the study recommends that the industry focus strongly on developing new fastening technology for easier dismantling in the future and technically advance the issue of additional insulation layers."**
It will therefore take several more years until EPS is fully recyclable; which necessarily requires new types of insulation materials of this kind to be developed. The current problem is rather the durability of the material and thus the question of disposing of first-generation insulation boards. So the argument of "hazardous waste" cannot be dismissed so easily.

No one doubts that HBCD is present, yet EPS and Styrofoam are treated the same way in the same facilities...
But HBCD is also used as a flame retardant in sofas, textiles, and electrical appliances... does that mean all of that is hazardous waste now?
Isn’t there a double standard being applied here?

But that is not absolutely necessary, because if installed correctly, it will remain in place at least until the render is removed.In my opinion, EIFS (external insulation and finishing system) fails entirely at one important function: creating a proper exterior surface for the building. It is neither hard nor durable, does not withstand accidental impacts or certain animals (woodpeckers...), nor long-term weather exposure. A solid, monolithic construction is better for that. Especially a cavity wall system. That’s why I believe EIFS is the worst choice you can make.
On the other hand, I do agree with you: it works, so it’s not really “bad,” but in my view, the alternatives are better. Also, I hardly believe that many homeowners prioritize an eco-friendly conscience so much that the recyclability of the insulation has a major influence on their decision.
