ᐅ New Construction with Sand-Lime Brick and External Thermal Insulation Composite System (ETICS) – Any Criticism?

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

Core insulation is not entirely free from doubts either...

There are several articles available online about this. The general consensus is that, if done correctly, it is a solid solution. With an external thermal insulation composite system (ETICS), there is certainly also plenty of room for mistakes in the execution.

I have exactly the same combination of sand-lime brick and external thermal insulation composite system (ETICS) and deliberately chose to install EPS insulation on my walls. I don’t understand the fuss.

The panels do exactly what they are supposed to do, which is to keep the heat in. I don’t care how the wall sounds… no one is constantly knocking on it, so where is the problem?

In appearance, it doesn’t look any different from a plastered 36cm (14 inch) Poroton, sand-lime brick, aerated concrete, or any other wall.

Whatever you choose—whether ETICS or thicker walls—it generally costs about the same and probably pays off after 30 to 50 years.

The indoor climate is the same everywhere since the rest of the house, according to current standards, is built up almost like a plastic bag. Unless you invest significant money and build with truly ecological materials, which only a few people do anyway… and then the question of using ETICS doesn’t even come up.

We have recently decided to go with an exterior insulation and finish system (EIFS). Each component of the wall does exactly what it is designed for, with no compromises.

Although we still have the choice, it will almost certainly be expanded polystyrene (EPS). It is affordable and performs its function very well. I don’t see any significant drawbacks. Fire safety is not an issue, indoor climate is fine (because the building is airtight anyway), disposal within my lifetime is irrelevant (and I strongly believe proper recycling options will be available soon), environmental concerns... sure, those can be raised, but please without double standards (flying across the ocean twice a year, driving an SUV in the city, daily meat consumption, yet having a problem with EPS... well, okay).

In my opinion, the only real disadvantage is that it is not that easy to attach things to the exterior wall later on. However, this is not a problem with proper planning.

That has always been possible... the myth of hazardous waste is just a misconception spread by opponents...

That also works very well because there are fastening systems designed for this... and usually, there is still a solid wall behind it.

By the way, a Poroton brick crumbles relatively quickly if you try to attach something to it.

And even if disposal costs 500 euros per ton, a single-family house weighs at most 2 tons.
