Hello experts,
I received an offer from a company for the following masonry: 17.5cm (7 inches) Poroton block plus 16cm (6 inches) external thermal insulation composite system (ETICS). However, I am more inclined towards a monolithic construction and communicated this to the company. Now I received an offer for a monolithic construction made of aerated concrete (Ytong) with a thickness of 36.5cm (14 inches). The additional cost for this is 8000 €.
What do you think?

Hello,
Personally, I would lean towards the 36.5cm (14 inches) Poroton brick.
The disadvantages of the ETICS (External Thermal Insulation Composite System) are, in my opinion, quite significant.
These include:
- Risk of moisture damage if the installation is not done properly
- Woodpeckers have discovered ETICS as a perfect nesting site, leading to increased costs for repairs
- Fire safety! Although ETICS systems are supposed to be fire-retardant, tests and unfortunately real fires have shown that this is not always the case, and fire can spread up the entire exterior wall
- The appearance after a few years: once the fungicides and pesticides wash out, algae and similar growths can settle freely. (However, this might also be an issue related to the render or exterior coating and can potentially occur with 37.5cm (15 inches) Poroton as well)
I once found a good report on YouTube from NDR; just search for
"45min thermal insulation systems"
Best regards

Algae growth mainly depends on whether the surface can dry quickly enough or doesn’t get wet at all (roof overhangs). The distance to forests and shrubs also plays a role.
This entire report from NDR is pure scaremongering. It has already been thoroughly discussed.

If necessary, burn it completely. Yes, it’s really not that difficult.
