Hello,
we are currently deciding on a construction company. Our main question right now is how we should build our house. We have one offer with a 36.5 cm (14 inch) aerated concrete wall with plaster, and another offer with a 17.5 cm (7 inch) aerated concrete wall plus 14 cm (5.5 inch) external thermal insulation composite system (ETICS) using mineral textured plaster as the top coat with a 2 mm (0.08 inch) grain size, and a base plaster with colored stone plaster as the top coat.
We are very inexperienced with building and do not know which option is better. The house will be built in a quiet village with no traffic noise. It is important for us that we do not have high heating costs, but that the walls can breathe and there is no risk of mold growth.
We appreciate any tips and advice.
The heating system in offer 1 would be gas plus solar, while offer 2 includes an air-to-water heat pump.
Best regards

This has less to do with external thermal insulation composite systems (ETICS) than with the high airtightness of modern buildings.And thermal bridges. A point for ETICS. *getting popcorn*
Mixing with aerated concrete, however, seems odd to me. Either make a purely monolithic wall or use ETICS with the corresponding sand-lime brick. Both will result in a house that offers comfortable living.
Comfort comes before saving. They are forcing us into insulation madness. Energy saving regulations or no building permit. But they can’t force us to behave like everything has to be insulated. We were just in Italy. Do you know what kind of windows they have there! We are completely over the top here. Karsten
I wanted to tell you that airtightness is not the issue. Aerated concrete with plaster on both sides is also airtight, as is the EIFS (External Insulation and Finish System) facade. So, that’s not an argument for or against. If later on you want to metaphorically chisel holes back in, that’s up to you. But it’s not necessary; some things simply continue to develop.

Isn’t that a contradiction? An insulated wall and then basically permanently open windows? The first one then doesn’t really make much sense anymore...Contradiction is part of politics.

Stupid software. I was responding to bluminger, not you, Alex. They often offer this as an alternative here in the north: thin aerated concrete plus external thermal insulation composite system (ETICS) or thick without. It seems to be similarly expensive to produce.
And yes, the troublesome thermal bridge issue used to be much less of a problem due to less airtightness. An old, completely unheated fieldstone church from the 14th century is not airtight at all and usually has no mold. Karsten

Not directed at you, Alex.No worries.
