Hello everyone,

I’m new here and have already browsed the forum a bit for my question, but haven’t found anything quite suitable so far.

We are in the final stages of working with our construction company, and one of the bigger topics for us is the wall construction.
We definitely want a brick or brick slip finish – but because of the quality, we are leaning towards real bricks.

Using a T8 block (36.5cm (14.4 inches)) with brick, the wall thickness ends up just under 50cm (20 inches).
We are a bit unsure whether that might be too thick and possibly look odd. Does anyone have experience with this?
And what are your experiences regarding the indoor climate with this kind of wall construction?

We have now received an offer from the general contractor for the KFW55 wall structure with the following setup:
240mm Poroton (T8-filled), 120mm mineral facade insulation, 10mm air gap, 115mm facing bricks

I’m surprised that the Poroton block still needs to be filled – what are your thoughts on this?

The filled Poroton brick slightly improves thermal insulation, but in my opinion, it is more important for reducing sound transmission between floors and to the outside.

240mm (9.5 inches) Poroton (T8-filled), 120mm (4.7 inches) mineral-based exterior insulation, 10mm (0.4 inches) air gap, 115mm (4.5 inches) facing brick
[...] – what do you think about this?

I would say that this is equivalent to the originally proposed build-up: neither noticeably better nor worse, just different.

The fact that mineral wool alone does not directly replace the same thickness of porous bricks 1:1 does not surprise me.
