Which option is the "better" one, or is there really a noticeable difference in terms of sound insulation?
17.5 cm (7 inches) planer brick T1.0 with 20 cm (8 inches) ETICS (External Thermal Insulation Composite System) or
17.5 cm (7 inches) calcium silicate brick with 20 cm (8 inches) ETICS?
The single-family house (1.5 floors) is planned to meet KfW 70 standards, about 150 sq meters (1,615 sq feet) with triple glazing, etc. It is actually a quiet residential area on a dead-end street (a four-lane road about 1 km (0.6 miles) away, which you only hear as a background noise).
Although calcium silicate bricks are said to have better sound insulation, would I as the homeowner actually notice it (considering windows and roller shutter boxes), or is it just "theoretical"? I have gotten a bit unsettled by posts saying that the planer bricks are so thin-sounding that you can hear conversations through the exterior wall. Or am I just creating a "luxury problem" because I want to build anyway in a quiet neighborhood and usually don’t hear much from the neighbors? Or does more noise come through the windows and shutter boxes than through the walls?
I know it’s hard to judge such things from a distance and everyone perceives it differently, but I have some concerns about sound going in and out with the brick option—it just seems a bit thin, especially if sockets and such need to be installed in the wall… (but that will be calculated/regulated by the structural engineer). Also, it makes me a bit suspicious that the manufacturer recommends this planer brick only "for load-bearing and non-load-bearing interior walls without special requirements for sound insulation," and now it is supposed to be used as an exterior wall with ETICS.
Both suppliers are similarly priced, but I would somehow prefer the bricklayer since he is from the neighboring village and the other is 100 km (62 miles) away.
Thank you very much for your advice/tips.

Hello,
There is indeed a difference. However, if you live in a quiet area and don’t have high demands, you won’t likely encounter major issues with brick. You should also consider sound insulation within the house.
Personally, I always prefer sand-lime brick. Its advantages lie in soundproofing, structural stability, and summer heat insulation.

Achieving KfW 55 standard is definitely possible without much additional effort!
If you are close to that, it’s definitely worth considering. Better funding conditions + 2,500 €.
Best regards
