Hello,
I am planning to build a KfW55 solid masonry house and am currently unsure which bricks are truly suitable.
The company specified:
Exterior wall:
36.5 cm (14.4 inches) porous smooth-planed perforated brick with tongue-and-groove edges, laid with thin-bed mortar.
The requirements for an energy-saving regulation house are met without additional insulation.
UNIPOR W07 U-value 0.18
There are really very different opinions regarding bricks.
I would like to hear your thoughts on this.
I will also receive other offers and can gladly add the suggested bricks later.

Purely for energy saving reasons, he always says that with the 42cm (16.5 inches) wall, the U-value is about 25% better and the additional cost would have been worth it. Whether that is true is something everyone has to decide for themselves.With roughly 13% more wall thickness, meaning about 25% better U-value with the same brick... It should be obvious that this statement is quite nonsense 😉
