Experiences with Unipor W08 bricks?

Hello,

we have received offers from two general contractors for the construction of a KFW 55 house. Both GCs offer the Unipor W08 brick in 36.5 cm for the exterior masonry.

Do you have experience with these bricks or have used them yourselves in house construction? The GCs praise the brick in the highest terms....
Does anyone maybe have an idea how this brick is priced? (particularly inexpensive compared to a comparable one from Schlagmann or Wienerberger)?

Greetings from Schlagmann land :)

The basic idea of bricks with cream filling is not that new after all

Sorry, forgot to mention that it is about Unipor W08-PLAN and not CORISO.

For the builder, it actually doesn't matter whether the brick is from Wienerberger, Eder, Schlagmann, or Schlag mich Tod...

Sorry, I forgot to mention that it is about Unipor W08-PLAN and not about CORISO.

Even without cream filling, you cannot taste the manufacturer in the brick.
