In my contract with the construction company, I agreed to use the brick "Wienerberger 50-20 Plan" for the exterior walls of the house.
Now, the construction company has sent me the submission documents, but instead, the specification for the exterior walls states: "25cm (10 inches) timber frame masonry + ETICS (20cm (8 inches) EPS F-Plus + silicate plaster)," so apparently only 25cm (10 inches) brick plus insulation.
The construction company explains this as follows:
"For the exterior wall, a thickness of 25cm (10 inches) brick plus 20cm (8 inches) insulation was chosen due to better properties.
The U-value of a 50cm (20 inches) brick wall is 0.156 W/m²·K, and for a 25cm (10 inches) brick plus 20cm (8 inches) insulation wall it is 0.138 W/m²·K.
With a 25+20 exterior wall, sealing is much better, there are fewer thermal bridges, and there are no problems with installing roller shutters."
I am now uncertain – should I insist on the original version or choose the new one?
Additional info: The house is single-story, just under 8 meters (26 feet) high, and since it will mostly be used in summer, it is more important to me that it does not heat up quickly and strongly, rather than cooling down fast. Sound insulation is less important, as the neighbors are far away.
Thanks in advance for your answers!

Hello,
even if I completely confuse you with this: then you are mistaken with the Wienerberger Porcelain. Mass is what helps you. Calcium silicate walls, preferably 24cm (9.5 inches), and then 20cm (8 inches) insulation. That’s the finished cabin.
Best regards,
Andreas

What on earth is a TIMBER frame MASONRY supposed to be?
