Possible thermal bridges in house wall corners in new construction

Good evening,

Our new building is underway and the interior work is in full swing. The underfloor heating has been running for about 5 weeks.

We built with Winnerberger t 10 36.5 without additional facade insulation. 3 of the 4 walls are underground because we have a hillside location.

Where the brick wall meets the concrete wall, the indoor temperature at the corner is about 10 °C (outside temperature 1 °C).

The remaining walls are about 15 °C.

We measured for the first time today. I will do this daily now.

What do you think, do we possibly need to insulate the exterior facade after all?

From my point of view, that would be a clear planning error, wouldn’t it?

Ever set up a construction dryer before? Corners dry last ;)

Yes, at the beginning when the basic cleaning was done. For about 4 weeks. But do you think the temperatures are OK?

I think you cannot meaningfully measure temperatures in exterior corners in winter in the new building as a shell with missing exterior plaster.

Probably not clearly worded, I measured from the inside. In other words, the values from my first post are all from the inside.

Yes, understood already.
