ᐅ Possible Thermal Bridges at Wall Corners in New Construction

Good evening,

Our new build is mostly complete, and the interior work is in full progress. The underfloor heating has been running for about 5 weeks.

We built with Wienerberger T10 36.5 without additional external wall insulation. Three of the four walls are below ground level, as our site is on a slope.

Where the brick wall meets the concrete wall, the internal temperature at the joint and corner is about 10°C (50°F) with an outside temperature of 1°C (34°F).

The other walls are around 15°C (59°F).

We took our first measurements today and will continue to monitor this daily.

What do you think—should we consider insulating the exterior facade after all?

In my view, this would clearly be a planning error, wouldn’t it?

Have you ever set up a dehumidifier on a construction site? Corners are always the last to dry out 😉

Yes, at the beginning when the base plaster was applied. For about 4 weeks.

But do you think the temperature is acceptable?

I think you cannot meaningfully measure temperatures in exterior corners during winter in a new building that is still a shell without exterior plaster.

It was probably not clearly stated; I measured from the inside. In other words, all the values in my first post are internal measurements.

Yes, understood.
