ᐅ Thermal Bridge Repair in New Construction

Hello everyone,

Since quite a few things have gone wrong with our new build, I am seeking advice and information regarding the installation of insulation and waterproofing.

After a thermal bridge was detected at an exterior corner, insulation boards were attached on the outside to fix this issue. In my opinion, the work was not done professionally because the boards and plaster protrude by 3-4mm (1/8–3/16 inch) and the facade is not flush.
Please see the attached photos. By the way, the building is less than six months old and still under warranty.

My question is: Is such a repair method even appropriate for a new construction? Shouldn’t the facade be opened up to address the thermal bridge directly within the wall?

If this type of repair is acceptable, I would like to know if there are any tolerances when insulating with external insulation boards. Visually, it just looks terrible.

Regards

Well, even if it is technically correct, which I personally cannot assess, both facades should have been completely replastered so that these transitions are no longer visible...

Not necessarily completely new now, but plastered in a way that it would no longer be visible.

What did they do there? Did they glue an insulation board underneath? A thermal bridge is not really repaired but sealed by continuous insulation. However, it is not possible to tell from this whether that has been achieved here.

Yes, exactly, insulation boards were installed and then plastered over. Since then, the thermal bridge has not been visible.

I have an appointment with the client today, so let’s see what comes out of it.
