Generally little danger, because the external insulation layer mostly provides so-called negative thermal bridges at external corners and does not involve any danger for intersecting construction elements on the inside. However, thermal bridges can occur at penetrations of the insulation layer to the outside (e.g. for anchors).

The proportion of timber in the structure (because of its higher thermal conductivity as compared to the insulation material), and critical areas such as the dado, intersecting ceilings and inner walls and the junction with the roof.

At construction elements with deviating coefficients of thermal conductivity, if they intersect the external wall.
