Hello,
the insulation beneath the exterior window sill made of natural stone is only 1cm (0.4 inches) in our case. The exterior window sill itself is 3cm (1.2 inches) thick. What do you think about this? Is this in accordance with DIN 4108-2?
My assessor says this is far too little for thermal conductivity class 035. The general contractor does not acknowledge the issue and wants to charge me for any potential additional costs.
The construction is using T9 stone with 36.5cm (14.4 inches) masonry.

Is this a window with a “standard” sill height?
I am only familiar with insulation of this reveal for floor-to-ceiling windows on the ground floor. But maybe it isn’t insulated in our case because we built with a T6.5 brick, which already has a better thermal value. I am currently insulating the floor-to-ceiling windows myself (with 8cm (3 inches) XPS).
