Hello ABG claimant,
have the engaged experts ever examined the water vapor diffusion for the exterior wall construction installed there and conducted a dew point calculation?
If possible, an exterior wall construction should become increasingly vapor-permeable from the inside to the outside. However, it seems that polystyrene insulation boards have been glued directly onto the chipboard panels. This creates the risk that condensation will occur on the back of the insulation boards, which also do not seem to be very thick (perhaps 4 or 6 cm?). This assumes that moisture from inside or also moisture from outside penetrates into the construction. This then leads to rot and mold formation over time.
Since such a structural defect cannot be recognized by a house buyer, I would classify this as a so-called "hidden defect" in the truest sense of the word. To my knowledge, the manufacturer is liable for such defects far beyond the usual warranty period.
If all else fails, I would also consider filing a criminal complaint for bodily injury (health damage due to mold infestation). In this case, the public prosecutor would investigate; this does not incur attorney fees but substantially hardens the fronts.
Kind regards
