Hello forum,
in our conservatory there has been a clearly noticeable odor nuisance since completion (a little over 1 year). Since it was so intense last spring that use was not possible, we had an indoor air check carried out. The result was that
1. VOC/solvents were detected at a concentration of 900 μg/m3,
2. plasticizers/phthalates DEP 20 μg/m3 and DIBP 4 μg/m3 were detected.
The values for solvents are clearly in the perceptible range (according to AGÖF), DEP is well above the orientation value (according to AGÖF 1.8 μg/m3) and DIBP should have actually been banned since 2015 according to REACH.
The general contractor responsible both for the house and the conservatory doubts the measurement and demands that we test the installed materials and not the air, i.e. take samples from all construction materials present in the conservatory by scraping, cutting, drilling and send them for analysis.
Since we want to avoid these visible damages in the conservatory as much as possible, my question is in which building materials the aforementioned solvents and plasticizers could be contained. Especially since after long searching on the internet similar defects do not seem to be common, I suspect that it is rather not the conservatory construction itself (aluminum, paint, seals) that are the cause.
The following is known to us from the construction phase:
1. The conservatory was attached to the external plaster of the house
2. The exterior paint had already been applied
2. In contrast to the rest of the house quick screed was used, which was dried under massive use of the underfloor heating before the tiles were laid.
I would like to thank you in advance for ideas and suggestions!
