A couple of years after the introduction of styrofoam ceiling tiles on sale, it could be seen in every second apartment. It seems to be “out of fashion” now, but, in my humble opinion, there is no more economical and easy-to-install finishing material for the ceiling. I have always preferred natural materials: natural wood clapboard to vinyl siding, wooden parquet to laminate, and I used only plaster for the ceiling decor. However, when repairing the bathroom, it turned out differently.
What happened before the renovation
Previously, the ceiling was covered with whitewash, which lasted for many years until there was a water leak from the neighbors above. As a result, yellow spots appeared even through putty and whitewash. Attempts to remove this defect did not lead to anything.
The suspended structure would avoid such problems in the future. I have already had experience with its device made of 50 × 50 cm plastic tiles and a rack-and-pinion profile, in which small halogen lamps are usually installed. And I was already inclined to do something similar.
