32-floor building, condensation and ceiling damage by dropping water in the corridor. Maintenance contractor did a job for 10 floors that there was two shaft, sealed from the top with the aluminum bond sheet and treated with existing fresh air.(pressurized).then the only damaged insulation was replaced by form insulation(in affected areas) And sealed maximum visible holes on walls. Existing is fiberglass insulation. Yesterday I rechecked the site found again condensation stated on insulation, drops water on existing insulation. I took the temperature by laser thermometer on insulation, existing fiberglass surface temp=25C and new form insulation surface temperature =20c.
SPACE condition now =DB/WB 24c/18C.
