Can anyone give any advise as to why a laminate floor inside a conservatory is showing signs of condensation. The conservatory is edwardian, in UPVC with glass and panels below a midrail at approx 600mm. The condensation shows more or less nighty from the edge to approx 300mm in on three sides (Not house wall side). There is a DPM below the concrete base. The floor has been screeded and apparently there is underlay beneath the floor. There is heating and ventilation in the conservatory.
