Thermal Performance
Condensation forms when warm, moist internal air meets a surface below its dew point. Glazing is usually the coldest surface in a conservatory.
Internal condensation appears because the room is humid and under-heated, not because the glazing has failed.
Glasgow's damp climate keeps external humidity high for much of the year, so unheated glazed rooms reach dew point most winter mornings.
Combine background ventilation, a steady low heat and improved glazing to stop conservatory condensation.
External condensation is not a problem, because it indicates the glazing is retaining heat inside the room.
