Window Condensation

Condensation in the Caravan Windows

Why it can occur?

At this time of year we receive serveral calls and letters of query regarding condensation forming within the glazing on some caravan windows. The drastic changes of temperature and the moisture in the air booth contribute towards the temporary condensation that disappears as quickly as it appears. The whole phenomenon is purely related to ambient temperature changes of caravan versus window cavities.

It is a popular misconception that acrylic caravan windows are vacuum sealed. This is not so. The windows in a caravan can, as with domestic glazing, be susceptible to temporary condenstaion if the temperature difference between inside and outside changes quickly and/or dramatically I.e if a cold caravan is heated quickly using the heater heater or by the sun. This can be exaggerated particularly so if the ventilation within the caravan is not sufficient; bedding or possessions can sometimes block factory fitted vents for example.

How to overcome it?

condensation can occur when the humidity inside the caravan exceeds 60% and ventilation is insufficient- to overcome this be consider the following-

• Improve ventilation 

1. Ensure that factory fitted ventilation is not obstructed.
2. Leave doors open between compartment.
3. Put windows onto night-vent position.
4. Add to the ventilation by fitting more improved ventilators.
5. Leave roof light open.

• Self-hip Tips 

1. Do not wash crockery last thing at night, it creates moisture in the air.
2. Do not boil water last thing at night and empty all water from: kettles etc.
3. Remove flowers or vases containing water from sleeping quarters.
4. Keep temperature at night to a minimum (hot air contains water vapour)
5. Increase ventilation to above normal in inclement or very wet weather.

N.B you cannot expect to eliminate condensation completely but following the hints above will help towards a more comfortable environment.
