Temporary condensation within windows.

[BobT_5041460]

Had to go to my dealer today after discovering condensation within my windows.

According to him they have had quite a number of complaints re this problem.

I was handed the following sheet which may help anyone else with this problem.

Why it can occur?

At this time of year we receive several calls & letters regarding condensation forming within the glazing on some caravan windows. The drastic changes of temperature & the moisture in the air both contribute towards the temporary condensation, that disappears as quickly as it appears. The whole phenomenon is purely related to ambient temperature 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 susceptable to temporary condensation if the temperature difference between inside & outside changes quickly and/or dramatically i.e. if a cold caravan is heated quickly using the heater or by the sun. This can be exaggerated particularly so if the ventilation within the caravan is not sufficiant; bedding or possessions can sometime block factory fitted vents for example.

How to overcome it?

Condensation can occur when the humidity inside the caravan exceeds 60% & ventilation is insufficiant. To overcome this, please consider the following:-

* Improve ventilation

a) Leave rooflight open.

b) Add to the ventilation by fitting more improved ventilators.

c) Leave doors open between compartments.

d) Ensure that factory firred ventilation a

is not obstructed.

* Self help tips

a) Do not wash crockery last thing at night, it creates moisture in the air.

b) Do not boil water last thing at night & empty all water from kettles etc.

c) Remove flowers or vases containing water from sleeping quarters.

d) Keep temperature to a minimum (hot air contains water vapour).

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

Or in other words they don`t know how to solve the problem.

Caravan double glazing isn't filled with a vacuum or clinically dry air, so the condensation IS perfectly normal and more noticeable if you caravan all year round, because of the temperature difference between inside and outside.

Ignore it, just enjoy your caravanning.

Perfect timing,

I noticed this for the first time on the front windows this weekend. The explanation sounds about right, Saturday a really nice day, quite warm and then a cold frosty night. Result condensation in the front windows.

Thanks guys I now won't fret about it !!!!!!!!!!

You've saved me a phone call to the dealer. Had the same phenomenon weekend before last, cold night, very warm day. global warming I suppose. Thanks.

The condensation issue has been around for a very long time.

Most windows have two small bungs, usually at the top left and right corner area which can be removed to allow the moisture to vent out if removed when the weather is warm and dry, and replaced before the sun goes off the windows to stop the inner air cooling and draw in more moist air.
