| Hi,
We don't get any as we use the external silver screens, also its worth noting that there were suggestions a few years ago that if you allow condensation to accumulate on the front window it can drain down behind the dash and start to rust the bulkhead metal.
As I said at the start we used to get it a lot until we changed from internal screens/curtains to outside sliver screens which virchally stop it completely | |

| Thanks for that... never thought of external screens.
I've got some internal ones... but always dripping wet in the mornings. | |

We use the crystals in the front and they do the job without taking any valuable space up, unfortunately unless you keep the cockpit area well ventilated you will never completely get rid of it | |

| Hi,
To try to explain the reasons as simply as possible, if you can imagine that as you breath out you expel an amount of water, and this is held as a vapour in the relatively warm air that surrounds it, and as the air floats about staying warm there is no problem.
However if that air, that is relatively warm starts to get cold the water vapour turns to real water, which we see and call condensation, as you know when you wipe it up its real water.
So what can you do ? keep the air warm and keep it moving ? easy isn't it, so lots of heat and plenty of ventilation, problem solved.
Now the real world, obviously the above is correct no question, but can we afford to leave the windows open and the heating on, I doubt it, so what else can we do to try and mitigate the situation.
In normal practice the main areas that we find the problem is when that warm moist air with the water vapour in it hits a cold surface, that can be a window , wall and will be noticed as good old condensation e.g. wet even running water.
However another more sinister problem is the Black mold growth which is normally found under the mattress, back of cupboards, back of Wardrobes again caused by the good old condensation.
All of the above will and do form anywhere that is colder than the air itself, and all of the places I have listed and some that I haven't need checking, as while the windows are the obvious problem in this thread the others are perhaps more serious and can lead to breathing problems
Now what can be done, as stated above heat and ventilation is so important and must be the priority ,
However the relatively simple solution for the window situation is to keep the window GLASS as warm as possible and that can only be done externally, you cannot keep the GLASS warm by hiding if from the condensation e.g. putting a cover/curtain etc over it, the warm moist air with the water vapour will just pass through or around those objects and then condensate out on the cold GLASS
The mold growth in the cupboards wardrobes under the mattress they need ventilation e.g. get the mattress up off the flat board to get some air movement under it. make sure the items in the cupboards cloths etc have enough space around them for the movement of air, and make sure any air vents in the van are clear and clean.
If you have a extract fan run it when ever you are boiling/heating water having a shower etc. if you don't have a fan and you are having a shower washing etc keep the door closed on the room compartment your in and when you can open the window to expel the steam moist air, as any moisture from washing etc will stay in the van unless you ventilate it
Hope that helps

| I also use an external silver screen but nothing on the side windows as they are double glazed, when I do not put the screen on the condensation is horrendous and with such a large dashboard is hell too dry up. | |

The only way you can help to keep the GLASS warmer, other than by applying heat, is to protect it directly from the cold itself and the only way to do that is to cover it EXTERNALLY with insulation and that is exactly what the Silver screens or Taylor made covers do.
The mold growth in the cupboards wardrobes under the mattress they need ventilation e.g. get the mattress up off the flat board to get some air movement under it. make sure the items in the cupboards cloths etc have enough space around them for the movement of air, and make sure any air vents in the van are clear and clean. Suggestions for the Mattress are fit the bed slats from the likes of IKEA under the mattress or I have heard a good layer of bubble wrap may also help, I'm sure there are other suggestions, as for the cupboards/wardrobes I haven't any really firm suggestions other than to make sure there is a clear air flow and you check and clean it regular if you do see any signs of mold with a mold killer
The warm moist air doesn't just come from you breathing it comes from any use of water in the van especially if you have or use it warm or hot e.g. washing of all types, my suggestion recommendation is, If you have a extract fan run it when ever you are boiling/heating water having a shower etc. if you don't have a fan and you are having a shower washing etc keep the door closed on the room compartment your in and when you can, open the window to expel the steam moist air, as any moisture from washing etc will stay in the van unless you ventilate it, its worth trying to give the van an airing during the day as that moist air will linger around for a long time if possible albeit during the winter that's easier said than done ?
Hope that helps

| External screens for me too, keeps the condensation off the cab windows. I always have about half a dozen of the traps in the van when in storage, keep all cupboard doors open and its surprising how much water they take out. _________________ Keeping Leapys boat sailing [You must be registered and logged in to see this image.] | |

| Hi again there is no problem with keeping those damp traps in the vehicle all the time espcially in the hidden areas where damp and mold may be found e.g. bottom under draws etc. the only problem is I have heard some people can be allegic to them so double check I personally get a funny taste in my mouth if i get to close i.e. touch them NOT LICKING THEM LoL | |
