ok I see - so I need something completely non porous to stop condensation forming in the first place. But then if you have a complete blocking layer wouldn't you get dampness from sweat which can't evaporate??
Sooz, we're stealing the thread, but I'll still answer this one. The dampness which will collect in your bed clothes and in your bed will not "circulate" to cause condensation which is the "circulation" and contact with "Cold" objects. You can get condensation on your tent roof just the same as under the mattress when the warm moist air "circulates" in contact with a cold tent surface and then condensates and drips from the material. Again, if you break the contact between the cold and warm moist with an insulating layer ie. bubble wrap or space blanket type of insulation, the condensation doesn't have a chance to form and either absorbe into your bed or drip from your tenting.
I asked about condensation last year thru a thread on UKCS. and got mostly negative replies. I can get a space blanket to fit most needs, either under the bed or on the tenting, whichever, to end the troubles with condensation. I only need to know if people would want it so I can order enough to make it worth all our wiles. The material is expensive in small batches, and pre cut fit material for beds and tents a little more expensive, but if I order enough in various sizes (limiting the different sizes to a maximum of 3 for tents and 4 for beds, I could get them relitivly cheap (We're talking about 40Pounds for the tent and 15 or so for each bed. (These are park prices, real general estimates on the costs, without postage etc.)
This is the same type of material I use on my camper, and I've camped in 0°C weather with 4 people in my camper and NO Condensation on the bed, roof or tenting.
Rain today, maybe no snow next week, 3 weeks to go until Easter, my plans for camping are starting to look good!!.

Hello, not sure if this helps but like Robert who posted earlier, we were advised to put a layer of newspaper (1-2 sheets thick) under the bed each night to absorb any damp. In the morning we throw it out and turn the mattress over or prop it up to air. This seems to work fine for us and it's very cheap!
Sud-
The layers of newspaper absorb the wet, but the hassle is the cleanup and throw away. If I stuffed newsprint under my mattress and let it get wet, eventually I'd be able to read my paper by flipping the mattress..... Also, here in Germany, everything has to be separated at the dustbin, another hassle, and who carries so much newpaper just to "lay under the mattress", especially if you're gone for several weeks.

We are going to put down some special laminate underlay, its got a silver backing and spongy corogated foam stile topping only 2-3mls thick. and its warm to the touch.
