I was thinking of putting some of that 2mm polystyrene roll on the outside
walls before I wallpaper.

Has anyone ever used this before? Does it actually stop condensation? I
have a condensation problem in winter, behind wardrobes, drawers, pictures
etc.

The real answer is to increase ventilation, most older houses now have all
the natural ventilation of draughty windows and doors sealed up and their
chimneys blocked, the lofts insulated and sealed off.

Put in some air bricks, put auto extractor fans in kitchens and bathrooms
and all the problems will disappear.

You will probably be very disappointed with thin polystyrene under the
paper.
