Preventing condensation
11 Answers
Part of my bedroom wall forms the entrance porch resulting in an exterior wall being single course and north facing. Consequently, condensation forms in the bedroom on this part of the wall. Is there any way of preventing the condensation from forming.

The latter is possibly easier to achieve if somewhat more expensive. You could vertically batten the wall, put say 30mm of Celotex/Kingspan rigid foam installation between the battens, plasterboard over then redecorate that wall. Would scarcely know it was there.

'Thin foamy stuff'' equals Celotex or Kingspan, which is sandwiched between outer layers of silver foil. This is the commercial product - but I suppose you can make our own if money is tight and your labour is free.
You have to combine some 'thin foamy stuff' with a layer of silver foil. Notwithstanding the above response from Bravejordy that says it worked for him, silver foil on its own merely reflects heat back into the room; condensation is caused by water vapour in warm moist air touching a cold surface; the water vapour then turns to water droplets. Silver foil on its own without insulation on the other side of it is still cold - so water still condesnes onto it.
