I was a bit confused by StoneyBoy's advice to HilaryN (?) not to externally insulate her/his wall as it would stop the walls from breathing and traps moisture inside...
My question is: what are all those external insulation systems good for?
I am considering doing an external insulation, or maybe internally using Warm-a-wall, or Rubbercrete (google "walltransform.co.uk/products.php"
because our outside facing wall (non cavity) gets very cold in the winter, resulting in condensation and mould growth, please note that this only happens when the wall temperature is below a certain level, so it's not a damp problem.
What is the best solution for my problem??
Many thanks in advance
