It has been decided (by She Who Must Be Obeyed) that we need new fitted wardrobes. The current wardrobes were inherited from the previous owners and have a few worrying features:
1. The wall behind the wardrobe (an external west-facing flank wall) has been covered in polystyrene tiles. It also has a ventilation brick, possibly pre-dating the wardrobe.
2. The interior shelving has holes drilled into them, presumably for ventilation.
This all leads me to suspect there has been a condensation problem in the past. There has been no sign of condensation while we have owned the house.
When I rip out the old wardrobes should I take steps to insulate the rear wall before the new wardrobes are fitted? If so, what is the best method? Cavity wall insulation is not an option.
