Nikoftime: Would you buy a house with polystyrene cladding?
Timber frame, wrap, cavity, polystyrene and then plaster.
Is it the general perception that this is potentially leaky and if yes, why would it be more prone to leaks than any other form of cladding?
Even if the house were 100% OK, i'd still be hesitant. If you go to some open homes, you'll see double or triple the number of potential buyers looking at timber weatherboard or brick homes than you see at plaster homes these days. Lower demand must equal lower prices and longer time to sell.
