I've been listening to the radio and have discovered that there is something called the Wind-driven Rain Index and that there are certain areas in the UK where this procedure should not be undertaken: needless to say the Companies that supply this stuff don't take much notice of that, relying on the fact that the customer will not be aware of such a thing and that the fact they are getting it for 'free' will sway them.
For those who have had this inappropriately installed the outcome is horrendous: within weeks their inside walls are streaming in damp, growing mould and becoming a very unhealthy environment in which to live. This is due to rain being driven into the outside wall and being absorbed by the insulation, so in effect it becomes a great big sponge. The householder has no redress and has to pay for the cost of removal, which can be up to £10,000.
If you are considering having this done (and you live close to the coast anywhere in the UK) please check this index - it may save you a few thousand pounds. DD
