I am hoping to get external wall insulation. I can't get the foam, I have cavity blocks as opposed to cavity wall. So I have had someone out to look over the house. Semi D built 1960ish and bloody freezing!!
What thickness should the polysterene Panels be???
He says they put aluminium on the bottom and a different polysterene (like what is in a swimming board and it's waterproof). Does this sound right?? I probably have left our huge bits in what he said but you hopefully get the idea.
Finally, my satelite dish. Can it be put back on over the polysterene or should I leave it and let them work around it????
Any ideas of a ball park figure for a small 3 bed semi d in Dublin for this type of insulation??? Just a vague idea.
Any idea how much I would save on heating by doing this?
Any other pointers?
