Quote El Barbudo="El Barbudo"There may be advice out there but in my extensive trawls to find out whether my home [iis even suitable[/i for cavity wall insulation only leaves me with two opinions so far.
Opinion 1. You need cavity wall insulation, it's absolutely fine and we will come out and have a look, it'll cost you.
Opinion 2. Ooh no, your house is way too old and putting cavity wall insulation into such a house will actually make it damp as the cavities are an air-gap that keeps it dry.
I want to believe Opinion 1 and would be willing to pay for it to be done but Opinion 2 puts me off, I don't want to spend a small fortune on something that is going to ruin the place.
As the topic has arisen, I wonder if anyone can offer another opinion?
Built 1898, the house has cavity throughout between a stone outer wall and brick inner wall, has no "modern" wall ties but the walls are tied by some of the stones from the outer wall protruding-back-and-mortared-into the brick inner wall.
I have already insulated the attic (there is no loft) by putting Kingspan between the rafters and by insulating the dwarf walls and gable-ends with a similar product to Kingspan but with a plasterboard facing, attached by dab-and-stick.
It's well toasty up there and no sign of damp.
The house is also now part-double-glazed.'"
I have a similar type of property to yours, although about 30 years more modern. When our local council provided free insulation to all residents we were told (after the boroscope survey) our property was unsuitable for cavity wall insulation as, being rough stone outer wall (and having the stone "ties" as another obstruction) there was not a consistent cavity thickness for the insulation to flow and get an even cavity fill, which would lead to cold spots and possibly damp.
