I am thinking of having cavity wall insulation injected into my house
cavity. Are there any negative points in having it done? Are there
different types and which is the best? The part of the house in question is
about 40 years old, the new extension part is already insulated.
Thanks for any comments.

I had cavity wall insulation installed at the same time my new boiler was
put in back in April, which was a bit of a mistake, due to the fact he was
still sorting out the new flue at the time - so all the new insualtion blew
out all over the place.

I think they all pretty much use the same material now-a-days, which is sort
of like a feathery, cotton wool kind of thing.

We had it done about 7 years ago...

No problems noted and the house does seem to retain its heat for
longer.

Mine was done 10 or 15 years ago (previous owners) and doesn't seem that
great - it doesn't extend above the ground floor all round the house.

Also when I got the govt sponsored bods along to assess the options of
grant assisted loft insulation (none!) they observed that they would not
top up any existing cavity wall insulation, not because of unknown
provenance (same big UK firm whose name I forget installed it originally
as came to do the loft inspection) but because they do not add to
existing installations, and he said no one else would.

FWIW

Fuel bills?

Doctor Drivel explained on 06/08/2005 :
Fuel bills?

Difficult to work out just doing what made what difference. It was part
of a program of improvements. The impression was that the outside walls
became quite a bit warmer in winter and in summer it remains cooler.

The combined result of all of the changes has been a very noticeable
improvement in reducing fuel used, but more important the biggest
difference has been in comfort levels with no cold spots anywhere in
the house.

Same here. Both loft and cavity insulation was done early this year. The
loft was an added to, added to insulation and is now about 8 inches, or
more thick.

When the cavity insulation was done and I took a temperature reading of
the outside wall in our kitchen and compared it with an interior one on
the day of the insulation, there was a 9 degree C difference. These
days, even in the cold late winter, my one luxury in life, my half pound
of butter a month, spread easily. In the cold old days I would have to
chip it off the block and place it on the bread :-)

As you say, the comfort level has improved very noticeably.

Fuel consumption will have to be checked after the insulation has been
in place for at least a year.

What are the initial results? You must have had your first bill by now.
