Hello,
We live in an end terrace built around 1900 with a stone outer wall and
brick inner.
I have currently got the kitchen totally gutted, including the ceiling
down
and quite a bit of loose plaster missing from walls.
At first I was intending patching up the missing plaster, re-boarding the
ceiling and having the whole lot skimmed.
I have now been wondering if there is any benefit to fitting slab
insulation
above the ceiling, or letting the escaping heat warm the bedroom above?
It's only worth insulating the bedroom from the kitchen if you like /
really/ cold bedrooms.

Also, the house has not got cavity wall insulation,
Is there a cavity between the outer and the inner wall? If so, get it
filled - it's a no-brainer.

is there much
benefit.when comparing energy savings to installation costs, in fitting
wall
insulation/plasterboard such as Kingspan K17/K18?

If you've got the wall stripped, then I would go and fit dry-lining
insulation. On the other hand, I'm a bit of a nut for extreme
insulation. If you are just looking to save money, then it's probably
not worth fitting insulation if you have filled the cavity (which will
be cheaper).

If you haven't got a cavity, then you should definitely dry line. (Of
course, the /better/ solution is to clad the /outside/ of the house,
so that the walls can act as thermal mass and slow down changes in
temperature.)
Hi,
Thanks for the replies.
The house has a cavity but I have been cautioned against getting cavity
insulation as it alows moisture to bridge from the stone layer through to
the inner brickwork.
Also, in the kitchen I have a solid floor, stone flags, bedded presumably
on hardcore/cinders or similar. I intend putting a water based underflor
heating system under the flags and having an exposed stone floor. Part of
the reason I am looking at insulation in the room is to help with the
warm-up time which I think will be longer with UFH than with the radiator I
currently have,(which SWMBO wants taking out to get furniture and units on
all walls).
Cheers,
Tony.
