I know this is slightly off-topic since not technically a DIY job, but
could I ask what thoughts people have on Cavity Wall Insulation.

I recall years ago that it sometimes had a bad name since it stopped
the airflow in the cavity and so could cause damp problems. At least
I think that is what was said negatively about it.

I have a 1900-ish mid-terraced house with the outer leaf stone and the
inner wall brick. It's nice and cool in summer but can get damn
freezing in winter.

My local supplier Powergen is offering CWI for £75 installed. Seems a
good price to me.

Any comments please?

To me too. Although it depends on the area of wall to be filled I suppose.

We had it done years ago and have been impressed. The whole house is
certainly more comfortable- but you'll still need heating in winter and
shade in summer.

get it down. at £75. i paid £225 and would do it again for double the price
couldnt belive the difference it made to our house. the materials they use
should not transmit water across. they should do an inspection first. if
damp is appearing then that would be an internal dpc matter

Its the second best thing you could do after loft insulation. It will
probably pay for itself after the first winter - as long as your
heating system is on thermostatic controls

How did you manage to get a quote so low off them - is it a special
offer?

I believe these are subsidised. If the OP has a detached house that is
heated
by solid fuel or electricity, then £75 is the going rate.

For me, with a semi that is heated by gas, I would have to fork out £125. I
suppose
the reasoning is that I am more energy efficient already, using gas so the
Gubmint
is not willing to subsidise as much as the detached house/electric heating
combination.

A detached home heated by gas, oil or LPG will cost £175.

A non-detached home heated by solid fuel or electricity costs only £50 for
cavity
wall insulation.

I had this done on my 3 bed semi 4/5 years ago. Made a huge difference keeping the house warm, & cooler than it used to be inside when the sun has been on the house all day. In fact, I notice "cold" walls more now - eg. the house has an integral garage & this is solid brick between the hall/living room & garage (ie, no cavity or insulation). This goes to show how much heat can be lost through uninsulated walls.

We had ours done a l-o-n-g time ago (well before there was any hint of
grants, we paid full wack). Immediately we noticed that there was
condensation on the double glazed window in the kitchen - previously it must
have been condensing on the colder walls.

That was proof to us of its efficiency.

Thanks for all comments, which are mainly positive. Just got to decide what
type and installer.

Inside the garage put Kingspan on the wall and cover with Ply or MDF and
then paint. May as well do it properly.

What reduction heating bills?

Yes a special offer in a pack of vouchers that Powergen sent out in
the mail.

Other offers in the pack include 4 free low-power light bulbs and £200
off a replacement A-rated boiler (though they have to appoint the
installer so may not be so cheap in the end).

Thanks to all for the replies. Mine is a 3 storey Victorian
mid-terraced.

I shall let you know what happens when I call them and they send their
'inspector' round.
