Cavity Wall Insulation-good idea?

roddydogs

Anyone had any good/bad examples of CWI ? ive had an offer from the local council (over 65) for it to be done for "£200" normal price £500, (over 70 its FREE) ive heard of problems with "Cold Spots", anyone had it done/would recommend (or not) Thanks

I've had it done on two houses and both have been fine - on latest house as part of a number of measures (ie better loft insulation, TRV's etc.) I've halved my gas bill :-)

We've been contemplating it as we can get it done for £200. We have a 1950's semi but none of our neighbours have had it done so don't know what effect it will have on our type of house.

we had our 1930's semi done last year and the changes to the heat of the home have been very significant. It used to be 13 degrees in here in the mornings and now it is around 16-17
ours was totally free because we are on income support.

We gad ours done 6 mts ago on the Warm Front Scheme. We had free CWI and Free loft insulation. Its been great and made such a difference

Had mine done last year - and obviously it is great - highly recommended - with climate change it should be compulsory

CWI used to be all the rage a few years ago, but it seems to have fallen from favour recently. It is one of the most efficient and cost effective ways of saving energy.

It may be that because it isn't visible, like a wind turbine, posh double glazing or 15 different recycling bins lined up out side your house, it isn't seen as a "signal" that the particular householder is doing his bit to save the planet.

I was reading a magazine (in the doctor's) recently and CWI and loft insulation were highly recommended as "must dos" to save energy.
Three things that got the "thumbs down" were: Wind turbines, eco-kettles and solar powered lights.

I've been put off by concerns about damp mouldy patches appearing in walls where the CWI has failed or caused cold spots. From doing a bit of research a year or so ago I understand there are 2 different types of insulation and 1 is better than the other. I'm off to look again!

Found the site I read before. As I live in an exposed coastal area I have concerns.

Just to let you know that I spent loads of time researching CWI and very few said that they had a problem. A couple mentioned this thing about a 'cold spot' but they appreciated that a samll cold spot only actually highlighted that before the CWI the whole house was a cold spot ! Dont let people dampen your spirits about Small wind turbines - I have an interest so not allowed to mention a site on the thread but click my name and you see what I mean. With govt grants, inc electricity prices, reduced costs and inc efficency we are entering an age where they are becoming value for money

I had cavity wall insulation done nine years ago. All was well until last spring, when we noticed peeling wallpaper in one room. It's due to the insulation, and we're still deciding what to do about it. Up until then, we thought CWI was brilliant.
I live in a rural area , in a valley, and the dampness has appeared on the side of the prevailing wind. There is no shelter from other buildings nearby.

We had our house cavity filled with rock wool rather than foam 30 years ago. In four identical houses with identical lifestyles, we are the only house to have had it done and over the years gas central heating & hot water bills have been consistently lower than those of our neighbours so it proved an excellent investment, especially now fuel prices are soaring. If you're planning to stay in your house for a reasonable period it's well worth considering. If you're planning to move in the near future, I'd save the money and get your next house done.
