Cavity Wall Insulation

tsmiggy

I live in a 1980 semi detached house without any cavity wall insulation.Would i benefit greatly by having it done,what would be the approx cost,taking into account that i am self employed and do not have benefits to take into account.

cheers

Will reduce the heat lost via your walls so yes you'll benefit.

here (energy saving trust) for grants/offers. Not sure on costs as we qualified for free insulation..£250-ish i'd guess.

energy saving trust stuck something through our letter box the other day which stated £99 for a 3 bed semi.

Yes, you would certainly benefit, start by looking at your utility suppliers' websites, as they all offer subsidised deal, these are not means tested, though you might get a reduction based on age if there is someone of qualifying age in the house.

I would think long and hard before going ahead with CWI, just do a search on these forums for Cavity Wall Insulation & in particular look out for any posts on the subject from 'David Aldred'.
For a different perspective on those pro CWI have a look here

Good morning: more on CWI in Part C and the CIGA.

As i've said before probs are rare and the thousands/millions of people with it can't all be wrong. Nor would the grants be there to support it if it wasn't ok. Problems are more likely to be related to other building faults than the CWI itself. Besides it's backed by a 25-year government backed guarantee through CIGA. Most of the probs with CWI stemmed from the early days when urea formaldehyde foam insulation (UFFI) was used - discontinued in the 80s.

As well as discussing at length with my father (RICS chartered building surveyor)I did alot of reseach before i went ahead with cavity wall insulation...i scoured long and hard looking for probs..could barely find any! There are different types of CWI and my conclusion at the time was that blown glass-fibre (i.e Rockwool) CWI appears better than others with the properties it exhibits - that is what we had installed with no probs in the couple of years we've had it. If there was the hint of there being a real problem i'd not have considered it ..despite qualifying for free insulation ourselves.

We had our 1970's semi done a couple of years ago - very pleased we did as it makes the house much more even in temperature. I would be surprised if you did not feel and see the benefits of it (see them as in reduction of fuel costs).

It's not so much the frequency of any problem that puts me off it's the difficulty in proving the CWI is at fault & the difficulty in removing it if required. Salesmen carrying out surveys would always worry me. Having said that, my parents have had it for years and never had a problem despite being in a very exposed location.

Here is a rebuttal of 'Jeff's' opinion on CWI.
