We have a 13 y/o 3 bed detached house so no 'insulation/sharing heat' from adjoining properties. We have been offered this for £180.00 all in all for the external walls incl. adjoining garage.

Not expecting it to pay for itself straight away but will we notice the difference heat wise and financially? currently our gas (central heating, water heating and cooking) is going to be around 30.00 per month (averaged out) we have just swapped suppliers so not sure exactly how much yet.

Now typically i cannot find the quote with the companies name on it!

Thoughts please

Are you sure it doesn't already have it?

The people I have asked about this has all said it made the house feel much warmer, we are having ours done on Monday.

Geez thats another thing that my gparents house had ( which i should have bought ) , as well as solar .

Couldnt tell you whether it made heating a lot cheaper - i know they made a hellva mess tho putting it in

if youre gonna have it done id reccomend having the cavitys filled with polysterene/silver beads not rockwool, use a company that is ciga /bba approved like this one http://www.warmfill.com/index.htm.
my late father in law had the house done about fifteen years ago and they did such a bad job that there is cold spots and damp with the foam and water is passing to the inner cavitys,needs bricks taking out and cavitys emptied/vacuumed out.total cost due to the bodge £7000 and thats not a type error ! suggest get someone like them who survey your property and when it done ciga will send you a certificate with a 25 year guarantee.dave.

Get it done .By a reputable company .Nothing to lose if its done right .Had it done at ours and not really sure if its done much to be honest but it hasnt done any harm.

If you get it done get the loft done to current standards as well just dont go up there on a hot day or you'll cook.

jods

As long as you get it done by a reputable company (also check out if the local council give grants - they do in Herts) it's a no-brainer!

Go for it Paul

Paul, we had ours done last year and we have noticed a difference. We hardly put our heating on much past 18 degrees these days, though the next few days will put it to the test. We had it done by Dyson, not the vacuum cleaner company They made no mess and left things as before.

One of the main problems with cavity wall insulation is if you get a breach of water through the brickwork/stonework...In a detatched house this could be all of the external walls
The insulation then acts as a sponge and draws water into the inside of the house instead of running down of the inside of the cavity.
This then compounds the problem in that not only the outer wall needs repairing,but the cavity needs emptying and the internal wall needs repairing...

I have a good friend who is a surveyor and engineer for a British gas and he tells me all the horror stories that happen..I do think its a low ratio of people that do get a problem,but when it happens,it happens big!!!!

Personally......................I wouldnt have it done.

PaulC72

I agree.

Filling the void with something could lead to problems, it may not, it is hard to foresee the future


Also that seems a good price also as the would be doing the 4 house walls. I take it the garage is a cavity wall construction then not signle skin.

The polystyrene ***** therefore would make excellent sense ! as opposed to the pumped foam stuff

Yes..

Polystyrene ***** would be better....But its still creating a "bridge" between the inner and outer brickwork so water could easily transfer..

The air gap also lets air flow across the inside surface of the cavity which will keep any moisture at bay..

My walls are between 19"-22" thick with no cavity and my walls are cold at this time of year. That shows that the cold can penetrate deeply.

Yes its worth it.

For a house with no 'shared heat', cavity wall insulation (along with loft insulation) is one of the best ways of cutting down on energy used within the home.

It will benefit you in the winter with less heat esaping, and will also work in the summer by keeping the house cooler - something which a lot of people forget about.

There is also the reduction in noise that is experienced by some (not all) people who have insulation installed. Depends on the type and density of materials used.

£180 seems quite reasonable.

i thought all newish house have insulation in the cavity walls

Had ours done this summer. Even in this cold of -5. Heating is on minimum. Well worth it but as said, go with a reputable compny

SPEN555

What are the reputable companies for this?

The Zohan

Mornin' and thanks for the replies.

It is Whitewool which is spun man-made fibres (apparently) not a foam.

Company is Summit Insulation Ltd

My mam had hers done for £99. She had it done at the same time as replacing her heating system so hasn't really felt a difference from the insulation itself. The end wall that's always been the coldest still is, despite them apparently pumping more of the gloop in there. The end kitchen wall still gets so cold condensation runs down the inside.

They are coming up to retirement age though so got it done while they got it at a good price.

I had my house done - its probably 40 or 50 years old

Get the loft insulated too though.
I had the loft done and the walls done with the polystyrene *****.
I noticed a difference - house seems to retain the heat a lot more.

How much did it cost - I really can't remember.
I just know that when I had my new kitchen fitted, thousands of these little white ***** were everywhere when they were fitting the new extractor fan tube

I've been considering having this done too.....

so with the polystyrene ***** stuff - if you have, for example, a new electric socket fitted or, in the case above, you have a vent fitted, do you get a wall full of white ***** avalanching from the hole......

We'll a bit

It seems they are very we'll packed in.
Here's what happened.

I already have a vent hole, but it needed moved on the inside
I have the old vent hole filled and plastered over.

So - fitted drills new hold on inside, with the intention of connection to the old hole on the outside.

Drills away into the cavity - some insulation comes out.

But.......................
He had to move some insulation to route the duct to the old hole.
That was mainly when most of the stuff came out.
To be fair he did plug the gap pretty quickly and then went and got polystyrene from the packing of the units to "fix" it.
