cavity wall insulation

[dustypuss]

hi what do you think about cavity wall insulation is it worth having it done .my thought on this is are( a cavity in a wall is to create a space to stop damp and noise from passing from the out side ) so if you fill it up with fome this could cause problems .

We had cavity wall insulation and it saved about 30% on our heating bills. There are different types and I would stick clear of the formaldohide foam type because as you say it bridges the cavity and damp can form. The other two are fibre glass and rockwool. Many people are allergic to the glass fibre type so I would plump for rockwool. This may deaden some noise from outside but do not place too much reliance on this. We had it for over 10 years and it made the house very cosy. The only problem we had was that ants built a nest in the cavity so make sure there are no small openings in the wall.

Kwicky, ants very often build nests in cavity walls, I don't think it had much to do with the insulation!! however, the insulation does make the nest a little more problematic to treat successfully

Hi Dustypuss,

Many years ago I bought a bungalow with one bedroom having three outside walls. I had problems in this particular bedroom with condensation. Our wardrobes were always damp and the walls behind them blackened.

I called in Rentokill to see if they could solve the problem. They suggested "Cavity Wall Insullation", and guaranteed that if it did not solve my problem they would refund my money and carry out any other work free of charge to remedy the dampness.

They drilled a series of holes in the walls and filled the cavity with "Rockwool"

My dampness was cured immediately, My heating bills were reduced overnight and both my wife and I were the happiest couple in the street.

In my opinion it was well worth the money.

Regards.

as I'm on benefit, I qualified for a Government grant for insulating my house. It has saved me a whole load of money, and my house is so cosy now. I would deffinately recommend 'Rockwool', Ab Fab.
