Solid wall insulation

[Chojin]

My house is an end of terrace with a solid wall and insulation in general is poor. A couple of the rooms have mouldings so I was thinking rather than deal with that and lose internal space with internal insulation, to go external instead.

I've got a company coming around tomorrow to survey my house. It doesn't sound like it is going to be cheap though (ECO grants are apparently quite small).

Has anyone had any experience with solid wall insulation?

Does it have good thermal performance? I've heard it reduces cold bridging.

Does it offer any kind of sound insulation? It would be nice to not hear people putting stuff in the bins outside.

Should the brickwork be repointed before the insulation is applied? I've noticed a few spalled bricks on the gable end and the pointing isn't exactly perfect.

Interesting comments guys.

I had an initial consultation today and was told that for aesthetic reasons my council wouldn't approve EWI unless it is clad with brick slips. That seems reasonable enough but the brick slips might double the cost of installation and make it even more out of reach.

Apparently the eligibilty criteria is changing in April and is planned to take into account the exposed exterior, so it might be worth waiting to see what is available then. I agree that it only makes financial sense if it's subsidised. Has anyone had a house valuation since getting the insulation fitted?

From what I gather any rising damp problems need to be addressed before the insulation is installed.

But what other dampness issues can occur? It seems like you just need to ventilate enough and not do things like drying clothes indoors etc.
