Hi all,

I want to get my house walls insulated. Half of it has solid stone walls.
The other half has cavity walls. I was hoping to get a grant to get the
walls insulated. However when a company came to look at the place, they
discovered that the cavities have "already been insulated" so I am not
eligible for a grant.

Actually, the only insulation in the cavities is some fairly useless 1"
thick polystyrene sheet, which is a waste of time, because it's not enough
to stop air movement within the cavity.

When I asked about paying for the work out of my own pocket, they said they
still won't do the job because they can't be sure what chemicals were used
for the original insulation and there could be some reaction between the
chemicals they use and the old insulation material. This sounds like pure
nonsense to me.

I pointed out that half the house is built of stone, and they said, "We
have to do at least 75% of the property"!

I would have thought that some company or other would be willing to come
along and pump polyurethane expanding foam into my cavities, regardless of
any thin polystyrene sheet that's in there. This would fill up the air gaps
so that there is no more air movement, and I'd get some degree of increased
insulation.

Can anyone advise th best way for me to proceed to get this sorded out once
and for all?

Many thanks,

Jim
