I recently got a flyer through the letterbox from a company wanting to
take
advantage of grants to insulate private homes. They say they will
insulate
my house with mineral wool for £150, and that it is £400 without the
grant.

Is it any better than polystyrene? Does mineral wool conduct damp, ie,
does
mineral wool "bridge" damp proof courses. I know polystyrene does not
conduct damp. Also, what would be the cost difference?

Thanks

Bob


Still think this type is best http://www.ncia-ltd.org.uk/page4.asp for the
money.



Thanks for the link. It seems all 3 types have much the same qualities, and
the same insulation value, with each having one unique quality (UF foam
makes formaldehyde, EPS balls blow into the loft and must be cleared up). I
read somewhere the blown mineral fibres have to be treated to stop damp
conduction. I can imagine it will settle over time as well.
