Wonder if anyone knows anything about the following. Our gaff was built
in 1979 and the first thing we did here was to have the cavity walls
filled with blown insulation which has improved the heat loss.

One of our neighbours has just asked who did ours as the two firms they
had in to quote said the cavity "wasn't big enough" to do that with
blown fibre. Can't remember who did outs a long time ago now. Cavity
here seems around a couple of inches, surely thats enough?..

Anyone else had that problem or heard of it?..

Cheers...
