Has anyone DIY'ed external insulation ? The cost was far too high
when I got a quote.

I have dabbled with the numbers and looked at some options for cladding.
I was considering battening over the insulation, then weather boarding
in either real wood, or a modern composite cement fibre board. I found
that the insulation itself can be quite cheap, and even the cladding not
too bad, but its often the sundry extras that add up; such as all the
trim parts for corners and window reveals.


The big problems I saw here (and with many like Victorian terraces with
solid walls) we

a. the roofline: no eaves at all at the back and only small at the front
(where there's no chance of planning permission for one house alone anyway)

b. risk of rot to to joists from interstitial (which the BRE found was
often ignored).

PS

On solid wall insulation the CCC assumes "cost-effective uptake in
around one million homes, focused on properties not connected to the gas
grid, alongside uptake in a further one million homes for wider fuel
poverty benefits" by 2030. I'd like to know how.
